Other names: filler valve, single check filler valve, double check filler valve
What is a filler valve?
The design of the filler valve facilitates and speeds up the filling of the tank. Filler valves can be used as filling connections for fuel tanks, storage tanks, and mobile tanks.
The upper and lower parts of the filler valve can be serviced without removing the valve from the tank. The recoil features of the upper and lower parts are spring-loaded so that the filling connection closes after the flow stops. The stopper is attached to the valve by a chain.

Shut-off and regulating valves can be equipped with an actuator, allowing the valve to be controlled from a location other than in its immediate vicinity. Whereas pneumatic actuators use compressed air to operate, electric actuators use electricity.
In large actuators, short-circuit motors (synchronous motor) have traditionally been used, in which the valve is directed in the desired direction by changing the polarity of the rotor windings with alternating current. Actuators are supplied only for a specific voltage and frequency.
Brushless DC motors (BLDC) have become common in smaller actuators, enabling the use of 24 VDC as well as providing flexibility with AC voltages. For example, as standard, the ARI-Premio-Plus actuator operates within a voltage range of 90–264 VAC, 47–63 Hz.
The advantage of electric actuators is their significantly greater force output relative to their size compared to pneumatic actuators. Therefore, they are well suited for large, high-force valves such as wedge gate valves.
Selection of an Electric Actuator
We assist in selecting an electric actuator that meets the requirements of your application.
Our product portfolio includes ARI PREMIO electric linear actuators, whose power capacity is designed in a sensible and cost-effective manner for ARI shut-off and control valves. We also offer other electric actuators available on the market, such as AUMA, Bernard, and Rotork.
Others: suitable for both linear and rotary movements Other names: diaphragm actuator, pneumatic actuator, rack and pinion actuator, scotch-yoke actuator
What is a pneumatic actuator?
A shut-off valve can be equipped with an actuator, allowing the valve to be controlled from a location other than its immediate vicinity. In pneumatic actuators, compressed air controls the actuator to open or close.
In dual-action actuators, compressed air both opens and closes the valve.
In single-action models, the operation can be designed so that compressed air either opens or closes the valve, and an internal spring within the actuator performs the opposite movement if the compressed air is lost.
The advantages of a pneumatic actuator include its quick response and resistance to vibration compared to electric actuators.
Selecting a Pneumatic Actuator
Pneumatic actuators are divided into rotary actuators (90º / 120º) – which are suitable for ball, butterfly, and plug valves – and linear actuators, which are suitable for sleeve and slide valves.
Our stock of rotary actuators includes GT (gear) and RC (scotch-yoke) single- and dual-action pneumatic actuators. Upon request, we also equip valves with actuators from other brands.
In ARI-Armaturen sleeve valves, we use the factory’s own linear DP actuators.
Pneumatic actuators can be equipped with various limit packages, positioners, and solenoid valves.
We assist in selecting the pneumatic actuator that meets the requirements of your application. Contact our representatives for more information.
Sizes: From 1/4″ Pressure Classes: PN 100-630 Materials: brass, C 22.8, AISI 316 Connection Ends: threaded, weldable, weldable/threaded Other designations: pressure gauge valves, instrument valves
What is a pressure gauge valve?
Pressure gauge valves and instrument valves are shut-off valves. For example, a pressure gauge valve is installed in a pipeline as the shut-off valve for a pressure gauge. The DIN classification for gauge valves is up to 120 degrees Celsius. Very generally, at temperatures above this, a water lock pipe is installed in the pipeline before the pressure gauge valve.
Selection of a pressure gauge valve
Pressure gauge valves come in various types, but generally they are supplied with or without a check flange. A model equipped with a check flange, so-called engineer valve, is intended for applications where an external inspector can quickly check the system pressure with their own pressure gauge.
We assist in selecting pressure gauge valves and instrument valves according to the requirements of the application. Ask our contact persons for more information.

What is a solenoid valve?
Solenoid valves are used to control pneumatic actuators as well as process valves. They are either direct acting, pilot-operated, or operate with forced pilot control.
A pilot-operated valve allows for higher capacities than a direct acting solenoid valve. Forced pilot control is suitable for applications with low line pressure.
Choosing a Solenoid Valve
Solenoid valves are available in different voltage types, AC and DC, two-, three-, or four-way configurations. The valve bodies are made of aluminum, brass, and acid-resistant steel.
Our range includes all the electrical approvals required by the industry to use the valve in explosive atmospheres.
Solenoid valves are suitable for air, water, oil, and steam.
We assist in selecting a solenoid valve that meets your application requirements. Contact our representatives for more information.

Size classes: R 3/8 Pressure classes: PN 10-400 Materials: brass, AISI 316 Connection ends: threaded, welded Other designations: needle valve
What is a needle valve?
Thanks to its needle-like seat structure, the needle valve can be used, for example, as a sampling valve in applications where pressures are relatively high. Needle valves are also known as pressure gauge valves, in which they are installed under pressure gauges or pressure transmitters as shut-off valves.

We assist in selecting the appropriate needle valve to meet the requirements of your application. Ask our contact persons for more information.
2-, 3-, 4- and multi-seat plug valves Sizes: DN 15-400, NPS 1/2 Pressure classes: PN 10-100, ANSI 150-600 Materials: GGG 40.3, GS-C 25/WCB/LCB, other materials upon inquiry Lining: PFA, FEP, PVDF, if necessary plug coated with PTFE Operation: hand lever, screw operation Connection ends: flanged Other names: plug valve
What is a plug valve?
Plug valves operate similarly to ball valves. Instead of a ball, a wedge-shaped plug—with a drilled flow opening—functions as the closing element.
There are both soft-sealed and metal-sealed plug valves.
Choosing a plug valve
A soft-sealed plug valve is excellent because there is no free space between the plug and the body, unlike, for example, in a ball valve, as it is completely sealed with lining.
This feature is beneficial because if the process medium contains sand-like particles, they could flow into the intermediate space (cf. ball valves) and quickly damage the seal.
The advantage of a metal-sealed plug valve is its higher pressure and especially temperature resistance.
The valves have the following approvals: TA-Luft, AD-2000/TRS-Nr. 45, Fire-Safe API 607, and UOP.
Plug valves are available in multi-stage versions and can be equipped with pneumatic or electric actuators.
We assist in selecting and sizing a plug valve that meets the requirements of your application.

Sizes: from DN 15 Pressure classes: from PN 4 Connection types: threaded, weldable, flanged, between flanges Actuators: electric and pneumatic actuators Other names: knife gate valve, wedge sliding valve, knife gate valve, actuator operated gate valve
What is an Actuator-operated Gate Valve?
A gate valve can be equipped with an actuator. This allows the valve to be operated from a location other than in the immediate vicinity of the valve.
The wedge sliding gate valve requires more force compared to other types of shut-off valves. Therefore, the most common actuator for them is an electric actuator.
For knife gate valves, due to the low torque requirement, we recommend using a pneumatic actuator because of its high closing speed.
Selection of Actuator-operated Gate Valves
We assist in selecting and sizing an actuator-operated sliding gate valve that meets the requirements of the application. We collaborate with the most common electric actuator manufacturers, such as Auma, Bernard, and Rotork.
Actuators can be equipped with additional devices or Fail-Safe functionality, whereby the actuator drives the valve to the closed position, even if the power to the system is lost. Additionally, they can be fire protected.
Sizes: DN 50-1600 Pressure Classes: PN 10-100 Materials: cast iron, spheroidal graphite cast iron, ductile irons, acid resistant steels Temperatures: -40 °C…+400 °C Connection Ends: between flanges Others: EN ISO and ANSI standards Other Names: plug door, sluice gate, knife gate valve
What is a knife gate valve?
Knife gate valves with annular seals perform best in applications prone to dirt accumulation with thick and slurrying media, where the cutting properties of a straight knife gate can be utilized. All knife gate valves are suitable for narrow spaces thanks to their short L-dimension.
Knife gate valves perform best in challenging conditions and with difficult media such as water containing solids, paper mill slurries, black liquor, recycled paper water lines, sugar-rich waters, syrup and juice lines, high-viscosity lines, pellets, powders, abrasive media, carbon dust, dust, sludges, cements, etc.
Knife Gate Valve Selection
Our range includes both annular seal and O-ring sealed knife gate valves. The advantage of the O-ring sealed models is their affordable acquisition cost. These valves are only unidirectionally tight and have relatively poor resistance to solid concentration.
We assist in selecting and sizing a knife gate valve that meets your application requirements.
High-Quality Sealing Solutions
In applications where there are problems with conventional gate valves, the transverse seal structure is used. In these valves, transverse upper seals of on the closing flap substitute for the gland.
The design of the seal and a scraper integrated into the seal keep the knife gate surface clean whilste isolating the gate. In addition, the two-component body has a peripheral seal that seals the gap between the disc and the body. Unlike in the case of O-ring models, the medium does not induce seal wear. The conventional particle-collecting pocket does not form on the bottom of the gate; instead, the disc is sealed tightly against the peripheral seal and metal valve body. This also renders the valve bubble tight, which cannot be achieved in any other way.
The valve body supports the disc, preventing solid particles (debris, loose material, etc.) from bending the disc and causing valve leaks. The pressure rating is typically PN 10, but ratings up to PN 100 are available.
The valves can be modified for various applications. Tell us your valve challenge, and we will find a solution for you.
