Temperature measurement provides information on the temperature of the process medium, on the basis of which the process is monitored or controlled.
Selection of the temperature gauge
We help in selecting a temperature gauge that meets the requirements of the application.
Nuova Fima’s temperature gauges are well suited for demanding industrial applications. We have selected reverse-mounted gauges as our stock models, with a dial size of 100 mm, enclosures in AISI 304 and protective pockets in AISI 316. Special gauges are available upon request.
Threaded and welded protective pockets keep the pressure behind the protective pocket even in situations where the temperature gauge is removed from the system, for example during replacement.
Pressure gauges are display-based meters, where the information about the system’s pressure is shown on the dial.

NUOVA FIMA’s pressure gauges are well suited for demanding industrial applications as well as the food industry.
For the food industry, pressure gauges can be equipped with hygienic fittings.
From our extensive range, we have selected dampened gauges for our stock with dial sizes of 100 and 160 mm in diameter, housings in AISI 304, and wetted parts in AISI 316. Pressure gauges are also available in your selection with ATEX approvals.
Pressure gauges can be equipped with alarm switches.
Differential pressure transmitters measure the pressure difference and transmit electrical data to the system. For example, in critical applications, the differential pressure measurement can be made across the system’s filter. If the filter begins to clog and the pressure difference increases, an electrical alarm is sent to the system for maintenance procedures.
Because differential pressure transmitters are very precise and measure extremely small pressure differences, they can also be used for level measurement, which is based on the hydraulic head of the liquid. Especially in high-pressure systems, this pressure-difference-based measurement is an excellent alternative to other level measurement methods.
In flow measurements based on pressure difference, the differential pressure transmitter is also an essential component for measurement accuracy.

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.

Pressure classes: from a few millibars to over 5 000 bars Materials: nickel, RST/HST, hastelloy, inconel, monel, tantalite, titanium, silver, gold, graphite, etc. Other names: rupture disc, rupture membrane, explosive disc, rupture disc, bursting disc
What is a Rupture Disc
Rupture discs (Rupture / Bursting Discs) are also called rupture discs, rupture membranes, and explosive discs. The names aptly describe the disc’s function. A rupture disc is a specially engineered metal or graphite disc that is manufactured with a specific rupture pressure. In a process pipe, the rupture disc is completely sealed and retains the pressure behind it, provided the rupture pressure is not exceeded. When the pressure is exceeded, the rupture disc bursts, releasing the pressure out of the system. Once the pressure has dropped back to the normal line, a new intact disc is installed.
Rupture discs can be equipped with sensors and/or gauges that indicate the disc’s rupture.
A rupture disc is usually installed in a separate holder. The holder is a good solution because the risk of changes in rupture pressure during installation or operation is significantly smaller.
A rupture disc can also be used together with a safety valve, in which case it protects the safety valve from, for example, an aggressive or corrosive medium.
An explosion panel works in a similar way, but they are typically used for structural explosion protection, for example in dust explosions.
Rupture Disc Selection
Rupture discs are especially significantly lighter than safety valves of equivalent size, particularly in larger dimensions.
When selecting and sizing a rupture disc, several factors must be considered. These include, for example, operating pressure, desired rupture pressure, whether the load is pulsating or steady, whether the disc needs to withstand vacuum conditions, whether disc fragmentation is acceptable, whether rupture information should be transmitted to the control room, liquid/gas applications, etc. Rupture discs come with different manufacturing and rupture tolerances, which are nowadays incorporated into the operating range tolerance (min./max.). Our sales team will size and select the appropriate, cost-effective rupture disc from ZOOK’s range on your behalf.
Material options include, for example, nickel, RST/HST, hastelloy, inconel, monel, tantalite, titanium, silver, gold, graphite, etc.
Media include, for example, steam, other gases, liquids, (liquid) nitrogen, oxygen, carbon dioxide, ozone, helium, fuels, cryogenic fluids, etc.

Size: DN 10-300 Pressure class: PN 16-500, ASME 150-2500# Temperature: -200 °C….+400 °C Operating pressure: max 300 bar Material: GG-25, GGG 40.3, GS-C 25, AISI 304, AISI 316, red brass, titanium, hastelloy etc. Connecting ends: flanged, screwed sockets Other names: relief valve, full lift safety valve
What is a Safety Valve?
A safety valve is a critical safety device designed to release pressure from a process when it exceeds a predetermined set pressure. The set pressure is maintained by a spring compressed between spring plates. The upper end of the spring plate is locked, allowing the force to act only downward. If the pressure beneath the disc surpasses the spring force, the safety valve opens. The valve recloses when the pressure drops to 10–30% below the set pressure. Therefore, the operating pressure must not be too high.
Safety Valve Selection
We size and select safety valves suitable for our customers’ applications. Please provide the application and process parameters to our sales representative, who will assist in selecting the appropriate safety valve.
We maintain a substantial buffer stock of various body types and springs. For urgent deliveries, we can quickly and reliably set the valves to the desired set pressure. We also offer safety valve maintenance services.
Our product range includes a comprehensive selection of safety valves to meet different process requirements.
The range includes both low-lift and full-lift safety valves, valves with open and closed bonnets, and hoods ranging from open to gas-tight models. This selection ensures suitable models for steam, liquid, and gas applications. Dynamic and/or static backpressure must not exceed 10% of the set pressure. If this cannot be avoided, the safety valve can be equipped with a bellows.
Safety Valves for Steam
In steam processes, full-lift safety valves are typically used, where the inlet flange is two sizes smaller than the outlet flange. This design accounts for the expansion of the medium and provides better capacity. Our product range includes both DIN and ASME standards.

Cryogenic safety valves are available in sizes DN 6–50 and can withstand pressures up to 550 bar, operating within a temperature range of -270 to +400°C. The safety valves are primarily made of stainless steel, but they can also be manufactured from bronze and brass.
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.
Needle valve selection
