Nuova General Instruments – Technical profile of a safety valve and overflow valve manufacturer

Nuova General Instruments is an Italian manufacturer of spring-loaded safety valves and overflow valves for pressure equipment, piping systems, compressors, steam generators, refrigeration circuits, process skids and industrial utilities.

The company manufactures safety valves in brass, stainless steel, mixed construction and PVC, with threaded, flanged, sanitary and API-type configurations. The range represented through Philippopoulos S.A. includes UNI / ANSI flanged safety valves, API 526 flanged safety valves, free discharge safety valves and piped discharge safety valves.

Main product groups include:

• free discharge safety valves,
• piped discharge safety valves,
• high-pressure safety valves,
• flanged UNI / ANSI safety valves,
• API 526 safety valves,
• PVC safety valves,
• overflow valves.

A safety valve is a pressure safety device. It must be selected according to the relief scenario, not only pipe size. Required data include set pressure, protected equipment design pressure, required relieving capacity, medium, temperature, back pressure, discharge line arrangement and certification requirements.

Free discharge valves vent directly to atmosphere and are suitable only where the discharged medium and location make this acceptable. Piped discharge valves are used when the relieved fluid must be routed to a safe point, vent header, scrubber, flare or collection system.

High-pressure safety valves require careful verification of spring range, connection rating, seat tightness, body material and calibration certificate. PVC safety valves are used where chemical compatibility requires non-metallic construction, within pressure and temperature limits.

Overflow valves are used for pressure control or bypass applications. They should not automatically be treated as certified safety valves unless the applicable documentation and regulatory framework confirm that use.

Nuova General products are relevant for pressure equipment engineers, process engineers and maintenance teams working with overpressure protection.
