Cover a large variety of types, materials and options to fit any application:
Connection sizes from 3/8” to 2” provide high suitability to the application
Threaded connections, male and female, according to all international standards guarantee worldwide applicability
Flanged connections according to ANSI, DIN and JIS guarantee worldwide applicability
Inlet pressure ratings up to class 2500 to fit all required design pressures
2 standard body materials, stainless 316L and A105 (carbon steel) as well as 4 standard seat materials, stainless steel, PTFE, PCTFE and VESPEL, can be selected.
All parts can be machined from bar materials to cover special material requirements such as hastelloy®, Duplex, super Duplex, Tantalum or Titanium within unrivalled lead time
Set pressure up to 365 bar/ 5294 psig make compact performance safety valves suitable for all industrial processes
Operating temperatures from -29°c to 220°c / -20.2 to 428°F cover a wide range of applications
One design and spring (single trim) for steam, gas and liquid applications reduces the number of spare parts and ensures low cost maintenance management
Ringless design needs no trim adjustments for easy maintenance.
One– piece spindle reduces friction which leads to high operation accuracy
Self – draining body design, avoids residues and reduces corrosion
Can be customized with a great variety of options, e. g,:
Special connections specified by the customer for optimized adaptation to the plant
Stellited or hardened metal sealing for longer product life
Soft seat solutions for superior tightness
Stainless steel bellows for back pressure compensation
Base/ inlet body, body, bonnet and all internal parts can be produced in special materials exactly to meet customer specifications and requirements
Typical applications for NEEV safety valves are:
Air/ gas compressors and pumps
Technical gases and CO2 plants
Cylinder filling stations
Pressure vessels and piping systems containing gas, air liquid or steam.
