S-1-250/15 Test bench for safety valves DN 10...250 mm (⅜...10″) PURPOSE Test benches are designed for hydraulic and pneumatic testing of spring loaded, pilot-operated, and other types of PSVs with DN 15...400 mm (1/2...16''), breather (pressure vacuum relief) valves DN 50...500 mm (2...20'') according to the following standards: • set pressure test according to API 526; • seat tightness test according to API 527; • breather (pressure vacuum relief) valves API RP 2000. TESTED VALVES • spring loaded PSVs; • pilot-operated PSVs; • breather (pressure vacuum relief) valves. ADVANTAGES ■ Clamping system design based on integrated high performance hydraulic cylinder, stainless steel base that serves as storage tank for hydraulic test medium. Clamping of valve need to be tested, provided by test table actuated by hydraulic cylinder and three synchronized claws thats centering and fastening of inlet PSV flange. ■ Increased inner diameter of test system tubing and high pressure hoses provides dynamic spool lifting during set pressure test, as well as smooth and accurate reseating, same time serves to avoid the seats surface damages while closing. ■ Use of special Nickel and Chrome coatings and stainless steel elements of clamping unit water wetted surfaces provides stable operation in hard environmental conditions with high level of humidity. ■ «Pockets» for set of sealing adapters storing. ■ Adapters for PSV inlet flange face sealing for valves with DN 15...400 mm (1/2... 12'') of the following types: FF, SG, RF, LM, LG, RTJ as per ASME B 16.5. ■ Plugs for PSV outlet flange face sealing with fittings for quick connection of drop/bubble counter tubing.
