stainless steel 2 pcs ball valve Features 24 months guarantee Zero Leakage End flange ANSI B 16.1,EN1092,AS2129 Face to Face ANSI B 16.10 Top flange ISO 5211 Normal pressure: PN1.0/1.6MPa(150/200PSI); Class 125/150; JIS 5K 10K 16K 20K; Table D/E Body: CI/DI/WCB/ALB/CF8/CF8M Disc: DI/ALB/Rubber lined Disc/1.2501/1.4529/CF8/Hastelloy Alloy/Monel Stem: 410/416/304/431/17-4PH/316/monel Seat: NBR/Hypalon/EPDM/Neoprene/NR/Wear-Resistant EPDM/Viton/Silicon/Heat-Resistant EPDM/White EPDM/EPDM(NSF)/PTFE Suitable temperature: -10~200 Medium: Fresh water, sewage, sea water, air, vapor, food, medicine, oils, alkalis, salt etc. The top flange of the valves can be applied to manual , worm gear , pneumatic and electric actuator . The dimensions of D1 and n-d are the mounting specification , which can be China standard GB , ISO standard , ANSI standard , DIN standard ,JIS standard , AS standard and BS standard . Standard Test Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test. Seat Test: 1.1 times the working pressure with water. Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.
