A216 WCB Ball Valve

ASTM A216 WCB ball valves are for non corrosive service applications from -29ºC (-20ºF) to 425ºC (800ºF) for petrochemicals, gas, water, steam and general industrial applications.

For H2S Sour Service, Relia’s A216 WCB ball valve are fully conforming to NACE MR0175 & MR0103/ISO 15156. This is for petroleum, natural gas and geothermal production services containing small amounts of H2S.
