API Check Valves

Description

API ball valve is used for the petrochemical industry pipeline media opening or cutting off, which is under the environment such as high temperature and high pressure, inflammable and explosive, corrosive and continuous operation, where require more requirements on valve sealing, material, corrosion.
Ccheck valve incorporates a metal-to-metal seal for high pressure, high-temperature environments where elastomer seals cannot be used. Primary applications for the check valve are high-pressure mud choke manifolds and high pressure lines.
