Swing Check Valve/High Pressure Forged Steel One Way Check Valve

Swing Check Valve/High Pressure Forged Steel One Way Check Valve. High Pressure Resistance: Withstands working pressures from 2,000 psi to 20,000 psi using alloy steel forging. Corrosion Resistance: Hardalloy hardfacing and sulfur-proof steel core ensure resistance to H2S and CO2 environments. Reliable Metal Seal: Self-energizing metal seal between valve core and body improves with higher medium pressure. Anti-Stuck Design: Upper and lower pressure balance ensures smooth core movement and prevents sticking. Versatile Application: Suitable for oil, natural gas, mud, and corrosive gases in industrial and household usage. Precision Engineering: Minimal assembly clearance (0) reduces erosion of bolts and holes by corrosive media.
