High pressure wafer check valve
High pressure wafer check valve
Product Overview | The High Pressure Wafer Check Valve is a compact, robust non-return valve designed for high-pressure applications in oil & gas, petrochemical, and power generation industries. Featuring a wafer-style design, this valve is installed between flanges, making it an ideal choice for systems where space and weight are critical considerations. Constructed from carbon steel, stainless steel, or alloy steel, this valve is engineered to withstand pressures up to Class 900 (ASME B16.34) and high temperatures (up to 800°F/427°C). Its swing disc or dual disc design ensures reliable sealing with minimal pressure drop, while its compact form factor simplifies installation and reduces overall system weight. |
Key Features | High Pressure Rating: Rated for Class 150 to Class 900 (ASME B16.34), suitable for pressures up to 150 bar (2,175 psi). Wafer Design: Compact and lightweight, ideal for space-constrained installations. Installed between flanges, eliminating the need for additional bolts or gaskets. Durable Construction: Body materials: Carbon steel (ASTM A216 WCB), Stainless steel (ASTM A351 CF8M), or Alloy steel (ASTM A217 WC6/WC9). Internals: Stainless steel or Inconel trim for corrosion resistance and extended service life. Reliable Sealing: Swing disc or dual disc design ensures immediate sealing upon flow reversal. Reduces water hammer effects in high-pressure systems. Compliance: Meets API 594, ASME B16.34, and NACE MR0175 standards for high-pressure and sour service applications. |
Operational Advantages | Space-Saving Design: Compact wafer style reduces installation space and system weight. High Reliability: Designed for critical high-pressure applications with zero leakage (Class VI). Energy Efficiency: Minimal pressure drop reduces pump energy consumption. Ease of Installation: No additional bolts or gaskets required; fits between standard flanges. |
