Product Overview

The High Pressure Wafer Check Valve is a compact, robust check valve designed for high pressure applications in the oil and gas, petrochemical and power generation industries. The valve has a butt-mounted design and is mounted between flanges, making it ideal for systems where space and weight are critical.

Constructed of carbon, stainless, or alloy steel, the valve can withstand pressures up to Class 900 (ASME B16.34) and temperatures up to 800°F/427°C. The swing-valve or double-valve design ensures reliable sealing and minimizes pressure drop, while its compact profile simplifies installation and reduces overall system weight. The swing or double flap design ensures reliable sealing and minimizes pressure drop, while its compact form simplifies installation and reduces overall system weight.

Product Characteristics

High-Pressure Ratings: Pressure ratings from Class 150 to Class 900 (ASME B16.34) for pressures up to 150 bar (2,175 psi).

Counter-clamp design: compact and lightweight, ideal for space-constrained installations. Mounts between flanges without additional bolts or gaskets.

Durable construction: Valve body material: carbon steel (ASTM A216 WCB), stainless steel (ASTM A351 CF8M), or alloy steel (ASTM A217 WC6/WC9). Internal components: Stainless steel or Inconel internals for corrosion resistance and longer service life.

Reliable sealing: Oscillating flap or double flap design ensures immediate sealing in the event of reverse flow. Reduces the effects of water shock in high-pressure systems.

Compliance: Meets API 594, ASME B16.34, and NACE MR0175 for high pressure and acid applications.

Product Advantages

Space-saving design: Compact, clamp-on design reduces installation space and system weight.

High Reliability: Designed for critical high voltage applications with zero leakage (Class VI).

Energy saving: Minimum pressure drop reduces pump energy consumption.

Easy to install: no additional bolts or washers required; fits between standard flanges.
