Technical Specifications and Design Principles of Wafer Check Valves

A high quality wafer check valve manufacturer distinguishes itself through meticulous engineering and adherence to global standards. Wafer check valves, designed to fit between two flanges, typically consist of a body, disc(s), hinge pin, and spring(s).

Key Components & Materials:

• Body: Often constructed from materials like Carbon Steel (A216 WCB), Stainless Steel (A351 CF8, CF8M, CF3M), Duplex (A995 4A, 5A), or Bronze (B61, B62) depending on media corrosivity, temperature, and pressure.
• Disc: Matched to the body material, or sometimes with specialized coatings or elastomers (e.g., EPDM, Viton, NBR) for enhanced sealing and chemical resistance.
• Spring: Usually Inconel or Stainless Steel, chosen for optimal closing force and resistance to fatigue.
• Seat: Can be integral to the body or a replaceable soft seat (e.g., PTFE, RPTFE) for bubble-tight shutoff.

Design Types & Parameters:

• Single Disc Wafer Check Valve: Simple design, suitable for moderate flow conditions.
• Dual Disc Wafer Check Valve: Features two semicircular discs, offering reduced pressure drop and faster closure, minimizing water hammer. This design is prevalent due to its superior performance characteristics.

Common Parameters:

• Sizes: Ranging from DN15 (NPS 1/2") up to DN1200 (NPS 48") or larger.
• Pressure Ratings: ANSI Class 150 to Class 2500 (PN10 to PN420) and beyond for high-pressure applications.
• Temperature Range: From cryogenic applications (-196°C) to high temperatures (+550°C), depending on material selection.
• End Connections: Wafer, Lug, and Flanged types. Wafer type is most common due to its compact nature.
