Wafer Check Valve
Wafer Check Valve Manufacturer
MVS Valves offers robust and compact Wafer Check Valves designed to deliver reliable backflow prevention in various process, water, and industrial pipeline systems. The single plate wafer type check valve features a wafer style single disc swing type design that fits between flanges in a space-saving sandwich configuration. Conforming to API 6D and ASME B16.10 face-to-face standards, these valves are perfectly suited for pump discharge duties and applications requiring efficient shut-off performance with minimal pressure loss.
The design incorporates an eccentric-mounted hinge pin and a precision-engineered disc seat that ensures positive sealing of the returning media. Offered in Swing short wafer carbon steel check valve and Swing short wafer stainless steel check valve variants, the Wafer Check Valve provides exceptional durability under varying pressure and flow conditions. For demanding applications, the SS 316 single door wafer check valve offers added resistance to corrosion, while the carbon steel wafer body thin type single plate wafer check valve is ideal for high-strength and budget-friendly installations.
For operations that require enhanced responsiveness, MVS also manufactures Wafer Check Valves with a spring-loaded mechanism on request. This feature allows for quicker closing action and helps prevent water hammer, making them suitable for vertical and horizontal pipeline orientations. Whether it’s the Wafer Swing Check Valve, Stainless Steel Wafer Body Thin Type Single Plate Wafer Check Valve, or Wafer Style Single Disc Short Pattern API 6D Check Valve, each model guarantees reliable flow control in a compact footprint.
The combination of advanced manufacturing, high-grade materials such as carbon steel and stainless steel, and compliance with international standards like ASME, BS, and DIN makes MVS’s Single Disc Wafer Check Valves a trusted solution across critical industries. Their simple yet rugged construction ensures long service life, ease of installation, and consistent sealing performance, making them the go-to choice for efficient non-return flow management.
