Product Description

The Disc Check Valve from Perfect Engineering Services is a high-performance, compact non-return valve engineered to prevent backflow in piping systems. Designed with precision and durability in mind, this valve is available in sizes ranging from 15 mm to 200 mm and supports pressure ratings of Class 150/300. With wafer-type end connections, it ensures easy installation between flanges.

Manufactured in superior grades of stainless steel—SS-304 and SS-316—the valve offers excellent corrosion resistance and long-lasting service, even in demanding industrial environments. A soft seating option is available for applications requiring enhanced sealing performance.

Working Principle

The Disc Check Valve operates on the spring-loaded disc mechanism. During forward flow, the pressure of the fluid pushes the disc away, allowing unrestricted flow. When the flow stops or reverses, the spring forces the disc back onto the seat, preventing any backflow. This self-acting, automatic operation ensures protection of pumps, compressors, and other critical equipment from reverse flow damage.

Key Internal Components:

• Disc: SS304/SS316

• Spring: SS304/SS316

• Spring Washer: AISI304/AISI316
