Stop-Check Valves:

Versatile Solutions Providing Unmatched Fluid Control in High-Pressure Applications

CPV’s stop-check valves provide soft-seated, bubble-tight performance for long-lasting durability in high-pressure applications. These valves provide the perfect synergy between a shutoff valve and a check valve, offering versatility that empowers you to streamline your processes and enhance system efficiency.

In the ‘closed’ position, the valve remains sealed regardless of system pressure, providing you with absolute control over fluid flow. When you switch to the ‘open’ position, it operates as a check valve, permitting flow in a single direction, guaranteeing efficient and reliable operation.

How is a stop-check valve unique?

A stop-check valve is unique because it combines elements of both globe stop valves and check valves. Unlike a standard globe valve where the valve stem is fixed to the globe disc, in a stop-check valve, the stem head essentially floats. This design allows the stop-check valve to serve as both a globe valve and a check valve, providing precise control over fluid flow when closed and preventing reverse flow when open.

What are the key advantages of stop-check valves, and in which applications do they prove to be particularly valuable?

Their versatile design makes them highly valuable in applications demanding precise control over fluid flow and the prevention of backflow. Whether in industrial processes, pipeline systems or plumbing setups stop-check valves offer a versatile and reliable solution to maintain fluid flow in the desired direction while effectively preventing unwanted reverse flow, ensuring smooth and efficient operations.
