Although wafer check valves and swing check valves serve the same functions—such as preventing backflow, enabling low-load pump startup, and reducing water hammer—they differ significantly in design standards, structural features, and areas of application. This article analyzes their differences across five key aspects to help users make more informed decisions when selecting a suitabl...

In the industrial valve field, the wafer check valve is an important one-way valve widely used in various fluid pipelines. Due to its compact design and excellent performance, it has become the preferred choice in many operating conditions.   Basic Function of the Wafer Check Valve The primary function of the wafer check valve is to prevent the backflow of the medium in the pipeline. Its inte...

Every heating contractor moving into an empty boiler room ---- This room is usually the size of a small closet ---- must have his piping system outlined in his mind around the type of boiler and heat distribution system he will be installing. One of the main criteria for determining the plumbing configuration is the little check valve. First, let's look at the three most common types of check valv...

For high-pressure piping systems where multiple pumps are used together, the problem of water hammer in the piping system is even more acute. Water hammer is a pressure wave of the ever-changing flow in a pressure pipe, which is a hydraulic shock caused by a pressure rise or fall due to the change in the fluid flow rate in the pressure pipe. Water hammer is the combined result of the inc...

An axial flow silent check valve’s disc is held in place by a spring. This upgraded structure design brings about many advantages. First, as its name indicates, the streamlined axial flow path through full-port expanded body prevent turbulence, erosion and vibration, which eliminate the process downtime and maintenance cost. Second, the full port passage and high-pressure recovery of the venturi-s...
