Chemical Low Pressure Non Slam 4 Inch Wafer Type Dual Plate Check Valve With CAD Drawings

The Low Pressure Non-Shocking 4 Inch Wafer Style Double Plate Check Valve is a valve designed to allow fluid (usually liquid or gas) to flow in one direction while preventing backflow in the opposite direction.
Here are some key features of this valve:
1. Size: The valve is designed to fit 4" diameter piping systems.
2. Pressure Rating: It is designed to handle low pressure applications, usually ranging from a few PSI (pounds per square inch) to a specific maximum pressure, depending on the manufacturer's specifications.
3. Non-popping: The valve is carefully designed to prevent the valve from popping or closing suddenly, which would cause water hammer in the piping system. Water hammer is a hydraulic shock that occurs when fluid flow stops or changes direction rapidly. This could damage the valve and other components of the system.
4. Wafer style: The valve is a wafer style design, which means it is sandwiched between two mating flanges and held in place by bolts or studs. This design requires no additional flanges or end connections, making it compact and lightweight.
5. Dual Plate Design: The valve has two plates hinged at the center, allowing them to swing open and close according to fluid flow. The dual plate design provides a more compact and efficient solution compared to traditional swing check valves, especially in applications where space is limited.
