Overview

PVC diaphragm valve consists of a UPVC or CPVC body with an inlet and outlet and a diaphragm that separates these two ports. When the valve is in the closed position, the diaphragm seals against the body, preventing the flow of fluid.

Tips: Are diaphragm valves directional?

Diaphragm valves are indeed directional in nature. They consist of a flexible diaphragm, typically made of rubber or another elastomeric material, which moves up and down to control the flow of fluids through a pipe. This diaphragm acts as a barrier between the fluid and the valve body, and its movement is regulated by a stem or a compressor.

The directionality of a diaphragm valve is determined by the design and installation. Fluid flow typically enters from one side of the valve and exits from the other. It's crucial to install diaphragm valves with the flow arrow indicating the correct direction, ensuring that the diaphragm functions effectively. If installed in reverse, the diaphragm may not seal properly, leading to leaks and reduced control over fluid flow. Proper installation with attention to the flow direction is essential to their efficient operation.
