A Tomex PVC check valve is an automatic safety device designed to allow fluids and gasses to flow in one direction and prevent reverse flow. Under pressure, fluids enter the valve at the inlet where they force the disc off the seat of the valve and exit through the outlet.
Flow continues steadily as long as the pressure is maintained to keep the disc open. Once there is a pressure drop, the disc automatically returns to its seat to shut off the flow.
The pressure that opens the valve is referred to as cracking pressure, which can vary from 3 psi to 350 psi depending on the size, purpose, and function of the check valve.
Check valves ensures gasses or liquids are flowing in the right direction, and create tight seals to prevent leaks. By controlling the flow of liquids, check valves protect pumps and compressors from serious damage.#pvccheckvalve #checkvalve #backflowvalve
