Structural Features of CPVC Plastic Diaphragm Valve
Wide Application: Designed for the transportation and shutoff of corrosive media, as well as flow regulation, with an operating temperature range of -30°C to 95°C.
High Corrosion Resistance: All wetted parts are assembled from CPVC injection-molded components, ensuring excellent corrosion resistance. The valve is lightweight, easy to operate, and a cost-effective alternative to stainless steel valves.
Durable Diaphragm: The sealing diaphragm is made from F46 or PFA, with a flex life of ≥1200 cycles and corrosion resistance comparable to F4.
Smooth Operation: Equipped with a screw lift mechanism that provides high torque and stable operation.
Usage Range:Ideal for shutting off the transportation of corrosive media.
Installation and Operation of CPVC Plastic Diaphragm Valve
When connecting the flanges at both ends to the pipeline, tighten the bolts evenly to prevent flange deformation and potential leakage.
Turn the handle clockwise to close the valve and counterclockwise to open it.
The valve's open position can be determined by the indicator.
The diaphragm, made from soft materials such as rubber or plastic, offers excellent sealing performance. As a wear component, it should be replaced periodically based on the properties of the media.
Due to material limitations, diaphragm valves are best suited for low-pressure and relatively low-temperature applications.
Corrosion-resistant plastic diaphragm valves can be categorized by structure type into weir, straight-through, stop, angle, gate, and straight-flow types.
They are typically flange-connected and can be operated manually, electrically, or pneumatically. Pneumatic drive options include normally open, normally closed, and reciprocating types.
Not recommended for use in pipelines with temperatures exceeding 95°C, organic solvents, strong oxidizing agents, or high-pressure applications.
