Plastic diaphragm valves, manufactured from hard-wearing plastic materials, are designed to be resistant to abrasion and clogging. Plastic diaphragm check valves can be used in applications where blockages may otherwise occur. However, the linear design of the component allows a streamlined flow of media. Durapipe are leading manufacturers of plastic diaphragm valves, with two core product series: Dialock and VM.
Plastic diaphragm check valves are a top end design, often used in throttling, maintenance and on/off service applications. Plastic diaphragm valves are used in a wide range of applications, ranging from water treatment to chemical abrasion processes. Their application uses will most likely depend on seal and body material composition.
Operated either manually, electrically or pneumatically, plastic diaphragm valves are commonly associated with 2-way solenoid valves and generally consist of a rubber diaphragm that moves up and down in a valve body. Thanks to their linear design, plastic diaphragm check valves offer significantly increased flow rates.
Common material selections include PVC, PTFE and EPDM. EPDM diaphragms will be used in applications where chemical resistance is a necessity, PVC diaphragm valves may be utilised in wastewater applications. It is important to check material properties before utilising the plastic in order to ensure the suitability and longevity of your diaphragm valve.
