Diaphragm valves offer many combinations of body materials and elastomeric diaphragm materials. The valve design is abrasion-resistant and non-clogging. When the diaphragm, which is connected to the stem of the valve by a compressor, is pulled away from the bottom of the valve body or weir, the path of the fluid has a smooth, streamlined flow. Slurries at low pressure, which would normally clog most other valve designs, easily pass through a diaphragm valve. The valve has a top-entry design, allowing in-line maintenance; it is suitable for throttling and on/off service in applications ranging from water treatment to chemical abrasion processes. Diaphragm valves are operated manually, electrically or pneumatically.
| Flanged face-to-face dimensions are equivalent to those of Type G diaphragm valves Rugged body and bonnet are of solid thermoplastic for maximum corrosion resistance Bubble-tight sealing, even in applications such as slurries or suspended particles Weir design for excellent throttling Uniquely designed body and bonnet together with diaphragms of new sealing designs by the state-of-the-art computer aided analysis for superior sealing Bonnet seals to protect internals from corrosive environments Built-in travel stop to prevent diaphragm from being over-tightened Indicator at the top for valve position and prevention of over-tightening All valves with Teflon diaphragms come with PVDF gas barrier, which protects the EPDM backing from gas permeation
| Sizes: 5" - 6" Body Materials: PVC, PP and PVDF Bonnet Materials: PVC, PP, PPG and PVDF Diaphragms: EPDM and PTFE Also available in other materials such as nitrile and FKM
