Plastic PVC PVDF PP Pph CPVC UPVC Hand Lever Gear Wheel Weir Diaphragm Valve Butterfly Valve/Flange True Union Ball Valve/Pneumatic Electric Swing Check Valve RPV112 weir diaphragm valve is a classical model, either the design of structure or the work performance is excellent. This model is usually work on larger size pipelines. Brief introduction: The diaphragm valve has a simple structure, small fluid resistance, and larger circulation capacity than other types of valves of the same specification; no leakage, and can be used for high viscosity and suspension particle medium adjustment. The diaphragm separates the medium from the upper cavity of the valve stem, so there is no packing medium and no leakage. Basic specification Size range:DN125~DN250 (5 inch ~ 10 inch) Body materials:PVC-U;PVC-C;PVDF;PP-GF;PP-H Diaphragm material:PTFE with EPDM cushion Flange connection:DIN PN10; ANSI CL150; JIS 10K Design pressure:0.4~0.7Mpa (PN4~PN7 bar) Feature of valve Body and diaphragm that touch medium are made from plastic and rubber. EPDM cushion protect the PTFE diaphragm from over tighten, make sealing better Steel gasket make the bonnet and body bolted stronger and sealing better. Iron disc is strong to make the diaphragm seal with body better. Pneumatic actuator mounting is available.

Fluid control characteristics and shut-off sealing performance. When the butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics. The butterfly valve has two sealing types: elastic seal and metal seal. Basic specification Size: DN50~DN200 (2 inch ~ 8 inch) Body Material: PVC Seal material: EPDM, NBR Wafer connection: DIN PN10; ANSI CL150; JIS 10K Design pressure: 1.0Mpa (PN10 bar) Feature of valve Disc and seat that touch medium are made from plastic and rubber Multi-hole fi t for different standards connection Valve is easy to assemble and disassemble to change damaged parts Electric and pneumatic actuator mounting are available Brief introduction: Ball valve, the opening and closing member is driven by the valve stem and rotated around the axis of the ball valve. It can also be used for fluid adjustment and control, in which the hard sealed V-type ball valve has its V-type ball core and the overlaid welded carbide metal valve seat has a strong shear force, especially suitable for the medium containing fiber, small solid burst material, etc. The multi-pass ball valve can not only flexibly control the flow, diversion and flow direction of the pipeline, but also close either channel and connect the other two channels. These valves shall generally be installed horizontally in pipes. The ball valve is divided into pneumatic ball valve, electric ball valve and manual ball valve. Basic specification Size: 1/2 inch ~ 4 inch Body Material:PVC-U Seal material:EPDM Seat Material:PTFE Socket connection:ANSI Design pr
