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.

Brief introduction:
The butterfly valve has the characteristics of simple structure, small volume, light weight, material consumption, small installation size, rapid switch, 90° reciprocating rotation, small driving torque, etc. It is used to cut off, connect and adjust the medium in the pipeline. 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 pressure:1.0Mpa(PN10 bar)
Feature of valve
All the parts that will touch medium is made from plastic and rubber.
Self sealing ball design make valve sealing better
Flange end is optional.
Actuator mounting plate available
Brief introduction:
Check valve refers to a valve with a circular valve valve and by its own weight and medium pressure action to block the backflow of the medium. Belongs to the automatic valve class, also known as the reverse check valve, check valve, return valve or isolation valve.
Basic specification
Size: DN15~DN50 (1/2 inch ~ 2 inch)
Body Material: PVC-U;PVC-C;PP-H
Seal material: EPDM
Socket connection: DIN,ANSI,JIS,CNS
Design pressure: 1.0Mpa(PN10 bar)
Feature of valve
Ball orbital design lower the valve leaking risk.
Double union design easy to replace and install of valves
Hollow ball design make the valve seal better
Simple structure make it easy to diagnose problem and repair valve
Flange end is optional.
