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.

Plastic PVC PVDF PP Pph UPVC Hand Lever Gear Wheel Weir Diaphragm Valve Butterfly Valve/Flange True Union Water Ball Valve/Pneumatic Electric Swing Check ValveBrief 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.

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

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.

FAQ

What materials are used for the valve body and diaphragm?
The valve body and diaphragm are made from plastic and rubber materials such as PVC-U, PVC-C, PVDF, PP-GF, and PP-H. The diaphragm specifically uses PTFE with an EPDM cushion for enhanced sealing.
Can these valves be used for corrosive chemicals?
Yes, these valves are designed with anti-corrosive features. The parts touching the medium are made from plastic and rubber, making them suitable for chemical industrial, chlor-alkali industry, and water treatment applications.
What are the available connection standards?
The valves support multiple flange connection standards including DIN PN10, ANSI CL150, and JIS 10K. Some models also offer socket connections compatible with DIN, ANSI, JIS, and CNS.
Is automation possible for these valves?
Yes, pneumatic and electric actuator mounting are available for both diaphragm and butterfly valves. Manual options include hand lever and gear wheel actuators.
What is the design pressure rating?
The design pressure varies by valve type. Diaphragm valves are rated at 0.4~0.7Mpa (PN4~PN7 bar), while butterfly and ball valves are rated at 1.0Mpa (PN10 bar).
Are these valves suitable for high viscosity media?
Yes, the diaphragm valve design allows for the adjustment of high viscosity and suspension particle mediums without leakage, thanks to the separation of the medium from the valve stem.
What is the typical lead time for orders?
The average lead time is within 15 workdays for both peak season and off-season periods.
