Product Name:Plastic PVC PP Pph PVDF CPVC UPVC Flange Foot Valve/Gate Valve/Globe Valve/Safety Valve/Pressure Reduce Valve/Air Vent Valve Pn10 Pn16 BS Cns ANSI Cl150 DIN JIS
Brief Introduction:
The bottom valve is also called the reverse check valve, is a low pressure plate valve, its function is to ensure the one-way flow of liquid in the suction pipeline, so that the pump normal work when the pump for a short time to stop work, so that the liquid can not return to the water box, to ensure that the suction pipe is filled with liquid, in order to facilitate the start of the pump.
Basic specification

Feature of valve
All the parts that will touch medium is made from thermo plastic.
One piece body design reduce the leaking risk.
Strong body design extend the service life of valve.

Brief Introduction:
The breathing valve is composed of pressure valve and vacuum valve, which is installed on the ventilation pipe of the cargo tank. It can automatically open and close with the positive and negative pressure of oil and gas in the cargo tank, so that the pressure difference inside and outside the cargo tank remains within the allowable value range.
Dimension
Brief Introduction:
Globe Valve is the most widely used valve, it is widely popular, is because of the process of opening and closing between the sealing surface friction is small, more durable, opening height is not large, easy to manufacture, convenient maintenance, not only suitable for medium and low pressure, but also suitable for high pressure. The closing principle of the stop valve is to rely on the valve bar pressure, to make the valve flap sealing surface and the valve seat sealing surface closely fit, to prevent the flow of the medium.
Basic specification
Size: DN15~DN200 (1/2 inch ~ 8 inch)
Flange connection: DIN PN10
Body Material: PVC-U
Seal material: PTFE
Design pressure: 1.0Mpa (PN10 bar)
Feature of valve
All the parts that will touch medium is made from plastic.
Face to face dimension is equivalent to most commonly used metallic valves, convenient for replacement.
The part of stem which will touch liquid is coated with plastic.
PTFE packing prevent leaking to atmosphere.
Dimension
Brief Introduction:
Gate valve is an opening and closing gate plate, the movement direction of the gate plate is perpendicular to the fluid direction, the gate valve can only be fully open and fully closed, the uncomfortable door parameters vary, usually for 5, the medium temperature is not high for 2 52 '. Improve its process to make up for the deviation in the Angle of the sealing surface process, this brake is called elastic brake.
Basic specification
Size:DN25~DN150 (1 inch ~6 inch)
Body Material: PVC
Seal material:EPDM
Plate:PVC , SS304
Socket connection:DIN ANSI
Feature of valve
All the parts that will touch medium is made from plastic and stainless steel.
Self sealing design make valve sealing better
Flange end is optional.
Dimension
Brief Introduction:
The back pressure valve operates through the elastic force of the built-in spring: when the system pressure ratio is small, the diaphragm blocks the pipe under the spring elastic force; When the system pressure is larger, the diaphragm compression spring, the line is connected, and the liquid passes through the back pressure valve.
Product Features of Back Pressure Valve:
1, Compact structure and stable performance
2, Easy installation and debugging
3, Sensitive reaction and good reproducibility
4, Selective large size range DN10mm DN100mm
5, Small pressure difference by specially designed flow structure to avoid forming a closure
6, Easy to set the working pressure by regulating device
7, Installed in the bypassas overflow valve use
8, Used as anti siphon valve to prevent gravity under static conditions.
