Product Description

Use of PVDF plastic swing check valve
Swing check valve is suitable for nominal pressure PN1.0MPa~42.0MPa, Class150-2500; Nominal diameter DN15~1200mm, NPS1/2~48; The working temperature of -196~540ºC of various pipes, used to prevent the backflow of the medium. Through the selection of different materials, can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea and other media.
Suitable for clean media, not suitable for media containing solid particles and large viscosity.

PVDF plastic swing check valve structure characteristics
1. The structural length is short, and the structural length is only 1/4 to 1/8 of the traditional flanged check valve
2, small size, light weight, its weight is only 1/4 to 1/20 of the traditional flanged check valve
3, the valve flap closes quickly, and the water hammer pressure is small
4, horizontal or vertical pipe can be used, easy to install
5, the flow channel is unobstructed, the fluid resistance is small
6, sensitive action, good sealing performance
7. Short stroke of valve disc and small impact force of closing valve
8, the overall structure, simple and compact, beautiful shape
9, long service life, high reliability
Check valves can also be used to supply oil to auxiliary systems where the pressure may be higher than the system pressure. Check valves can be divided into swing check valves (which rotate according to the center of gravity) and lift check valves (which move along the axis).
Check valves The role of this type of valve is to allow the medium to flow in only one direction and prevent reverse flow. This type of valve usually works automatically. Under the action of unidirectional flow of fluid pressure, the disc opens; When the fluid flows in reverse, the valve seat is affected by the fluid pressure and the weight of the valve disc, and the flow rate is cut off.
