Specifications
Wafer type butterfly check valve is small volume, light weight, compact structure, convenient maintenance
Our product- carbon steel wafer check valve consist of valve body,disk,valve rod,spring and other parts, adapted wafer connection.
Its description:
1,Due to disk's short closing stroke,and spring equipped,it can reduce water hammer effectively.This valve is mainly suitable for water supply and drain pipeline of urban, industry and high-rise building .
2,Because of shorter structural length than average check valve,it is well suited to limited space.
3,It is used to prevent reverse flow of medium in puring pipeline, industry, environmental protection, water treatmentand high-rise building's water supply and drainage.
Benefits and Features:
1, Wafer type check valve is small volume, light weight, compact structure, convenient maintenance
2, the valve plate use dual type which can be closed automatically for its spring of the elastic forcemoment
3, It can prevent the backflow of medium for its for quick closing function
4, body structure length is short, and also has good rigidity
5, It is safe and convenient, and can be used for both horizontal and vertical installation.
Standards:
1, flange connection dimension: GB/T1724.1-98, ANSI 150/250/300 lbs, BS PN10, JIS 10K are also available upon request.
2, structural length: GB/T12221-1989, ISO5752-82.
