Product Overview
The H76X check valve is composed of the valve body, valve disc, valve stem and spring, etc., and is connected by flange. Due to the short closing stroke of the valve disc and the spring loading, the water hammer phenomenon can be significantly reduced. This valve is mainly applicable to the water supply and drainage pipelines of cities, industries and high-rise buildings. Because its structural length is shorter than that of ordinary check valves, it is more suitable for places with limited installation space.
Structural Characteristics
- Short length, small volume and light weight of product structure;
- Sealing surface can be selected according to different working conditions soft seal or hard seal material sealing performance;
- The opening pressure is very small, the disc can be fully opened under a very small pressure difference;
- Fast disc closing, low water hammer pressure;
- Horizontal or vertical pipe can be used for easy installation;
- The material of the parts and the form and size of the valve end face can be reasonably selected according to the actual working conditions or the requirements of users. Meet various engineering needs.
