CHV150-300
As the names implies, this valve features a swinging gate that is hinged at the top and opens as a fluid passes through it. A smooth flow passage is provided by the swing check valve when the valve disc is in the fully open position. Within the valve, this smooth channel generates low turbulence and pressure decrease. For the valve to work perfectly, there must always be a minimum pressure to open the disc. When the fluid flow reverses, the pressure and weight of the medium against the disc pushes the disc into the seat, thus preventing all backflow. Check valves are typically considered as safety or protective devices.
Class 150-300 Cast Steel Check Valve is a check valve made of cast steel. It is divided into class 150 and class 300 according to the pressure class. Its features include simple structure, small size, light weight, good sealing performance, and easy operation. This valve is suitable for high-pressure and high-temperature environments to prevent reverse flow of fluid in pipelines. It is usually used in pipeline systems in industrial fields such as petroleum, chemical industry, and electric power.
It is a valve that uses rotary operation to control fluid flow. It usually consists of a valve body, valve cover, valve disc, valve stem, and operating device. This type of valve achieves the flow of medium to open or close by rotating the valve disc, and has good sealing performance, which can effectively prevent medium leakage.
