Overview of H71W type clamp check valve:

The H71W stainless steel clamp check valve adopts a new type of material and is made of corrosion-resistant stainless steel. It can be installed on any position of the pipeline to prevent backflow of the medium and backflow of the boiler feedwater system. The connection method is to use the existing flange clamps at both ends of the pipeline to put it into operation. Its various indicators are superior to any type of return valve currently available on the market. It is widely used in water supply and drainage, fire protection, construction, HVAC, and industrial systems. Any medium such as water, gas, oil, acid, alkali solution, hydrogen, ammonia, special fire-fighting pipelines, etc. can be used. For example, it can be installed at the outlet of the water pump, which can avoid water hammer, water hammer sound and destructive impact, achieve the purpose of preventing backflow and protecting equipment, and have a good energy-saving effect.

Characteristics of H71W clamp check valve:

The valve disc stroke of the clamp check valve is short, the valve disc is lightweight, has spring assisted closing, and the closing speed is fast. The structure has the characteristics of short length, small volume, light weight, low fluid resistance, reliable sealing, smooth opening and closing, wear resistance, long service life, oil pressure and slow closing not affected by the medium, and good energy-saving effect. It brings great convenience to the installation, handling, storage and pipeline layout of valves, and can save a lot of materials and reduce costs.

Purpose:

Check valves are used in pipeline systems to prevent reverse flow of media, reverse rotation of pumps and their drive motors, and release of media from containers. Check valves can also be used on pipelines to supply auxiliary systems where the pressure may rise above the main system pressure. Check valves can be applied to pipelines with various media depending on the material. A check valve installed on a pipeline becomes one of the fluid components of the complete pipeline, and its valve disc opening and closing process is affected by the transient flow state of the system it is in; Conversely, the closing characteristics of the valve disc have an effect on the fluid flow state
