Check Valve Company

Check valves are employed in wide range of piping used to transport fluids, or keep the gases or fluids in the piping separate. These valves permit the release of content only in one direction. At times it don't have external handle to make them work, they work automatically on the basis on internal pressure.

There are many manufacturing check valves company and offer a several types.

Check Valves are an enormous category and are most frequently used in chemical, water, oil and gas, power, pulp and paper industry. They are also used in fire systems such as dry pipe fire sprinkler systems. In all the applications check valves thwart the backward flow of water or fluids into the piping system.

The most significant criteria to be measured in installing check valves in a piping is the cracking pressure. This is the pressure that opens the valves and thus choosing the right fit it for the piping is crucial. It is used where there is require to:

  • Prevent the reverse flow of contents of fluids or gases present in the pipe system.
  • Shield the other components of pipeline from the damage by blocking any back flow.
  • Thwart the flow because of gravity or pressure variations.

Broadly speaking there is following types of check valves:

Stop C V: This kind of check valve is a designed to cut off the supply of the liquid, water, oil or gas irrespective of the direction of flow. Stop check valve can stop the flow of contents irrespective external pressure.

Ball C V - It has a spherical metallic ball to cut-off the flow. It is used in pipe systems that carry gel or liquid contents. In some designs the ball is made up of ruby.

Lift- C V: The disc in this valve is lifted to facilitate the flow of fluid. The valve closes when the pressure recedes.

Diaphragm C V: This valve has a flexible diaphragm that opens or closes depending upon the flow and pressure in the pipeline
As well the above mentioned types there are a variety of other designs of check valves and each kind gives rise to a different category, for example bulky lift check valves can be replaced with wafer check valves.

Check Valves are an enormous type and are most frequently used in chemical, water, oil and gas, power, pulp and paper industry. They are also used in fire systems such as dry pipe fire sprinkler systems. In all the applications check valves thwart the rearward flow of water or fluids into the piping system.

Uh oh! We couldn't find anything.
