Cast iron check valve: Cast iron check valve construction characteristics

Release Time:

Sep 22,2020

Cast iron check valve is to automatically open and close the piston valve with the help of the material's own flow, with the help of the piston valve's own weight and liquid pressure difference to complete the automatic block liquid material countercurrent gate valve, also known as reverse valve, this product, reverse valve, and back pressure valve.

Cast iron check valve product description:

Cast iron check valves are fully automatic gate valves whose key function is to avoid material backflow, to avoid the reversal of pump and driver motors, and to avoid the release of material in the vessel. The check valve can also be used to supplement ducts in which the operating pressure is likely to rise beyond the system software pressure.

Application scope of cast iron check valve:

Lofted flange lifting mechanism check valve is applicable to pound class PN1.5Mpa, operating temperature -29 ~ 550℃ of crude oil, chemical plants, power plants and other kinds of medium and caliber pipelines under a variety of working pressure, temperature and material control access or disconnect pipeline material opening and closing equipment. Available substances are: water, refined oil, steam, etc.

Cast iron check valve structure features:

1. Cast iron check valve design products production and manufacturing according to GB/T12235 design program production and manufacturing testing, reliable sealing, high quality characteristics.

2. The piston valve and high pressure gate valve are made of Stellite cobalt-based carbide tool spray welding, with good abrasion resistance, heat resistance, abrasion resistance and long service life.

3. Cast iron check valve can choose a variety of pipe flange standards and flange surface forms, considering a variety of engineering projects must and customer requirements.

4. Cast iron check valve body material variety is complete, filling material, gasket according to the specific working conditions or customer regulations can be effectively installed, can apply to a variety of working pressure, temperature and material working conditions.

5. Cast iron check valves can be manufactured according to customer requirements of different structural forms and connection modes of check valves, for a variety of machine equipment supporting facilities.
