Product Description:

Check Valve Manufacturer

Designed for use in the ASME Boiler and Pressure Vessel Code Part I applications, including vents, drains, bypass systems, instrument isolation, control valve isolation, auxiliary steam lines, heat exchangers, and oil and gas applications. It has a reliable sealing ability at both high temperature and high pressure conditions.

Main Features of Check Valve

  • Material advantage: the main material of forged steel check valve is forged steel, which has excellent mechanical properties and corrosion resistance. Forging steel has higher strength and hardness, can withstand higher pressure and temperature, Suitable for high pressure and high temperature working environment.
  • Strong structure: forged steel check valve adopts forging process, the structure is firm, can withstand large pressure impact and vibration, has a long service life. Forging steel check valve has a high sealing performance, Can effectively prevent leakage.
  • Small fluid resistance: the internal flow channel design of the forged steel check valve is reasonable, the channel is smooth, and the resistance of the fluid passing through the valve is small, which can reduce the energy consumption and pressure loss.
  • High reliability: forged steel check valve has rapid, flexible opening and closing characteristics, can quickly close off under reverse pressure, and prevent the reverse flow of fluid. It can effectively protect the pipeline and Equipment, reducing the risk of accidents and damage.
  • Wide range of applications: forged steel check valve is suitable for various fluid media, including liquid, gas and steam. It is widely used in the pipeline system of petroleum, chemical industry, electric power, metallurgy, paper making and other industries.
  • In a word, the forged steel check valve has the characteristics of material advantage, firm structure, small fluid resistance and high reliability. It is suitable for the fluid control system of high pressure, high temperature and corrosive media, and is widely used in the industrial fields.
