ZSJQPneumatic cut-off two-way ball valve is a kind of rotary cut-off ball valve, which is the executive unit in the combination instrument of pneumatic or electric unit, and is generally used in combination with solenoid valve and other components. There are two kinds of sealing forms: soft sealing and hard sealing, which are used under the working conditions of - 40 ℃ - 180 ℃ and - 60 ℃ - 450 ℃. The O-type cut-off ball valve adopts piston type pneumatic actuator or electric actuator. The spherical surface of O-type cut-off ball valve is hardened by special process to make its surface smooth and wear-resistant. The valve seat and sealing material are made of high-temperature and wear-resistant carbon fiber materials, and the product structure is exquisite and reasonable. This series of products have the characteristics of high rotating efficiency, large thrust, good sealing, large rated flow coefficient and good interchangeability of parts. This series of products are widely used in oil, chemical, pharmaceutical, metallurgy, textile, paper, sewage treatment and other production departments of gas, liquid transmission pipeline medium cut or open, to meet the requirements of working conditions.
