Overview

The Q641F/H pneumatic cut-off ball valve is a product that has been updated and carefully manufactured based on the introduction of technology. It is the best alternative to the pneumatic cut-off valve used in old industries. By using electromagnetic commutation or directly configuring a spring (single acting spring reset) and a 0.4~0.7Mpa air source in the AW large cylinder, the valve angle operation can be controlled; Powered by compressed air, the valve stem drives the valve core to rotate 90 ℃ inside the valve body, achieving a fully open to fully open angle function.

Q641FPneumatic cut-off ball valve

Q641F/HtypePneumatic cut-off ball valveIt is a product that is updated in design and carefully manufactured based on the introduction of technology,It is the best substitute for pneumatic globe valves used in old industries. Using electromagnetic commutation or directly inAWSpring configuration inside the atmospheric cylinder (single acting spring reset) and0.4~0.7MpaThe valve angle can be controlled by the gas source; Powered by compressed air, the valve stem drives the valve core to rotate inside the valve body90℃, can achieve full opening——Fully open corner function.

Products are divided into metal seals and soft seals based on their sealing performance. It has the characteristics of compact structure, small volume, reliable operation, good sealing, easy maintenance, convenient installation, and strong adaptability. Especially suitable for situations where the medium is viscous, contains particles, and has fibrous properties. It can be widely used in automatic control systems for industries such as petroleum, chemical, teaching equipment, light industry, high-voltage equipment, pharmaceuticals, papermaking, etc., for remote centralized control or on-site control.
