PSRQ641F pneumatic ball valve is a novel pneumatic self-control product carefully manufactured based on the introduction of foreign technology and updated design. Using electromagnetic directional valves or directly configuring springs (single acting spring reset) and 4-7kgf/cm2 air source to control valve angle operation inside the cylinder; 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. This product is divided into metal seals and soft seals based on its sealing performance. It has the characteristics of compact structure, small volume, reliable operation, good sealing, easy maintenance, convenient installation, and strong adaptability. 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.
