Q647FPneumatic fixed ball valve

Q647F/HThe fixed pneumatic ball valve is a product that has been updated in design and carefully manufactured based on the introduction of technology. Adopting electromagnetic commutation or directly configuring springs inside the cylinder (single acting spring reset) and0.4~0.7MpaThe valve angle can be controlled by the gas source;

I. Overview

Q647F/HtypePneumatic fixed ball valveIt adopts electromagnetic commutation or directly installs springs (single acting spring reset) in the cylinder0.4~0.7MpaThe 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 body90At ℃, it can achieve full open - full open corner function. Its sphere is fixed and does not move when compressed; Fixed ball valves are equipped with floating valve seats. When subjected to medium pressure, the valve seat moves, causing the sealing ring to press tightly against the ball to ensure sealing; Usually equipped with bearings on the upper and lower shafts of the sphere, with small operating torque, suitable for high-pressure and large-diameter valves; In order to reduce the operating torque of pneumatic ball valves and increase the reliability of sealing, oil sealed ball valves have emerged in recent years. They inject special lubricating oil between the sealing surfaces to form an oil film, which enhances sealing performance and reduces operating torque, making them more suitable for high-pressure and large-diameter ball valves;

This product is divided into metal seal and soft seal according to its sealing performance; It has the characteristics of compact structure, reliable operation, good sealing, easy maintenance, convenient installation, and strong adaptability. 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.
