Product Details
Single acting double acting flange pneumatic O-ring ball valve
Product Overview
Our company produces a dual (single) acting pneumatic piston actuator and a floating ball valve. Also equipped with travel limit switches, solenoid valves, pressure reducing valves, andThe 0.4-0.7MPa air source can achieve switch operation and send two pairs of passive contact signals to indicate the opening and closing of the valve. It is powered by compressed air, and the valve stem drives the valve core to rotate 90 ° inside the valve body to achieve a fully open to fully closed action. According to its sealing performance, it can be divided into soft sealing valve seats and metal sealing valve seats. Soft sealed valve seats are suitable for temperatures ≤ 260 ° C, while metal hard sealed valve seats are suitable for temperatures ≤ 500 ° C. It has the characteristics of compact structure, small size, reliable operation, good sealing, and easy maintenance. Widely used in automatic control systems in industries such as petroleum, chemical, light industry, pharmaceuticals, and papermaking.
