Product Details
High pressure internal thread pneumatic ball valveProduct Introduction
The QJ (D/S) RG type precision small pneumatic high-pressure O-type ball valve is a ball valve with a 90 ° angle. The valve body adopts a three open (three body) flange connection ball valve, and the ball core adopts a fixed structure, requiring low operating torque. The PTFE valve seat adopts a floating embedded structure, with excellent sealing performance. The actuator adopts ZGH and ZGQ high-performance cylinder piston actuators, with simple structure and large output torque. This ball valve is suitable for controlling high-pressure or high-pressure differential fluids containing fibers and fixed particles. The double acting pneumatic high-pressure O-type ball valve model is QJSRG-160/320, and the single acting pneumatic high-pressure O-type ball valve model is QJDRG-160/320.
