The pneumatic diaphragm valve has undergone a sophisticated inspection procedure and strict quality management. During the processing, the flow channel is precisely polished and sterilized. The sealing ring is fully enclosed and tightly wraps the valve ball, without gaps and dead angles. The two ends are connected with clamps for easy disassembly, cleaning and maintenance. The working principle of the diaphragm valve is also to drive the ball to rotate through the 90-degree rotation of the pneumatic actuator to achieve the circulation and isolation of the medium. The new EPDM polymer of the improved EPDM adopts high-strength braided material to ensure strong strength and durability. The use of vulcanization technology increases the service life and bending times when used in steam.
