APPLICATION
SV-4PC-PS series is a sanitary pneumatic diaphragm valve with tri-clamp ends and Proximity Switches. The valve is excellent for flow control as well as for open/close duties. It is mainly used for sampling, biological system, laboratory engineering, etc. SV-4PC-PS diaphragm valve operates pneumatically via plastic or ss actuator.
