APPLICATION

SV-4PC series is a sanitary stainless steel diaphragm valve with pneumatic actuator and clamp connections. 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 diaphragm valve operates pneumatically via plastic or ss actuator.
