The VM/CP-NC is a Diaphragm Valve, pneumatically actuated, particularly suitable for regulation or on-off operations with dirty or abrasive fluids. The valve is normally closed by the actuator springs, and is opened by the control media. It is operated by an actuator diaphragm type, maintenance free. It can be mounted in any position.
