The MK/NC is a Diaphragm Valve, pneumatically actuated, particularly suitable for regulation or on-off operations with dirty or abrasive fluids, equipped with a maintenance free actuator, piston type, which can be operated with any inert liquid or gas.
The valve is normally closed (NC) by the actuator springs, and is opened by the control media and It can be mounted in any position. Water hammer risk is reduced with this valve.
Utilising the various available body and diaphragm combinations, the valve has a wide range of applications.
The special lubrication system of the actuator allows over 106 duty cycles.
