Description

The Series MD Soft Start Valves help to avoid the sudden movement of pneumatic actuators and have an opening of the main air path at about 50% of the value of the inlet pressure. The blanked connection on the upper side allows either the time increase to fill the system through a small additional volume or the connection of a pressure switch. Switching time can be extended by an upper air intake or a pressure switch may be connected.
These valves also offer a security function to maintain the command sequence, and the time at which the valve reaches 50% of the inlet pressure may also be altered via adjustment of a regulation screw.
