APPLICATIONS

The modular design concept of the MV74MM makes it possible to design and build production systems, brass-board arrangements or test set-ups by using the same valves for each application. The high efficiency of Marotta’s directional control valve allows them to be used in a wide range of applications such as: 

OPERATING DESCRIPTION

In the de-energized position, Port “A” is blocked by the poppet, which is held against the normally closed seat by the poppet return spring. Port “B” is directly open to Port “C”, permitting free flow in either direction.

With voltage applied, the solenoid armature assembly moves the poppet away from the normally closed seat and onto the normally open seat. Now, Port “A” and Port “C” are interconnected and Port “B” is sealed from Port “C”.

The valves are a balanced poppet design, requiring a relatively small solenoid actuator. This feature conserves power and minimizes the space required for installation.
