Products / Solenoid Valves

Principles of operation

These valves are for Ammonia duty. The MSVA are pilot operated valves whilst the MDSVA are direct operated solenoid valves.

They are used in many applications such as cold stores, freezers, chilling applications etc.

Application

These valves must be installed in horizontal positions with the coil housing no more than 45 degrees from the vertical position.

Construction

The valve is made up from various metals. Whilst stainless stee is used for components like stems, plungers, the main body is made from CI/WCB.
