INTRODUCTION:
The MS4D is a Two Step Solenoid Valve which opens to 10% of the rated flow in the 1st step (soft open) and opens completely in the 2nd step. The type of operation, helps prevent probable liquid hammers in the system. The valve is direct replacement for MS4A valves with better versatility. Due to its special design, this valve can be used to replace dual solenoid systems of Soft-gas and Hot-gas in Hot-Gas defrosting systems with a single valve. It is available in 20-50NB sizes.
