Electrical Type Pump Control Valve- A76D
Description:
A7MD is a mechnical type pump control valve.
When pump starts, A7MD will open slowly by the pressure increased in the middle chamber which provide a less headloss.
When the pump stops or out of electricirty, A7MD will act like a check valve. It will block the 80% of the flow area quickly and closed slowly at the last 20% stroke. This will prevent water hammer and water slamming.
