Valve Closing Speed Control Device

The BERMAD Closing Speed Control Device (CSCD) is a valve control accessory, typically installed in the valve control trim and used to adjust the closing speed of BERMAD valves.
The CSCD controls the Main Valve Closing Speed by enabling the adjustment and setting of the water flow rate that is introduced to the BERMAD valve’s control chamber upon a closing command. This allows the operator to either decrease or increase the closing speed of the BERMAD main valve.
Often used for the prevention of pressure surges caused by the quick opening reaction of fire protection valves.
