Fast acting Actuated Ball Valve

Actuated Ball Valve DN100 Stainless with Fast Open/Close time

 We had contact with our customer through our webchat with the enquiry below:

"I am looking for a 4" pneumatically actuated 1/4 turn ball valve, rated to 20 to 25 bar but which can handle low vacuum at ~0.1 to 1 mbar. with an operating time of 0.5 Seconds"

This valve is to be used in a rocket test fire system.

After many negotiations with various manufacturers we came up with a solution with a 4" BSP 3 Piece Stainless Steel Full Bore Ball Valve fitted with a modified Double Acting Pneumatic Actuator to allow opening and closing time <0.5 seconds.

Our actuator manufacture used 1/2" BSP pilot air connections and increased the orifice size of these ports, that allowed the required the air flow to operate the valve at the required speed.

Below are videos showing the operating of the open cycle and close cycle.
