Fisher™ P600 Series Actuators For Internal Valves
PROD_FREG_P613
All Fisher 1-1/4, 2 and 3-inch threaded NPT, & 3 and 4-inch single and double flanged internal valves can be fitted with a pneumatic actuator that can be used to open and close the internal valves from a remote location.
Use of pneumatic actuators permits the opening and closing of the internal valve to be tied into the air brake of the transport or bobtail. Pneumatic Actuators can also provide a convenient way to remotely operate internal valves on stationary storage tanks at bulk plants.
