Pneumatic Actuator
Double-Acting Pneumatic Actuated Ball Valves
Double-acting uses air to move internal pistons (racks) in two directions, which rotates the actuator pinion 90°. The pinion is connected to the ball valve stem and opens or closes the ball valve as it rotates. Double-acting actuators will return to the normal position when power is lost and can be configured as either normally open or normally closed. In the event that air supply is lost, double-acting actuators will stay in their current position.
Spring-Return Pneumatic Actuated Ball Valves
Spring-return uses air to move the internal pistons in one direction and springs in the other. These actuators are normally supplied as an air to open, spring to close operation, but can be supplied as air to close, spring to open. The mechanical springs can be susceptible to spring fatigue, making double-acting a better choice for high-cycle applications. Spring-return actuators will fail to the normal position in the event of either power failure or loss of air supply.
Double-Acting with Failsafe
Gemini Valve now offers an industry first double-acting pneumatic actuator with failsafe. This combines the durability of a double-acting actuator with the failsafe normally only offered by spring-return models. The actuator operates in a double-acting configuration until power or air pressure is lost, and springs engage automatically to return the valve to the normal position.
