Double Acting Pneumatic Ball Valve

Double Acting Pneumatic Ball Valve

Double Acting – Actuators in a double acting configuration have air/liquid supplied to both sides of the piston, with one side being higher pressure which achieves the movement required to actuate the valve. This configuration uses the air/liquid as energy to both open and close the valve.

Product Details

At a basic level, an actuator is a control mechanism that is operated by an energy source. This energy can be hydraulic pressure, pneumatic pressure, or electric current which moves the internal mechanical parts of the actuator.They can be designed to fail-open (in the case of actuator failure, the valve will stay open) or fail-close (in the case of actuator failure, the valve will stay closed). They also are distinguished by whether they are for quarter-turn (e.g., ball valves, plug valves) or linear (e.g., gate valves) valve operation.

Double Acting – Actuators in a double acting configuration have air/liquid supplied to both sides of the piston, with one side being higher pressure which achieves the movement required to actuate the valve. This configuration uses the air/liquid as energy to both open and close the valve.

Spring Return – Actuators in a spring return configuration have air/liquid supplied to only one side of the piston, and the energy to move the mechanisms comes from a spring on the opposite side. This configuration uses the air/liquid as energy to open or close the valve, while the spring acts to affect the opposite motion
