Bettis G-Series Pneumatic Valve Actuator. . Double-acting actuators have air or liquid supplied to both sides of the piston with one side at higher pressure, which achieves the movement required to actuate the valve. Connection ports positioned near both ends allow the piston rod to move both forwards and backwards. When the General Information Technical Information. What is Sigle Acting Actuator & Double Acting Actuator #Application Tips 1 StephenMFG@gmail.com However, if you have the choice between a single and double acting cylinder, here are a few reasons why you should always choose the double cylinder: Pneumatic Actuator. Single-Acting vs. Double-Acting Valve Actuators - Gemini Valve The extra port also allows more control of the plunger during retraction and ensures it always returns back to its starting point. These valves are also known as cartridge valves, and they screw into your mounting block. The Double-Acting Actuator (TL) block represents a linear actuator with piston motion controlled by two opposing thermal liquid chambers. Compact design and cost-effective Scotch Yoke pneumatic actuator with single acting . Double Acting Pneumatic Operator. Short stroke cylinders: Our range of short stroke cylinders come as either single or double-acting. Single-ended and double-ended cylinders are used to deliver high performance and work output, but the latter can be more expensive than the former. Search Clear. The Bettis G-Series pneumatic, scotch yoke, valve actuator is a highly unique and reliable actuator for operating ball, butterfly or plug valves along with louvers, dampers and other 90 degree rotating mechanisms. The double-acting actuator only uses one piston as an element to operate the valve, therefore, the actuator must be pressurized alternately from both sides. This model operates on 60-120 PSI air supply. This One is spring return type (also call single acting), and the other is double-acting type . What is Double Acting Actuator? For technical drawings and 3-D models, click on a part number. rotary for aircraft double-acting. A double acting cylinder is actually used in more applications than a single acting cylinder.
