Pneumatic valve actuator VS-092DA-180°

quarter-turn90°180°

pneumatic actuator used, make sure the valve opens, closing torque, and then do the valve using a fluid medium, added security value. For cleaning, lubricating medium increased by 20% Security value; of water vapor and non-lubricating medium security value by 25%; non-lubricated dry gas media to increase 60% security value; non-lubricated gas transmission medium to increase the powder particles 100% security value. Then the gas supply pressure of work, find the double-action or single-acting output torque table, available and accurate actuator signal. Single-acting torque Table, the minimum time to close the valve spring torque is the torque, maximum torque is to open the valve spring torque. Two additional pistons make a third (intermediate) position possible. The intermediate position is exactly reproducible. To use for multiple-way valves and pig valves. Safety function with spring-centered central position pneumatic twin piston actuator, single-acting and double-acting version with two additional pistons, pivoting angle 90°+ 90° (180°) respectively 120°+ 120° (240°) valve combinations (preferably 3/2-way) corresponding safety conception respectively requirements. 1, the pneumatic actuator can be directly connected with the valve, brackets and fittings can also be connected with the valve installation. Fasteners must not loose connection. 2, to ensure that the actuator output shaft coaxial with the valve stem is installed, and turn the flexible non-crawling phenomenon. 3, connecting pipes, fittings, accessories, etc. should be clean.
