      1. Overview

      The most large quantity decides the pressure 8Bar standard operating temperature scope -20 ℃ ~ +85 ℃ high temperatures: -20 ℃ ~ +,150 ℃, low temperature: -40 ℃ ~ +85 ℃ 90°±5° travelling schedules 100% leaves the plant the test.

      2. Exterior joint

      Conforms to Namur Norm standard appendix joint side
      Conforms to Namur Norm standard solenoid valve connection
      Conforms to ISO5210-DIN3337 standard base valve joint way

      3. Components

      No. Name Description
      Spring Concentric telescoped spring cartridge.The standard bonderizing, high elastic and the reliability, may adapt different barometric pressure and torque, the safe long bolt, when the guarantee service safely disassembles and assembles, the DA/SR series external dimensions is same.
      End Cap High strength epoxy resin coated. Nickel plating is available on request for anti-corrosion.
      Piston Nickel-plate according to the demand
      Screw Standard stainless steel screw
      Cylinder The cylinder body uses the UNI6060 compression casting aluminum alloy. The standard anode hardening polishes processing, extremely good resistance to wear, corrosion resistance,high-tech plates the hole craft enable the air cylinder to have lowly wears the high life, may choose the nickel plating or spread excels in the epoxy resin paint.
      Pinion The standard product for the superficial nickel plating anticorrosion, the anticorrosion uses the stainless steel, guards against the break design.
      Seal Standard type: NBR
      High temperature: VITON
      Low temperature: HNBR
      POM guide ring The contacted area is big, the application material does not need to refuel, the long life.

      5. Installment diversification

      6. Main Technical Data

      Note: Above the parameter in 0.6 MPa pressure, has not matched the approximate time which the valve in the situation obtains.

      7. Air consumption

      8. Weight

      9. DA series double-acting actuator

      On the chart schematic drawing indicated that, the double-acting implementing agency torque rating throughout maintains in the entire travelling schedule process constantly.

      The user may act according to its specific request, refers to following content designation appropriate implementing agency model:

      1). Is clear about operates the valve the greatest torque rating.

      2). the torque rating enlarges 25%-50% hypothesis safety coefficient.(Specifically regards the torque rating which valve type and processing craft)

      3. the basis provides, the reference torque table and the corresponding barometric pressure value, obtains the torque rating should be equal to or surpass the torque rating which provides. 4th, the torque rating determined after, searches the corresponding model then.

       10. SR series single-acting actuator

       On the chart schematic drawing indicated that, the spring repositions the type implementing agency the torque is not constant invariable but gradually reduces. The main reason lies in the spring to compress in the air travelling schedule stage because of the piston motion, the energy which simultaneously accumulates in the movement switching process to which unceasingly decreases progressively the way obtains.

      A) Air travelling

      Opens posture MAD: Under the spring release condition implementing agency torque ties board MAC: Under spring compression condition implementing agency torque.

      B) Spring travelling

      Starts /MMC: The spring compresses when the torque finished /MMD:

      The spring releases when torque. The user may act according to its specific request, refers to following content designation appropriate implementing agency model:

      1st, is clear about operates the valve the greatest torque rating. 2nd, the torque rating enlarges 25%-50% hypothesis safety coefficient. (Specifically regards the torque rating which valve type and processing craft) 3, the basis provides, the reference torque table and the corresponding barometric pressure value, unifies MMD and the MAC minimum value, obtains the torque rating should be equal to or surpass the torque rating which provides. 4th, the torque rating determined after, searches the corresponding model then.
