DA/SR Series pneumatic actuator

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

4. blow-out proof design

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.
