LINEAR AND DIAPHRAGM ACTUATORS |
| |
|
Linear actuators are coupled with gate, globe, and knife edge gate valves, etc., all of which have linear operation. |
Diaphragm actuators are used for control valve applications due to high positioning speed, faster response time, and improved reliability.

CONTROLS AND ACCESSORIES
|
| |
- Limit switches: for remote position indication and sequencing
- Solenoid valves: for remote electrical actuation
- Positioners: to ensure accurate and stable control valve positioning
- Air filter and regulator: for supplying pneumatic control equipment with clean dry air at a constant pressure
- Quick exhaust valve: for fast operation of actuators
- Speed and flow control valve: to throttle the air flow to and from the actuator to meet the operational characteristics of the system
- Air lock valve: for achieving stay put action in case of air failure
- Check valves and shuttle valves: to allow flow in only one direction or to divert flow to another direction
- Volume tank: pneumatic fail safe and local operation for double acting actuators and local emergency operation for spring return actuator
