Supplier: ControlAir Inc.
Description: The ControlAir Type 250 Lockup Air Relay is a reliable unit for fail in place applications of control valves when air supply drops below acceptable pressure levels. Valve or damper position is maintained by capturing air pressure inside the diaphragm chamber (or piston cylinder) of the actuator
- Type: Air Lock Relay
- Body Material: Aluminum, Stainless Steel
Supplier: OMEGA Engineering, Inc.
Description: A “current to pressure” converter (I/P) converts an analog signal (4 to 20 mA) to a proportional linear pneumatic output (3 to 15 psig). Its purpose is to translate the analog output from a control system into a precise, repeatable pressure value to control pneumatic actuators/operators
- Control Input: Current Control
- Connection / Pipe Size: 1/4" NPT
- Body Material: Zinc
Description: Used to manually position a remote damper actuator or reset setpoint of pneumatic controller Airflow Usage 0.022 scfm (9.8 mL/s) Capacity (Cv) 0.021 scfm (9.4 mL/s) below minimum position. Above minimum position, device feeding pilot determines capacity Air connections Barb fittings 5/32 in. (4 mm

Precision Electric Actuators...Reduce Emissions
Beck Drives These precision electric actuators for dampers and valves, reduce NOx emmissions. In 1996, EPRI embarked on a control upgrade project that included the replacement of Kingston's Unit #9 pneumatic actuators with Beck drives on all the boiler dampers and burner tilts mechanisms. The results were astounding. EPRI atrributes two thirds of the significant improvements in NOx emissions directly to the Beck drives. No SCRs, separated over-fire air(SOFA), or low-NOx burners were used. Some... (read more)

The FieldQ actuator is an integrated concept for the automation of quarter turn valves, dampers or other quarter turn applications. It consists of three basic parts: 1) Pneumatic Actuator, 2) Pneumatic Module or NAMUR Plate, and 3) Control Module. FieldQ Pneumatic Actuators must be isolated both
Improving Control: The Issues of Final Control Element Actuation
pneumatic and electric actuators can create problems. A common source of significant pneumatic actuator dead time is sticking due to friction (stiction). This causes stick-slip response, and that occurs as a pneumatic actuator builds air pressure to overcome the static frictional valve load to initiate
