Low Pressure Pneumatic Actuator (Series L)

The Series L “low pressure” pneumatic actuator features an aluminum housing that accepts a 20-25 psig supply to operate.

The nominal 8-13 psi spring range allows the piston to extend while the swivel connection provides non-binding movement.

A pilot positioner can also be ordered giving the actuator an adjustable 3-13 psi span for accurate proportional control.

Each version is inherently spring return when loss of air pressure occurs making these an economical solution for fail-safe commercial valve automation.
