MILWAUKEE VALVE MC34S5 Pneumatic Actuator, Spring Return

Milwaukee Valve MC34S5 pneumatic actuator operates via pressurised air for controlling valve functions. This high-temperature actuator is used for pharmaceutical, food & beverage, oil & gas, refining, marine and chemical processing applications.

Features:

• It has an improved thrust bearing design that limits friction between the actuator body and pinion, maximises durability by absorbing side-load forces and extends the performance of the pinion O-rings.
• It has superior teeth engagement (during the stroke) to provide consistent torque output and accuracy.

Frequently Asked Questions:

Q. What is the difference between a spring return and a double-acting actuator?

A.

• A spring actuator provides power via spring force that aids in displacing air or liquid in one direction to push / pull the piston. This action controls the valve functions (open / close).
• A double-acting actuator acts in both directions and has ports to displace air or liquid for opening / closing the valve.

Q. What is the fail-safe design of a pneumatic actuator?

A. The spring-return actuator features a fail-safe design that allows it to return to a pre-set home position when power is removed from the actuator.

Q. What is the purpose of adding a spring to the control valve?

A. A spring is placed around the stem of a valve to control the entire valve train, ensuring that the proper amount of spring pressure is applied consistently. This prevents valve bounce during operation.
