Mechanically Actuated Valves

Mechanically actuated valves are often used as "signal valves" and feed back a pneumatic signal to the controller. This feedback, e.g. "End position reached", is realised via a stem actuated valve or roller actuated valve. This is a simple application, but it is an extremely popular solution for smaller machines and conveying systems, e.g. for controlling simple clamping and locking operations in semi-automated assembly and production. The modern design with metal housing combines sturdiness and functionality.

Key Benefits

Air control valves are fundamental components of any pneumatic system. Selecting the right air control valves to regulate system pressure, direction of flow, and rate of flow is crucial when designing fluid power circuitry. If the pneumatic valve is too big for your application, you will be wasting air and money. If it’s too small, the actuator will not function properly.

Key Advantages

Here's a brief list of advantages derived from the use of mechanically actuatedvalves:

  • No electronic controller required
  • No programming effort required
  • Easy to adjust and connect
  • Control and measurement via sensors
  • Variety of porting options
  • Numerous configurations for added versatility
  • Miniature size availability
  • Colored nylon actuators for easy identification
  • Long product life
  • Plated for corrosion resistance

Available Models

5 Way Valves
5-way valves are one of the most commonly used pneumatic components for directional control. By providing four distinct flow paths, these valves make it easy to reverse the motion of a cylinder or motor.
3 Way Normally Open Valves
Primarily used to operate single-acting actuators such as spring-return cylinders, 3-way valves feature three passages within a valve body which are used to pressurise and exhaust a port. AZ Pneumatica manufactures several 3-Way Normally Open valves to fit application requirements.
3 Way Normally Closed Valves
3-Way valves feature three passages within a valve body which are used to pressurise and exhaust a port. These valves are primarily used to operate single-acting actuators such as spring-return cylinders. AZ Pneumatica manufactures a wide variety of 3-Way Normally Closed valves to accommodate application requirements.


The mechanically operated valves in the Series 3 (1/8”) have been designed with three different types of actuation, plunger, lever/roller and unidirectional lever/roller.  In each case, return is effected by a mechanical spring. The Series 3, 3-way/2-position valves are normally closed in the rest position when the pressure is supplied at P and are normally open when the pressure is supplied at the connection R, the user port A remaining unchanged. Moreover, the 5-way/2-position valves may be supplied via the ports R and S with two different pressures if a cylinder has to be operated using a delivery pressure which is different from the return pressure. They can be operated with vacuum down to -.9 bar (28” Hg). Additionally, the series 3 valves can be supplied with 2 different pressures into ports 3 and 5 if a cylinder requires different extend and retract forces. The series 1 valves offer a more rugged, compact design with steel operator interfaces.
