MAC Valves, directional control valves, poppet valves, ISO valves, 3-way valves, 4-way valves, bullet valves, proportional pressure controller MAC home page MAC air valves are available in a wide range of flow and package configurations. Single inline or manifold assemblies with optional fieldbus interfaces. MAC valves are designed for high reliabilty and high performance requirements 

MAC's direct acting valve models can handle vacuum pressures to 120 psi and can be operated as a normally open, normally closed, two or three way, selector or diverter allowing the valve to be used in a variety of applications and reducing the need to stock multiple valves. The Balanced design produces precise repeatability regardless of inlet pressure fluctuations - giving consistent machine performance regardless of plant environment.

Proportional Pressure ControlsMAC Proportional Pressure Controller

The MAC Proportional Pressure Controller, (PPC) is an innovative product which converts an electrical signal into a proportional pneumatic output.

The key to the MAC PPCs are two MAC 34, 45, 400, 47, 92 or 93 Series valves that are used to control the  output pressure. The valves are operated by the PPCs closed loop electronic control circuit. Feedback is obtained from one or two transducers. The balanced poppet, fast response, and high flow of these two MAC Valves  provide outstanding performance characteristics for the PPC.
