To get effective use out of the pneumatic cylinders or actuators, use of an appropriate valve system interfaces the pneumatic system with the plant control scheme, such as SCADA. The Valve systems can be combined to perform complicated functions such as, sequential operation of cylinders, interlocking of machine movements, controlling the application of force and ensuring fail-safe operation using discrete logic or integrated controllers.

 

Valves can be individual units or they can be combined into valve islands for simplified installation and communication using all standard BUS protocols.

All our pneumatic valves can be supplied in various materials such as brass, aluminium and stainless steal, including specialist materials for high temperature’s or for severe operating conditions. We can offer a range of sizes from 1/8″ – 2″, including larger sizes for applications requiring more flow or for moving large cylinders.

MGA Controls offers various accessories such as sandwich regulators, flow regulators, check valves, shuttle valves, silencers, pneumatic timers, pneumatic logic and fittings and tubings.

Valve islands


Combining valve functions within a manifold or island offers several advantages:
Much more compact in volume, requiring less space in crowded control cabinets.
Different functions and sizes of valves can be combined together with reduced piping needed as the inlet and exhaust are common across all valves.
Reduced wiring time because many valve modules are designed to make the electrical connections when mechanically connected to other modules thus not requiring individual interconnects to coils or terminal rails.
Combining the wiring within the manifold enables further control functions to be achieved through inbuilt programmable controllers or externally through the digital bus protocols.

Fieldbus capable


MGA Controls can supply a variety of Valve Islands to suit all common bus protocols, including Fieldbus, Profibus, DP, ASI, and many others. We also offer the design and build of pneumatic or electro-pneumatic control panels.
