Air Operated Valves

Air operated valves, also known as pneumatic piston valves or air operated piston valves are designed to function effectively in a wide range of high demanding industry applications. Often used in applications where there is excess ambient temperature or high-pressure steam duty, air operated valves are multifunctional and can be used with varying media, including: air, water, hydraulic oil and steam.

In order to allow the valves to operate effectively with dangerous media, the piston valve material has to be durable. Air operated valves from MGA Controls are manufactured from only the most hard-wearing and robust material selection, including bronze, brass and stainless steel. These materials are recognised for their ability to operate in hazardous environments without damaging the service life of the valve.

Our range of components, manufactured for compatibility with air operated piston valves also allow the product to be applied to diverse working environments. Components such as the electromagnetic pilot solenoid valve, allow for precise remote control, enhancing the existing features of the air operated valve, ensuring precise and reliable operation at all times.

MGA Controls Ltd are proud to partner with leading manufacturers of piston valves, such as Buschjost – part of the IMI Precision Engineering Group – and Bürkert. Below, we offer more information about the types of air operated valves available from MGA Controls. For more information regarding our range of pneumatic piston valves, please contact the MGA Controls sales team on 01704 898980 or store@mgacontrols.co.uk.


The Type 2000 air operated valve from Bürkert is an externally piloted air operated piston valve, operating with either a single or double–acting piston actuator. High flow rates are achievable thanks to the flow path, which is almost straight and in line with the pipe.

The reliable self–adjusting packing gland provides high sealing integrity, which reduces wear and extends service life. These maintenance-free and robust air operated valves can be retrofitted with a comprehensive range of accessories for position indication, stroke limitation or manual override, or can be fitted with a 3/2-Way Pilot Control Valve for electrical operation.

The 84500 Series Buschjost 2/2-Way piston valve is a brass bodied, pressure operated control valve, suitable for neutral and aggressive liquids and gases including steam.

The 84500 Series air operated valve is fitted with many standard features, including damped closing and visual position indication.
The valve can be actuated using a pilot air supply, or can be combined with the Buschjost 84660 Series 3/2-Way Solenoid Pilot Valve for remote electric operation.
