Bryan Donkin: Gas Pressure Regulator with an integral over pressure cut off or OPCO

Featured Product
Bryan Donkin Slam Shut Valves are specifically designed to protect downstream equipment from either under or over pressure conditions.

For instance, a slam shut can be used to mechanically isolate a gas system should the pressure exceed a given value (over pressure cut off or OPCO).

A slam shut can also be used to mechanically shut off a gas system should the pressure fall below a given value which may happen if a gas line is severed (under pressure cut off or UPCO). In addition, slam shuts can be fitted with thermal links that will shut the valve in the case of a fire.

Models 209 and 309 series are available incorporated with many of our pressure regulating valves as an option to enhance the regulators features, or independently mounted on its own body. Use with confidence with natural gas and all other non-corrosive gases.
