Reliability and versatility with the FEX Series Direct-acting Regulators

The FEX series of two stage direct-acting spring loaded regulators are widely used in both civil and industrial installations using natural gas, LPG and other non corrosive gases. They are designed for direct installation to a gas meter and for use in general pipeline work. They can be mounted in any position provided they are protected from weather.

Where the installation is in an enclosed area, the internal relief vent can be piped outside. A balanced two stage regulator results in accurate regulation and high operational reliability. This regulator series has full Measurement Canada approval (AG-0522) for Pressure Factor Metering.
