Standby Systems Inc. is a distributor for Bryan Donkin RMG of Canada. Since 1803, Bryan Donkin has been manufacturing pressure regulators, associated safety devices and related equipment for the gas distribution industry. The product line includes service regulators and components, some shown below, and system regulators including customized regulating stations. These regulators and relief valves are also recommended for propane vapor and manufactured gases. The product line is largely interchangeable to Fisher, Actaris, etc. and priced very competitively. Contact us for application information and pricing.
Series 290 & 309 Slam Shut Valve Assembly
The series 290 & 309 Slam Shut Valve Assemblies are specifically designed to protect downstream equipment from either under or over pressure conditions. The series 290 is an over pressure protection model. The series 309 is available in over pressure protection or under/over pressure protection models. 309LP2 and 309LP4 versions are suited for higher inlet pressures and are ideal for propane vaporizer discharge applications. The safety slam shut valve will remain closed until it is manually reset. No tools are required to reset the valve.
