Safety Selector Valves:

Features: The Anderson, Greenwood Safety Selector Valve (SSV) is a unique device, developed to provide a safe and efficient method of switching from an active PRV to a standby PRV. The SSV has less than 3% pressure drop to the active PRV inlet, in accordance with ASME Section VIII Code and API RP520 Part II. The SSV is provided with a 'foolproof' locking mechanism. Tandem Safety Selector Valve systems are available which allow positive and simultaneous switching of both inlet and outlet SSV's while maintaining overpressure protection at all times.
