SAFETY
SELECTOR VALVE
Features: The Anderson, Greenwod 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 withich allow positive and simultaneous
switching of both inlet and outlet SSV's while maintaining overpressure protection
at all times.
