Safety
Selector Valve - Dual Pressure Relief Device Systems -
Anderson Greenwood developed the patented, Safety Selector Valve in response to
the growing demand for cost-effective, dual pressure relief valve and/or rupture
disc installations in today’s process industries. The Safety Selector Valve is
designed specifically to function as an effective ‘switchover’ device that
permits routine or emergency servicing of redundant pressure relief devices with
no process interruption, thus providing continuous system overpressure
protection.
