Fisher™ H200 Series Relief Valves

Fisher

H200 Series pop relief valves are direct-operated relief valves with preset and pinned spring retainers. When the inlet gas pressure increases above the spring setting, the poppet and disk assembly is pushed away from the orifice. With this simple operation and wide spring setting selection, the H200 Series Pop relief valves may be used where venting to atmosphere is acceptable and where some pressure relieving tolerance is acceptable. A common application is on farm tap installations.
