  • Technical Feature

    OPERATION:

    Flow is blocked from ① to ② until pressure increases to meet the selected valve setting, lifting the poppet from its seat and allowing relief flow through ② to tank. Pressure at ② is additive to the relief setting of the valve. The unique poppet design provides enhanced stability at all flows and pressures.
