Optional Factory Preset
Accurate Set Pressure
Wide Range of Cracking Pressures
100% Seat Leakage Tested
Résilient seal design prevents leakage. Sealing efficiency increases with increased pressure up to cracking pressure. Métal to métal seat on low pressure side supports spring load and prevents sticking.
When system pressure overcomes spring force, poppet opens momentarily exposing variable orifice between poppet and body to pass increasing flow with minimum pressure rise without blowdown.
Résilient seal automatically eslablishes line of contact with spherical seat. Seal provides dead tight reseal very close to cracking pressure.
