Liquid Relief Valves 

Model Descriptions:
Model 71S: Cast iron body with SS seat and disc. Pressure-tight hood.
Model 171: Carbon Steel (CS) with SS seat and disc. Pressure-tight hood.
Model 171P: Same as model 171 with packed lift lever.
Model 171S: All 316 SS construction including spring. Available with pressure-tight hood or packed lift lever.

Features & Benefits:

  • Suitable for back pressure to 50 psig. (Back pressure increases set pressure on a one to one basis, and reduces capacity. Back pressure in excess of 10% of set pressure is not recommended.)
  • Seats lapped for optimum performance.
  • Ball pivot between disc and spring corrects misalignment and compensates for spring side thrust.
  • Stainless Steel (SS) springs.
  • Each Kunkle valve is tested and inspected for pressure setting and leakage.
