MODELS 19/19M/20/20M/20P/20MP/200A/200H LIQUID RELIEF VALVES
• Inlet and outlet connections cast integral with body for easy inspection and servicing without disconnecting piping.
• Available with optional female NPT inlet or flanged inlet and outlet connections.
• Beveled seats lapped for optimum performance.
• Stainless steel spring for optimum corrosion resistance.
• Spherical pivot between disc and spring corrects misalignment and compensates for spring side thrust.
• Tested and inspected for pressure setting and leakage.
GENERAL APPLICATION
A range of valves suitable for overpressure relief and protection of pumps, tanks, lines and hydraulic systems; pressure regulation and continuous by-pass relief.
