SERIES 8200/8300 SAFETY RELIEF VALVES
Taylor Valve 8200/8300 Safety Relief Valves are engineered and manufactured to the
highest standards and feature a “state-of-the-art” soft seat which gives you a bubble-tight seal
for hundreds of “pops”. Our unique patented radius disc design assures a reliable reseat even
under the most difficult conditions.
USES: Air, Gas, or Liquid relief applications, including compressors, separators, heater treaters,
free water knockouts, scrubbers, dehydrators, thermal relief, gas production units, transmission and
gathering lines, chemical plants, refineries, meter runs, gas plants, and other industrial applications.
FEATURES
• ASME Section VIII Div 1 code rated for Air,
Liquid and Gas
• Zero Leakage to set point
• Extremely Adjustable
• Superior Spring Design and Material enhance
the performance of the product and provide
consistent opening and closing pressures.
BENEFITS
• Our Patented Radius Disc reduces the amount
of interference required to seal and assures a
reliable reseat even under the most difficult
conditions - up to hundreds of “pops”.
• High Endurance Soft Seat supports repeated
operation and a bubble-tight shutoff everytime
• Radius Disc and Seat Design supports the
spring alignment and promotes proper seating
• Low Simmer Rate
• Consistent Blowdown
GENERAL OPERATION
Taylor’s 8200/8300 Series Safety Relief Valve
actuates when the pressure under the valve
overcomes the spring force on the disc causing
the valve to open, releasing overpressure from the
system before re-closing.
