POPRV – Series 700

SERIES 700 POP ACTION SAFETY VALVE

The Series 700 is an all metal seated pop action pilot and main valve that extends the use of pilot technology to temperatures up to 1,000°F (538°C). It is suitable for steam and/or gas service applications at pressures to 1,200 psig (82.8 barg).

GENERAL APPLICATION

The Series 700 is suitable for steam and/or gas service applications at temperatures up to 1000°F (538°C) and pressures to 1200 psig (82.8 barg).

FEATURES

  • All metal-to-metal seating surfaces for high temperature service and enhanced chemical compatibility.
  • Patented flexible disc reduces impact wear while increasing seat tightness.
  • Dampening chambers control opening and closing response, increasing valve cycle life.
  • Non-flowing pilot reduces seat wear and minimizes entrance of dirt and particulates.
  • Remote sense option available at no added cost.
  • Easily adjustable blowdown between 3% and 15% eliminates the need for upper and lower blowdown rings and pins, saving time, parts and costs.
  • ASME Section VIII and Section XIII (UV Designator) Code Stamp for steam and gas services.
  • Unique field test capability allows accurate set pressure verification with valve in service with no system isolation block valve or rupture disc required.
  • Patented manifolded dual pilots option for maximum operating reliability.
