SAFETY VALVE FLAMCO 1 1/4x2,5 bar FT BRASS

Product code
3941336
Prescor safety valves for closed heating and cooling systems. Prescor safety valves have a special design that ensures perfect sealing and high venting capacity. The valve uses high-quality rubber that withstands temperatures up to 140 °C and meets the hardness requirements set by the valve's opening pressure, preventing the valve from sticking to its seat. All valves undergo a verification procedure before leaving the production line. Safety valves can be used to protect heating and cooling systems. They are suitable for use in systems containing up to 50% glycol solution. Features
  • Minimum/maximum operating temperature: -10 °C / 120 °C
  • Instantaneous maximum temperature: 140 °C
  • Compatible with up to 50% glycol solutions
  • CE marked (PED 2014/68/EU), for use in applications compliant with the pressure equipment directive
  • Tolerance for set pressure: -5 % / +5 % (for NF certified valves, tolerance is -0 % / +10 %)
