Reliance Low Pressure, Tempreture, Vacuum Relief Valve 20mm (3/4") - LTV575

RMC’s Pressure and Temperature & Vacuum Relief (P, T & V Relief) Valves are safety controls which ensure that the temperature of the water in a pressurised unvented water heater cannot exceed 99° C in the event that the normal thermostatic controls fail. P, T & V Relief Valves incorporate a vacuum breaking (air-inlet) device to protect the cylinder against implosion during the contraction cycle in lower working pressure hot water cylinders. These valves may be used to guard against overtemperature and over-pressure hazards wherever water is stored in unvented containers, particularly in lower working pressure hot water systems. This is a requirement of Australian Standard AS 3500-4. RMC P, T & V Relief Valves are available in 15 mm and 20 mm confi gurations. 

  • Lower operating pressure range
    Ideally suited for lower working pressure hot water cylinders
  • Integral vacuum breaker device
    Offers protection against implosion during contraction cycle
  • Auxiliary pressure relief device
    Prevents pressure building up in the event of a blockage in the drain line
  • Female BSP thread on outlet thread
    Prevents incorrect installation to the tank
  • Plastic coated temperature probe
    Prevents electrolysis of the probe outer casing
  • Dezincification resistant
    Meets Australian Standard for potable water supply
  • Sealed spring cavity
    Prevents spring from seizing in the event of calcification
  • Suitable for horizontal or vertical installation
    Valve designed to work effectively in either orientation
  • Individually tested and calibrated
    Every valve is tested to ensure higher quality and performance

The Pressure, Temperature and Vacuum Relief (P, T & V Relief) Valves should be installed at the heater. System inlet pressure should be no higher than 80% of the set pressure of the P, T & V Relief Valve.
