All Geordi Pressure Relief Valves (PRVs) come with the option of being set or not set to crack/relieve at a nominated pressure. All prices quoted in the price list are valid for PRVs utilizing a standard spring. Standard springs and pressure ranges include:

• Light spring, which will work effectively from a range of 25-50Psi / 172-345Kpa / 1.7 – 3.4Bar.
• Medium spring, which will work effectively from a range of 50-100Psi / 345-690Kpa / 3.4 – 6.9Bar.
• Heavy spring, which will work effectively from a range of 100-150Psi / 690-1035Kpa / 6.9-10.3Bar.

    Geordi also has the capability to adapt our range of pressure relief valves to relieve at pressures outside the standard ranges listed above including the capability to relieve a nominated flow rate at a given pressure ie. Very positive relief or small “cracking -> full opening” pressure differential.

    Note: all pressure relief valves required to operate outside the standard ranges and conditions may incur an additional cost and delivery time due to the requirement of specialized parts.

     Being a small PRV with a small seating area, we prefer to keep relief pressure requirement to more than 1 BAR for this valve due to potential for plunger sticking.

    Seat Materials: The standard seating materials vary for each type of Pressure Relief Valve. Different seating materials are available eg. Teflon, Viton, EPDM, Nitrile, Silicone etc but may require some additional cost from the standard configuration.
