Pressure Relief Valve - Spring Loaded The ‘IT’ spring loaded pressure relief valves are suitable for surge relief pressures not exceeding 25bar. When the system pressure reaches the relief set point, the valve opens to reduce the system pressure.
Adjusting the Relief Set-Point The pressure relief set-point is adjustable by adding or removing spring washers. Adding spring washers increases the pressure relief set-point and vice versa.
Lubrication The ‘IT’ pressure relief valve is equipped with grease nipples to lubricate the sealing surfaces on the valve’s shuttle, thus preventing corrosion and scale buildup on the sealing surfaces.

10 bar (147 psi) - 250 bar (3675 psi)
Flanges - SABS 1123, BS4504, BS10, ASME B16.34
Couplings - Tapered shoulders type and other pipe coupling types.
Pressure Relief Valve - Nitrogen Charged The ‘IT’ nitrogen charged pressure relief valves are suitable for surge relief pressures exceeding 25 bar. When the system pressure reaches the relief set point, the valve opens to reduce the system pressure.
Adjusting the Relief Set-Point The pressure relief set-point is adjustable by increasing or decreasing the nitrogen pressure in the control compartment Increasing the nitrogen pressure increases the pressure relief set-point and vice versa.
Compatibility with Isolating Valve The ‘IT’ nitrogen charged pressure relief valves are fully compatible with the ‘IT’ isolating valves and can be converted with minimal cost and time.
