About Leser Safety & Pressure Relief Valves
A safety relief valve in the 4373 series opens automatically once line or vessel pressure reaches a set point, discharging fluid to relieve overpressure and reseating once pressure drops back to a safe level — the set pressure, orifice size (API letter designation) and body material together determine the valve's actual protective capacity, and none of these can be assumed from the model prefix alone. Leser's range covers conventional, bellows-balanced and pilot-operated designs for gas, steam and liquid service, in materials from carbon steel to stainless for corrosive or high-temperature process fluids. Because a relief valve is a certified safety device, the set pressure is fixed at the point of supply or by an accredited test bench, not adjusted freely on site.
Leser Safety & Pressure Relief Valves in Saudi Arabia
Safety relief valves of this type are mandated wherever a pressure vessel, boiler or process line falls under pressure-equipment code, which covers most of Saudi petrochemical and refining plant in Jubail and Yanbu, gas processing facilities, and steam boilers in desalination and district-cooling plants. Set pressure and orifice size must match the vessel's design pressure exactly as recorded on its inspection certificate, so replacement or re-certification of a relief valve normally goes through the plant's pressure-safety or inspection department rather than being sourced generically. High-sulphur and high-H2S process streams common in Saudi gas processing call for material and trim selection matched to the service fluid.
Ordering and lead time
Quote the full valve model and set pressure together, for example 4373.2604 with the set pressure in bar as recorded on the vessel's data sheet or the valve's original certificate — orifice size, connection rating and body material must all be confirmed against the protected equipment, not assumed from the model number alone. Razz sources these valves to order with delivery duty-paid into Saudi Arabia; standard lead time is 3 weeks from confirmed order, longer if a factory test certificate is required. No local stock is held.
Specifications are taken from the supplier's published catalogue data. Confirm against the manufacturer's current datasheet before ordering.
