Safety valves are mechanisms that release gas when the limit temperature or pressure value is provided. The safety valve used to ensure safety in boilers or pressurized tanks is an equipment that prevents damage to the system and equipment.
Safety Valves Features
Safety valve can be used in closed circuit heating systems and solar energy systems. Safety valves, which can be produced in accordance with different connection diameters, operate on the principle of counter pressure. It is both an auxiliary equipment and a safety element, as it automatically releases gas at the specified temperature or pressure. Safety valves are manufactured according to the type of fluid, temperature, pressure, capacity and back pressure. However, body material and accessories are also determined by the properties of the fluid. Safety valves can be produced in three types: full lift, proportional lift (proportional) and normal safety valve.
Safety valves can be produced from steel, stainless steel, bronze, monel, hastelloy, duplex and super duplex materials. Safety valves that can be manufactured with flanged or threaded connection feature have a nominal diameter between DN 15 and DN 200. Nominal pressure is between PN 16 – PN 40. Safety valves can be produced for working between (-200 ° C) and (+550 ° C).
Safety valves are widely used in gas compression stations, petrochemical industry, natural gas and oil lines, storage tanks and paper industry.
