The Closed Spring Loaded Low Lift Type Safety Valve manufactured by GMK is often used in machines and pipes that convey fluids The valve detects the pressure in the system at its intake in order to carry out its job. The disc of the valve will open when the intake pressure reaches the required level, and it will close when the pressure drops below that level. These devices have the main purpose of putting an end to flames and explosions that occur inside pressure vessels and heat exchangers. In order to prevent a dangerous buildup of pressure or fluid and subsequent release, it is equipped with automated release mechanisms that operate according to predetermined set points.
In a Closed Spring Loaded Low Lift Type Safety Valve, the disc rotates just a quarter of an inch of the bore diameter. Because the disc only moves up a little distance, their capacities of themselves are often quite a bit smaller than those of full or high-lift valves, and the discharge area is wholly determined by the disc’s position. In the event that there is an overpressure condition, a Closed Spring Loaded Low Lift Type Safety Valve will be fitted so that the pressurized system or vessel will not sustain any harm.
Benefits
In steam systems, GMK Closed Spring Loaded Low Lift Type Safety Valve is often used for the purpose of providing protection against boiler overpressure in addition to serving other purposes, such as being installed downstream of pressure lowering devices.
Although its principal function is to provide safety, it is also used in the processing industry to protect products from being harmed as a result of excessive pressure.
