DJ41Y low temperature cut-off valve with a special low temperature steel valves, the rough parts inside the cooling medium for several hours (2-6 hours) to relieve stress, to ensure that low-temperature properties of materials, guarantee finishing size stainless steel valves, in order to anti-valve conditions at low temperature, due to temperature changes caused by deformation caused leaks. The valve assembly is different from ordinary valves, parts subject to rigorous cleaning, remove any oil, in order to ensure performance. DJ41Y low temperature cut-off valve details: I. Features: low temperature cut-off valve usually refers to temperature below -46 ℃ valve, widely used in liquefied natural gas, liquefied petroleum gas and other low-temperature industries. Valve currently applicable temperature of -196 ℃ manufacture of valves, all parts are made of liquid nitrogen cryogenic pretreatment process to avoid completely deformed seal leakage. DJ41Y low temperature cut-off valve in the valve between the plunger and the sealing ring with an interference fit, by adjusting the gland flange bolts, the seal ring compression generated by the lateral force in the valve body bore surface and cylindrical plunger seal, thus ensuring the tightness of valves to eliminate the internal and external leakage while the valve opening torque is small, can achieve rapid valve opening and closing. Valve Co., Ltd. Shandong Everbright produce such a wide range of application types of valves, valve quality and reliable brand, no leakage, leakage phenomenon, frequent switching is not stuck, rusted, the majority of chemical plants, thermal power plants, steel mills, printing and dyeing plants, food plants the best choice.
