DJ41Y low temperature cut-off valve details: First, the product features: low temperature cut-off valve usually refers to the working temperature is below -46 ℃ valves are widely used in liquefied natural gas, liquefied petroleum gas and other cryogenic industries. Valve Manufacturing currently applicable temperature of -196 ℃ shutoff valve shut-off valve, all parts are made of liquid nitrogen cold pretreatment, completely avoid the use of the process of sealing leaks deformation. Price low cut-off valve switch plunger valve plunger seals in the slow-moving low temperature cut-off valve supplier, the contact surface hardly worn off, the plunger is inserted under seal, cut off the flow channel; when you turn the valve Shandong column Although the plug from under the ring, but still hidden in the inner ring, keep the outside world, will not leak. Because the surface of the plunger through high-precision cylindrical grinding machine processing. Sealing ring using elasticity, high wear resistance, non-toxic new sealing material, so a reliable seal and durable. Thereby increasing the life of the valve plunger.
