Threaded valve applications and characteristics
Stainless steel gate valve, Z15W gate valve, threaded gate valve, threaded gate role: gate valve can only be fully open and fully closed function, can not be adjusted and throttling Suitable medium: oil, water, steam and other valve applications: chemical, petrochemical, petroleum, papermaking, mining, electricity, liquefied petroleum gas, food, pharmaceuticals, water supply and drainage, municipal services, machinery and equipment support, electronics industry, urban construction and other fields. Gate valve features: (1) small flow resistance. The valve body inside the media channel is straight through, the medium into a straight line flow, flow resistance. (2) Comparison of valve opening and closing more effort: Whether it is open or closed, gate direction of motion are perpendicular to the direction of medium flow. (3) height, opening and closing time long. Gate opening and closing stroke larger, drop is carried out by the screw. (4) water hammer phenomenon is not easy to produce. The reason is a long time off. (5) The medium can flow in any direction on both sides, easy to install, and the sides of the channel are symmetrical. (6) The length of the structure (the distance between the two connecting end faces of the shell) is small. (7) Simple shape, short structure length, good manufacturability and wide range of application. (8) Compact structure, good valve rigidity, smooth passage, small flow resistance, stainless steel and hard alloy sealing surface, long service life, PTFE packing, reliable sealing, light and flexible operation. Gate valve installation Notes: (1), hand wheel, handle and transmission are not allowed to lift, and no collision. (2), double gate valve should be mounted vertically (ie stem in a vertical position, the hand wheel at the top). (3) The gate valve with bypass valve should open the bypass valve before opening (to balance the pressure difference between inlet and outlet and reduce the opening force). (4), with the gate valve drive, according to the instructions of the product installation instructions. (5) Lubricate at least once a month if the valve is constantly on and off. Other technical parameters Remarks: (1) gate valve price by the caliber, material, pressure varies. (2) Type of connection: thread, flange, welding, etc. (3) Transmission: manual, gear transmission, pneumatic, electric, etc. (4) Diameter from DN6-DN10; pressure from 1.0MPA-64MPA; temperature -20--300 ℃ (5) Material: carbon steel, stainless steel, alloy steel, chrome molybdenum steel, low temperature steel, ductile iron and other special 2 Stage Gear Pump,Priority Gear Pumps,Compactor Gear Pump,Priority Pump GRH , https://www.grhcn.net
