Quality is everything! US Walker (WORK) imported steel globe valve, also called cut door, is the most widely used as a valve, the reason it's popular is due to the process of opening and closing between the sealing surface friction is small, relatively durable, open height is not easy to manufacture, easy maintenance, not only for low-voltage, and suitable for high pressure. Cut-off valve is to control the use of valve opening and closing of valves, mainly for medium and high caliber of work pressure is not the occasion. The main shut-off valve is open and close the valve and seat components, valve seat along the center line of mobile, changing the distance between the valve and seat, can change the channel cross-sectional area to control and cut off the flow. This type valve in the pipe should generally be installed horizontally. When the internal thread cut-off valve open, the valve opening height for the nominal diameter of 25% to 30%, the flow has reached the maximum, indicating that the valve has reached the fully open position. So closing the valve fully open position, the valve stroke should be determined. Lined globe valve opening and closing parts of the plug-shaped valve, flat or cone, along the centerline of the valve seal the fluid leaving it in a straight line. Stem form of exercise with lifting rod (stem down, the hand wheel does not lift), but also lift rotating rod (hand wheel and stem rotation movements, nut located in the body). Valve has the following advantages: 1. The working stroke is small, open and close a short time. 2. Simple structure, manufacturing and maintenance more convenient. 3. sealing, sealing surface friction force is small, longer life expectancy. Technical parameters Notes: 1, cut-off valve price by a different caliber, materials, pressure varies! 2. Transmission: 3, connection type manual, worm gear, pneumatic, electric, etc.: Wafer, lug type of clip, flanges, welded (butt), etc. 4, material: carbon steel, stainless steel, alloy steel, chrome molybdenum steel, cold steel, ductile iron and other special steel; 5, caliber from DN6-DN1200; pressure from 1.0MPA-32MPA; temperature -100 ℃ -600 ℃ ordering please provide the following information: a nominal diameter (? mm), PN (MPa), and the operating temperature range of 2? straight before the pressure regulating valve, the valve pressure 3? media name and status at 4? single-seat control valve supply voltage (220V or 380V, the default 220V) 5? Input signal: 4-20mA, or 1-5V (default 4-20mA) 6 single-seat control valve body, the trim material requirements of seven other special requirements (such as corrosion resistance requirements, proof grade requirements, leakage class limits?? , etc.) United States Walker (WORK) Valve Chinese agents welcome you to inquire and order!
