Electric high-pressure regulating valve is a pressure-balanced valve, [electronic] by the electric actuator and high voltage cage type regulating valve body. Body fluid channel S streamlined, the pressure drop, flow rate, adjustable wide range suitable for the requirements of dynamic stability, low noise, small cavitation corrosion of high pressure drop applications. Second, the electric high voltage cage type regulating valve body type: straight single-seat casting ball valve nominal diameter :40,50,80,100,150,200,250,300mm nominal :ANSI 900,1500,2500 JIS 63K Note : DN250 ~ 300 non-ANSI 2500 Connection Type: flange sealing surface type RF, RJ flange standard :JIS B2201-1984, ANSI B16.5-1981 welded connection: welding scarfing SW [40 ~ 80mm butt welding BW [80] ~ 300mm] Material: Body, the trim material combinations and operating temperature range · seat to allow the leakage bonnet: room type P -5 ~ + 230 ℃; elongation I type EI + 230 ~ + 566 ℃; Note : Working temperature must not exceed the allowable range of various materials. Gland type: Bolt Clamp Packing: asbestos braided packing, graphite packing electric shut-off valve advantages of a simple structure butterfly manufacturers, manufacturing and maintenance more convenient. 2, the working stroke is small butterfly parameters, short opening and closing time. 3, sealing butterfly valve, sealing surface between the friction force is small, longer life expectancy. 4, in the form of bellows globe valve body structure has a straight-through DC and right angle. Straight-through is the most common configuration, but resistance to its maximum fluid. DC-type fluid resistance is small, used for containing solid particles or viscosity of the fluid. Right Angle butterfly valve forging how much more, for smaller circulation, high pressure shut-off valve. 5, the opening and closing process than the valve sealing surface friction, wear. 6, usually only one sealing surface, the manufacturing process, and easy maintenance. 7, the electric actuator for easy operation. Butterfly _ Tianchang instrument parameters associated instruments (certification) _ valve provided by the United Instrument Sales Co., Ltd. Tianchang instrument. Instrument Sales Co., Ltd. Tianchang instrument Union (www.ylybxs.com) (www.ylybxs.com) is Chuzhou, temperature instrumentation leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs.
