Q641F pneumatic stainless steel ball valve

Shanghai crown ring Valve Manufacturing Co., pneumatic stainless steel ball valve, Q641F pneumatic stainless steel ball valve is mainly used for cut off or connected line of medium, it can also be used for fluid regulation and control, and it is compared with other valves, with the following Some advantages. First, the details: Q641F pneumatic valve is mainly used for cut off or connected line of medium, can also be used for fluid regulation and control, and it is compared with other valves, it has the following advantages. Second, the pneumatic valve structure features: 1, fluid resistance is small, is the smallest of all the ball valves in fluid resistance, even reduced diameter valve, the fluid resistance is quite small. 2, stem thrust bearings reduce friction torque, smooth and flexible long-term operation of the valve stem. 3, good seat sealing performance, use seals made of elastic material such as Teflon, structure easy to seal, and the ball valve closure increased capacity with medium pressure increases. 4, valve stem seals and reliable, due to the rotational movement of the stem only for imitation without making movement at the stem packing seal is not easy to destroy, and the sealing ability increased as the pressure medium increases. 5, PTFE and other materials have good self-lubricating, ball and friction loss is small, so the ball's long service life. 6, download type stem and stem head convex order to prevent the exhaust valve stem, stem seal damage such as fire, convex order and the body can be formed metal contact, to ensure that the valve stem seal. 7, anti-static function: a spring between the ball, valve body, static electricity switching process produces exported. Stainless steel ball valve pneumatic actuator Third, using the new series of GT type pneumatic actuator, double acting and single acting (spring return), rack and pinion drive, safe and reliable; large diameter valves adopt series AW pneumatic actuator fork formula transmission, reasonable structure, the output torque, a double-acting and single-acting. 1, gear dual-piston, output torque, small size. 2, the choice of aluminum alloy cylinder material, light weight, beautiful appearance. 3, at the top, bottom installation manual operating mechanism. 4, the rack connector opening angle can be adjusted, the rated flow. 5, the actuator feedback signal indicates the optional charging and various annexes to automate operations. 6, IS05211 standard connection provides easy installation replacement product. 7, both ends of the adjusting screw allows the standard product section at 0 ° and 90 ° adjustable range of ± 4 °. Ensure the accuracy of synchronization with the valve. Fourth, the attachment options: Depending on the requirements of the control and choice of the following accessories: cut off Accessory: single solenoid valves, double solenoid valves, limit switch back to the hearing. Modulating Accessories: Electrical locator, pneumatic positioner, electrical converters. Gas processing Accessories: Air filter regulator, Gas processing FRL. Manual mechanism: HVSD handheld agency V. Standard: 1, the design and manufacture: GB12237-89, API608, API 6D, JPI 7S-48, BS5351, DIN3357. 2, flange dimensions: JB / T74 ~ 90 (JB74 ~ 90), GB9112 ~ 9131, HGJ44 ~ 76, SH3406, ANSI B16.5, JIS B2212 ~ 2214, NF E29-211, DIN2543. 3, the length of the structure: GB12221-89, ANSI B16.10, JIS B2002, NF E29-305, DIN3202. 4. Verify that the primary test: JB / T 9092, API 598. Pneumatic stainless steel ball valve http://www.ghval.com/productlist/qf-1.html http://www.ghval.com/product/qf/121.html Shanghai
