Haiqiao Yap Valve Manufacturing Co., Ltd. [BQ641PPL / H] pneumatic valve insulation manufacturer, with large spot to ex-factory sales! Companies adhere to the "quality first, integrity management" purposes, to provide customers with affordable products and perfect after-sales service, welcome to buy! A pneumatic valve insulation Product Overview consistent BQ641PPL / H pneumatic valve has good thermal insulation cold properties, and jacket insulation pneumatic ball diameter and diameter, while effectively reducing the pipeline medium heat loss. BQ641PPL / H insulation pneumatic valve mainly used in petroleum, chemical, metallurgy, pharmaceutical, food and other types of systems to transport will be solidified at room temperature, high viscosity media. As a result of the overall structure, thus holding the ball valve pneumatic valve is smaller than the average size, lighter weight, and no leakage, good sealing performance, jacket securely using more pressure than welded carbon steel casting. Second, the main technical parameters of pneumatic valve insulation nominal diameter DN (mm) 15 20 25 32 40 50 65 80 100 125 150 200 Rated flow coefficient KV 21 38 72 112 170 273 384 512 940 1452 2222 3589 Nominal pressure (MPa) PN1. 6,2.5,4.0,6.4 MPa; ANSI 150,300LB flanged body form: Split casting ball; Wafer: integral cast body flange connection form, clip-on spool form of 'O' type poppet leak rate Q by GB / T4213-92, less than the rated KV0.01% (soft seal: zero leakage) with positioner basic error: less than ± 2% of full stroke hysteresis band locator: less than a full stroke of ± 2% adjustable range of 250: 1 350: 1 configuration actuator GT, AT, ST, AW series of single and double acting pneumatic actuator control mode switch two controls, 4 ~ 20mA analog signal control three pneumatic valve actuator technology insulation Parameters Actuator Model GT, AT, ST, AW series of single and double acting pneumatic actuator supply pressure 0.4 ~ 0.7MPa Air Connection G1 / 4 ', G1 / 8', G3 / 8 ', G1 / 2' Ambient temperature - 30 ~ + 70 ℃ action in the form of single-acting actuators, double acting actuators can be equipped with accessories positioners, solenoid valves, air filter pressure reducer, to secure his position valves, limit switch, valve position transmitter, handwheel institutions using the new aerodynamic actuators, double acting and single acting (spring return), rack and pinion, safe and reliable; large diameter valves using AW series pneumatic actuator fork-type transmission, reasonable structure, output power, 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 mounting manual operating mechanism. 4, the rack can be adjusted opening angle connector, the rated flow. 5, the actuator feedback signal indicative and optional accessories charged to automate operations. 6, IS05211 standard provides a convenient connection to install the replacement product. 7, both ends of the adjusting screw allows the sections of standard products in the 0 ° and 90 ° with the adjustable range of ± 4 °. Ensure the pneumatic valve with internal thread synchronization accuracy.
