Shanghai Rong Titanium Valve Manufacturing Co., Ltd. is} {QGDF pneumatic control valve professional manufacturers. The quality of survival, integrity and development, has a collection of scientific research, design, manufacture, sales and service in one of the high-quality workforce, strong technical force, advanced production technology. Sophisticated processing equipment, sound detection equipment, a sound quality assurance system to ensure product quality and reliability. Pneumatic control valve product description QGDF a pneumatic control valve (the valve plate) around a fixed rotation perpendicular to the path of the valve shaft, which consists of a piston-type double or single acting (spring return) pneumatic actuators and butterfly valves composition, High rotation belongs regulating or shut-off valve type, with electric - gas valve positioner or solenoid valve, air filter regulator, limit switches (valve back to the hearing), the process can be realized on the pipeline fluid medium ratio adjustment and two off control, so as to achieve the flow of the fluid medium, pressure, temperature, level and other parameters of automatic control. Widely used in gas, turbid liquid, concentrated slurry or ash, suspended particles and other media classes. Product Features 1. Pneumatic valve operating torque, is the smallest of all valves in the operation of a moment, open and close rapidly, driven by compressed air through the piston rack gear mechanical transmission stem to rotary output torque to rotate the valve plate 0 ~ 90 °, will be able to quickly complete the opening and closing movements, simple structure, small size, light weight, low flow resistance, flow coefficient, good sealing performance. Adjustment range. Automated control system instrumentation execution units. 2. Using electric - gas valve positioner to electrical and compressed air as power, control system accepts input 0-10mA DC or 4-20mA DC current signal from the air conditioner, be converted into air pressure signal input and output, changing valve plate rotation angle (0-90 ° at any angle), has a better regulation control flow and other parameters. 3. Electromagnetic valve, valve back to the hearing, to AC220V or DC24V power supply voltage and compressed air, to achieve the fluid medium fast two off control. 4. Pneumatic actuator piston-cylinder and crank conversion structure, the output torque, small compact, fully sealed waterproof design high degree of protection. Cylinder block with mirror cylinder, oil-lubricated, low coefficient of friction, corrosion resistance, with superior durability and reliability. All transmission bearings are self-lubricating bearings using oil-free boundary lubrication, ensuring the shaft does not wear.
