First, Aerodynamic High Temperature Globe Valve Product Description
Valve heat sink is mainly used to protect the drive device, so the use of more on the control valve, in general, more than 300 ℃ heat sink, 200 ℃ through the bracket cooling, the drive will not have a significant impact. High temperature valve bonnet to add heat sink is to heat, which is no doubt that the temperature limit of the heat sink without the provisions of the standard, generally in the case of more than 560 ℃ heat sink.

And the best effect of the heat sink is welded with the valve cover, welding can also be, but the effect is not good casting. Pneumatic shut-off valve is simple in structure, easy to manufacture and maintain. The working stroke is small and the opening and closing time is short. The closing body (valve flap) and the sealing surface of the valve seat are tapered, the closing force is small, the erosion resistance and the sealing are reliable. Pneumatic shut-off valve seat can be replaced valve seat, can be any combination with the closure of the sealing surface material matching to meet the working conditions, to extend the service life.

 

Second, Aerodynamic High Temperature Globe Valve Pneumatic Actuator Configuration Features
 1, Compact dual piston gear rack structure, ratcheting precise, smooth transmission output torque stability. 
 2, The cylinder for the extrusion of aluminum alloy, and by the hard anodized, the surface texture of hard, strong wear resistance. 
 3, The same specifications are double acting and single acting (spring reset). 
 4, The piston and the output shaft of the active parts are installed wear-resistant material support, to avoid direct contact between the metal parts to reduce friction and wear. 
 5, Installation, connection size according to the international standard ISO5211.DIN3337 and VDI / VDE3845 design, with the ordinary pneumatic actuator interchangeable. 
 6, The cylinder, the end cap. Output shaft, spring, fasteners, etc. are anti-corrosion treatment. 
 7, The installation of the output shaft connection hole has a variety of shapes (square hole. Flat hole. Shaft hole) to choose from. 
 8, There are room temperature type. High temperature type, low temperature type. 
 9, Single-acting spring pre-compressed after the installation, easy to install, disassemble, and good security. 
 10, Beautiful appearance, light weight. Has a waterproof performance.

 

Third, The Function And Use Of Pneumatic Actuator Accessories
 Dual use as pneumatic Actuator: control valve opening or closing. 
 Single acting Pneumatic Actuator: Circuit. When the air is cut or faulty, the valve is automatically closed. 
 Single solenoid valve: valve when the power supply is turned on or off, when the valve off or open. 
 Double solenoid valve: a valve when the valve is turned on. When the other coil is energized, the valve is closed and the memory function is 
 Recirculated: the remote return valve opens or closes the signal. 
 Electrical positioner: According to the size of the current signal (4-20mA) on the valve to open (that is, the media flow) to adjust the control. 
 Electrical converter: the current signal into air pressure signal, and pneumatic positioning supporting the use of. 
 Pneumatic positioner: According to the pneumatic signal (0.02-0.1Mpa) size to control the valve opening, the adjustment control. 
 Pneumatic triple parts: pressure reducing valve. Filter. Oil mist, the gas source stability, cleaning and moving parts from the lubrication effect. 
 Manual mechanism: When the circuit is shut off or faulty, it is used to operate the valve opening and closing

 

 Fourth, Aerodynamic High Temperature Globe Valve Installation, Commissioning And Maintenance
 1, KGT series of pneumatic actuators can be directly connected with the valve, but also through the bracket and connector installed with the valve connection. 
 2, The installation must ensure that the pneumatic actuator output shaft and the valve shaft coaxial. 
 3, Pipe joints and ducts should be clean inside, no waste. Dust and oil and so on. 
 4, Solenoid valve. Electrical locator, electrical converter, pneumatic positioner. Reversal, etc. should be installed according to the relevant instructions. 
 5, Pneumatic actuators at both ends of the adjustment screw, you can adjust the valve opening angle, adjust the nut must be tightened after adjustment. 
 6, The actuator and the valve should be commissioned at the same time, the valve pressure to the rated pressure, the actuator to the gas source pressure 0.4-0.7Mpa on the two inlet switch inlet, observe the valve open and closed, should be flexible and no pause , And repeated trial and error. 
 7, The installation of the solenoid valve pneumatic actuator, commissioning should first use the manual button operation (solenoid button on the red button) debugging, and then power debugging. 
 8, The air supply should be kept dry. Clean, regularly with the actuator in conjunction with the air filter to discharge. Under normal use should be checked once a month, once a year.

Six, Aerodynamic High Temperature Globe Valve Structural Characteristics
 1, Selection of sophisticated, in line with domestic and foreign standards, reasonable structure, handsome in appearance. 
 2, The valve, the valve seat sealing surface with iron-based alloy surfacing or Stellite (Stellite) cobalt-based hard alloy surfacing, wear, high temperature, corrosion resistance, scratch resistance, long service life The 
 4, Stem and quenched and tempered surface treatment, a good corrosion resistance and scratch resistance. 
 5, Can be used in a variety of piping flange and flange sealing surface type to meet the needs of various projects and user requirements. 
 6, The full range of valve material, packing, gasket can be based on actual conditions or user requirements reasonable matching, can be applied to a variety of pressure, temperature and media conditions. 
 7, Inverted seal with a threaded connection Seal or body welded austenitic stainless steel, sealed and reliable, replace the filler can be carried out in the case of non-stop, convenient and quick, does not affect the system operation.
