CV3000 regulating pneumatic valve performance characteristics < / div >

CV3000 regulating pneumatic valve is fine small pneumatic valve, it is the regulation of our country imported from Japan in the mid - 1980 - s varieties of pneumatic valve, it is only in terms of structure change the single spring type pneumatic diaphragm actuator to more spring loaded diaphragm actuator, pneumatic valve's structure is improved, and not to change. Its most outstanding characteristic is to adjust the weight of the pneumatic valve has fallen by 30%, height decreased by 30%, the discharge coefficient increased by 30%. After that, the domestic fine small adjustment has own design pneumatic valve products. It is the original old products is a kind of improved, so has become the mainstream in the late 20th century. The pneumatic valve body structure have single-seat, two-seater, sleeve, Angle type, tee, high-voltage cage, a variety of forms such as bellows seal, with different pneumatic, electric actuators, which can realize the various kinds of industrial process parameters such as pressure, temperature, liquid level, flow of precise control. It compared with the traditional control pneumatic valve, has the following advantages:
1, the CV value achieved more and more widely adjustable than sex from unique fluid analysis of pneumatic valve body, s-shaped structure can inhibit due to complex flow shape vortex and caused by flow suddenly expanded complex irregular phenomenon such as flow, resulting in efficient medium flow, in addition, the cage of the pneumatic valve fin will be generated around the sleeve of the unstable flow efficiently into the sleeve, due to these characteristics, make CV3000 series regulating pneumatic valve and the original V series pneumatic valve compared with CV value increased by 30%, and adjustable than from spake to expand to 50:1 ( Add attachments can reach 75:1) , thus it can be used in a wider range under the control of load change. Make process gain stable; Computer simulation of the pneumatic valve opening under the condition of process control, can realize flexible control.
3, small size weight light-duty CV3000 series pneumatic valve adjustment due to the simple mechanical structure of spring type small large output force of diaphragm actuator, which successfully reduce the height, to realize miniaturization, according to many spring film pneumatic valve actuators and s-shaped structure, CV3000 type pneumatic valve adjustment can achieve 30% compared with the original old regulating pneumatic valve - The light-duty miniaturization, 40% ( The change of the structure, make it an older regulating pneumatic valve to reduce the weight of 30%) Made a contribution, the effective use of space.
4, specifications complete, widely used CV3000 series regulating pneumatic valve with pneumatic valve from the vacuum to high pressure pneumatic valve, varied from low to high temperature control. Widely used in petroleum refining, petrochemical, chemical fertilizer, general chemical, steel, metallurgy, paper making, power, light industry and other automatic control process.
5, high precision improved CV3000 regulating pneumatic valve, not only has the structure of the pneumatic, also can equipped with small electric actuators, which greatly improve the control precision, and can according to need, need explosion-proof in chemical, petrochemical and other occasions, provide explosion proof electric actuator, broaden the scope of its use and conditions of use. So, CV3000 has not just at the beginning of a pneumatic valve regulating varieties, but developed into a regulating pneumatic valve series, it basically covers straight stroke regulating pneumatic valve of all varieties, choose different material, equipped with different actuators, can be applied to all kinds of pressure, temperature, flow rate, corrosive medium, the places are widely used in various kinds of automation control system.
above, by providing our professional products cover electric/pneumatic regulating pneumatic valve series, self regulating pneumatic valve series, type 0 / V regulating pneumatic ball valve series, regulating butterfly series of pneumatic valve and pneumatic valve American standard series varieties, in strict accordance with the UNI/ASME/ASTM/BS/DIN/API/GB standard ten production manufacturing, size from 1/8 'to 56' ( DN3 - DN1400) , the pressure from CLASS150 to CLASS2500 ( PN16- PN420) And can provide carbon steel, alloy steel, stainless steel, super duplex stainless steel and special alloy materials, such as MONEL products use from temperature 196 ℃ to 650 ℃.
