Apa itu Katup Kontrol Pneumatik/Katup Pengatur Pneumatik?
COVNA Pneumatic Control Valve includes ZJHP series and ZJHM series. ZJHP/ZJHM series mini pneumatic diaphragm regulaton valves,developed by our company using the advanced technology inside and outside China according to the IEC standard,are a new generation actuators. The product comprises a multiple spring zero adjustable actuator, a low flow resistance sleeve and a single seat regulation valve without lower cover. Its size and weight reduce by 1/3 respectively, and the flow capacity increases by 1/3. It's of low center of gravity, high vibration  resistance and easy for installation.The performance indexes are superior to products of the same kind,corresponding to the foreign CV3000 serials regulation valves. The products are widely used in automatic production control system in industrials including chemistry,petroleum,light industry, power station, metallurgy.
The Pneumatic Control Valve is to use compressed gas as the power source, the cylinder as the actuator, and with the help of valve positioner, converter, solenoid valve, retaining valve, gas tank, gas filter and other accessories to drive the valve, realize the switch value or proportional adjustment, receive the control signal of industrial automation control system to complete the regulation of pipeline medium: flow, pressure, temperature, liquid level, etc Various process parameters. The characteristics of pneumatic control valve are simple control, rapid response, and intrinsic safety, no need to take additional explosion-proof measures.
 

Bagaimana cara kerja katup kontrol pneumatik?
By receiving the control signal pressure output by the standard electric signals of the regulator(via electricity-air positioner or electricity-air converter), the valve opening is changed, so as to change the flow of the medium to be regulated and then allow parameters such as flow, pressure, temperature and liquid level to be regulated. As a result, the production process automation is achieved.
After the extraneous pneumatic pressure signal is input into the diaphragm chamber, it will act on the diaphragm to produce thrust. The thrust them compress the spring pack, and move the push rod, which drives the spindle to open(close) of the valve clack until the balance is achieved between the thrust and reaction of the compressed spring pack and the clack is in a stable position of the stroke. It is concluded from the above principle. There is a definite proportional relation between the clack and the input pressure signal.
