Advantages of ZJHM Series Top Guide Sleeve WCB Pneumatic High Temperature Control Valve:

● It is cost-effective and safe to be used,which can help you save cost of the whole system and maintenance.
● It has a simple structure and a big torque, explosion-proof with short actuating times,optimized actuating forces and reliable tight sealing.
● It can perfectly avoid problems of friction, corrosion, and emissions.
● It is of low center of gravity, high vibration resistance and easy to install.
● Simple to control, rapid response, and intrinsic safety, no need to take additional explosion-proof measures.
● Fluid channels in a s- shaped streamline, small pressure drop loss large flow, wide adjustment range, high precision flow.
● Especially suitable for leakage requirements is not high, high temperature

Working Principle Of high temperature Pneumatic control valve

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 a thrust. The thrust then 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 ofthe compressed spring pack and the clack is in a stable position of the stroke.It’s concluded from above principle, There’s a definite proportional relation between the clack and the input pressure signal.
