Control Valves (English: control valve) is called abroad: control valve, the domestic habits known as: regulating valve. For regulating the industrial automation process control in the field of media flow, pressure, temperature, liquid level and other process parameters. Automation system according to the control signal, automatically adjust the valve opening in order to achieve medium flow, pressure, temperature and level adjustments.

Oxygen valve series
|
|
|
|
|
|
|
|
|
|
In physical and chemical experiments, Oxygen valves often use oxygen, nitrogen, hydrogen, argon, etc. These gases are generally stored in special high-pressure gas cylinders. When using, it is required to reduce the gas pressure to the point experiments by reducing valve. And then it has fine-tuning by other control valve in order to make gas input use system. The most commonly used oxygen valve is oxygen-reducing valve referred to as oxygen meter.

Stopcock and bellows valve series
|
|
|
|
|
|
|
|
|
|
Stopcock, including bonnet, valve body, valve stem, disc, and with bonnet activity valve stem and disc rotation joint. In axial linear motion, stem is installed with fixed seal connections bellows for bonnet. Bellows and stem is also fixed with seal. The valve stem has guide shaft with spiral groove, and the disc of the transmission connection with solid guide pin handle, guide pin is in spiral groove guide axis, which makes the axial linear motion stem drive through the plug handle to rotate disc.

Hydraulic control valve series
|
|
|
|
|
|
|
|
|
|
Hydraulic control valve is controlled by hydraulic pressure. It consists of one main valve and attached catheter, pilot valve, needle valve, ball valve and pressure gauge, etc. According to the purposes, functions and different places, which can be turned into remote float valve, pressure-reducing valve, slow-closure check valve, flow control valves, pressure relief valve, hydraulic electric control valve, pump control valve, etc.

Ball valve series
|
|
|
|
|
|
|
|
|
|
Ball valve with the same motion of 90 ° rotation, the difference is that the plunger is sphere with circular hole or channel through its axis. In the pipe route, ball valve is mainly used to do cut-off, distribution and the change of medium flow direction. It can shut tightly only by taking operation of 90 ° rotation and slight rotational torque. Ball valve is the most suitable for switch, cut-off valve. But with recent development, ball valve has been designed to have the same usage of throttle and flow control valve, such as V type ball valve.
