Precision flow control valve

Precision flow control valve body adopts full channel, straight flow and streamline design, and adopts diaphragm type or piston type structure. The outlet pressure is set by using the pressure regulating guide valve spring pressure and adjusting needle valve opening, and the outlet pressure can be stabilized through the feedback of the control system and control room.

solenoid valves manufacturers

Solenoid valve is an industrial equipment controlled by electromagnetic control. It is an automatic basic component used to control the fluid. It belongs to the actuator and is not limited to hydraulic and pneumatic. Adjust the direction, flow, speed and other parameters of the medium in an industrial control system. The solenoid valve can cooperate with different circuits to achieve the expected control, and the control precision and flexibility can be guaranteed. There are many kinds of solenoid valves. Different solenoid valves play a role in different positions in the control system. The most common ones are one-way valve, safety valve, directional control valve, speed regulating valve and so on. We have the best solenoid valves manufacturers.

24v solenoid valve

Why is the connection between the 24v solenoid valve
A diode in parallel is just a light-emitting diode, which has no other effect than the role of luminescence. If the power of the power supply is reversed, it will not emit light and will not function as the indicator light. It doesn't affect the device.
A parallel diode is a continuation diode which ACTS as an antielectric potential of the discharge coil. When the coil is charged, the diode ends with a reverse voltage. If the power supply polarity is reversed, the power will be short and damaged. The polarity of the coil must not be reversed.

Gas burner principle

When the combustible gas (city gas, natural gas, liquefied petroleum gas) is controlled by the microcomputer control system into the combustion head of the burner according to the program, the primary air is mixed with the combustible gas, ignited and burned, and the secondary air helps the combustion to achieve full combustion. The combustion status is detected and controlled by the flame automatic tracking system. When the combustion is faulty (the combustion chamber is oxygen deficient, the combustible gas is under pressure, the combustible gas is interrupted, the gas volume is insufficient, etc.), the control system issues a command that the solenoid valve of the gas supply system is rapidly closed , Cut off the gas supply, the burner automatically shut down after the purge, indicating failure.
