Working Principle of PRESSURE CARTRIDGE CONTROL/BALANCE/RELIEF VALVES

Working Principle of PRESSURE CARTRIDGE CONTROL/BALANCE/RELIEF VALVES

In the industrial production process, valves are key equipment for fluid control, and their performance directly affects the stability and safety of the system. This article mainly introduces PRESSURE CARTRIDGE CONTROL/BALANCE/RELIEF VALVES and introduces the details of the working principles of these valves.

1. PRESSURE CARTRIDGE CONTROL VALVE (control valve)
The control valve, as a key component of fluid regulation, receives signals from the control unit and uses the actuator to drive the movement of the valve core to change the valve opening and achieve precise control of fluid flow, pressure and other parameters. The core of this valve lies in its precise adjustment ability and rapid response ability to ensure that the system can operate stably under various working conditions. Its working principle is as follows.
The control valve receives signals from the control unit, which may come from sensors, PLCs or other control systems. According to the received signal, the actuator (such as pneumatic, electric or hydraulic device) starts to move, driving the valve core to move in the valve body. The movement of the valve core changes the valve opening, and then adjusts the flow rate, pressure and other parameters of the fluid.
2. PRESSURE CARTRIDGE BALANCE VALVE (balance valve)
The balance valve is mainly used to maintain the pressure balance in the system and ensure the uniform distribution of the fluid in the system. It adjusts the aperture size or valve core position in the valve to keep the pressure difference when the fluid passes through the valve within the set range. Its working principle is as follows.
The balance valve detects the pressure difference between the inlet and outlet. When the pressure difference exceeds the set value, the valve core automatically adjusts its aperture size under the action of the regulator to return the pressure difference to the set range. Then, through the adjustment of the valve core, the balance valve ensures the pressure balance in the system and the uniform distribution of the fluid.
3. PRESSURE CARTRIDGE RELIEF VALVE (pressure reducing valve)
The pressure reducing valve is a safety device used to automatically release pressure when the internal pressure of the system exceeds the preset value to prevent system damage or accidents. Its working principle is as follows.
The pressure reducing valve continuously monitors the pressure inside the system. When the pressure inside the system exceeds the set value, the valve flap of the pressure reducing valve automatically opens under the action of the spring or other force to release excess fluid or gas. By opening and closing the valve flap, the pressure reducing valve adjusts the internal pressure of the system to a safe range.
