Differential pressure control valve working principle：

The differential pressure control valve does not need any external energy. It can automatically adjust by relying on the pressure change of the regulated medium itself, automatically eliminate the flow change caused by the residual pressure head and pressure fluctuation of the pipe net...

Classification of Control Valves

Balanced trim control valves are usually divided into static balance valves, dynamic flow balance valves and dynamic differential pressure balance valves.

A. Stat...

The automatic flow valve is a kind of valve that controls the flow rate of the throttle by changing the hydraulic resistance of the throttle under a certain pressure difference so as to regulate the movement speed of the actuator (hydraulic cylinder or hydraulic motor). It mainly includes throttle valve, speed regulating valve, overflow throttle valve a...

Double Regulating Valve Working Principle

Balance valve is a dynamic and static balancing valve under hydraulic conditions. Such as static balance valve, dynamic balance valve.Valve body material: cast iron, cast steel,Work pressure is 0.6-4.0 MPA.The working temperature is - 5 C - 350 C.Valve caliber DN15-DN300,Connection mode: flange, internal thread,Driving mode: manu...

Balancing Valve Types

1.Static Balance Valve: It is also called Balance Valve, Manual Balance Valve, Digital Lock Balance Valve, Double Position Regulating Valve, etc. It changes the flow resistance through the valve by changing the clearance (opening) between the spool and the seat to achieve the purpose of regulating the flow rate. Its object of action is the resistance of the sys...

As one of the primary regulation methods of hot water heating system, the return water temperature regulation method of hot water heating system is suitable for the pipeline network without regulating valves. When the balance valve is not installed at the user's entrance of the pipe network, or when the pressure gauges at both ends of the ordinary control valve are not complete at the entrance, or even when the pipe network entrance only has the ordinary valve, the return water temperature re...

The difference between the two balancing valves is that the thermostatic balancing valve

manually adjusts the opening degree of the thermostat valve, while the auto balancing valve automatically adjusts the opening degree of the thermostat valve by using temperature sensors.

Thermostatic balancing valve (referred to as constant temperature valve) is an energy-s...

The radiator thermostatic balancing valve is a self-operated constant temperature flow control valve mounted on the radiator. It is composed of a thermostatic valve body and a temperature regulating device for air temperature sensing. The principle of action is that the opening of the thermostatic valve body is automatically controlled to change the amount of hot water passing through the radiator. When the room temperature is lower than the set temperature value, the
