What is the main difference between superposition valve and ordinary valve slide valve?

The main differences are different attributes, functions and characteristics, and different applications, as follows:

First, the nature is different.

1, superposition valve

Superposition valve is a kind of hydraulic valve, which is divided into direction control valve, pressure control valve and flow control valve. But the superposition valve does not have the function of reversing valve.

2. Hydraulic valve

Hydraulic valve is a kind of automation components operated by pressure oil.

3. Slide valve

Slide valve is a kind of diverter valve, which uses the spool (plunger and disc) to slide on the sealing surface to change the position of the fluid inlet and outlet channels to control the fluid flow direction.

Second, the functions and characteristics are different.

1, superposition valve

Compared with the traditional hydraulic valve, the biggest feature of the superposition valve is that it can achieve the purpose of system installation without using pipelines, thus reducing the leakage, vibration and noise of the system. Compared with the traditional pipeline connection, the superposition valve does not need special installation skills, and it is very convenient to change the function of the hydraulic system.

2. Hydraulic valve

The hydraulic valve is controlled by the pressure oil of the pressure distribution valve, which is usually used in conjunction with the electromagnetic pressure distribution valve, and can be used to remotely control the on-off of the oil, gas and water pipeline system of the hydropower station.

3. Slide valve

It is often used in steam engines, hydraulic and pneumatic devices, etc. So that the motion mechanism can move in a predetermined direction and stroke or realize automatic continuous operation.

Third, the application is different.

1, superposition valve

Suitable for various industrial hydraulic systems, such as injection molding machine hydraulic system, numerical control machine hydraulic system, metallurgical equipment hydraulic system, etc.

2. Hydraulic valve

Hydraulic transmission is used to control the pressure, flow and direction of liquid, and is often used in oil circuits such as clamping, control and lubrication.
