Connection mode of hydraulic valve of hydraulic press

Threaded connection

Hydraulic valves with threaded ports are called pipe valves. Connect the oil hole of the pipe valve to the pipe with a threaded pipe fitting, then secure it to the pipe. This type of connection is suitable for simple hydraulic systems with small flow rates. Its advantages are: simple connection, convenient layout, at a glance, the oil channel between the valves in the system is clearly visible. The disadvantage is that the components are scattered and take up a lot of space. Pipeline overlap, many joints, so inconvenient loading and unloading and maintenance, but also easy to cause oil and air infiltration at the pipe joint, sometimes produce vibration and noise.

Flange connection

It is connected to the flange at the end of the pipe through the wire hole on the valve body and is connected together with screws. The valve is called a flanged valve and is suitable for large flow hydraulic systems with a diameter of 32mm or more.

Flat plate connection

The oil holes of the hydraulic valve are arranged on the same mounting surface and are provided with connecting screw holes. The valve is called a plate valve. Screw the flat valve onto the connector with the appropriate port of the valve. The advantages of this type of connection are that it is easy to change components, it does not affect the pipe, and the gate valve can be centered. Connections to plate valves are available in three ways: connection plates, oil plates and integrated blocks.
