Background

The slide valve is a flow dividing valve which utilizes a valve core (plunger piston and valve clack) to slide on a sealing surface and changes the positions of fluid inlet and outlet channels to control the flow direction of fluid. Slide valves are commonly used in steam engines, hydraulic and pneumatic devices, to allow the movement mechanism to achieve a predetermined direction and stroke of motion or to achieve automatic continuous operation. When the slide valve function reversing valve is in the Neutral Position (Neutral Position) or the Normal Position (Normal Position), the communication mode of the oil ports in the valve is called the slide valve function of the reversing valve. The slide valve function directly affects the operating state of the actuator, and different slide valve functions can meet different requirements of the system. It is important that the spool valve function be properly selected.

Slide valves are classified into two types, reciprocating and rotary, according to their structural and operational characteristics. The reciprocating slide valve has 3 kinds of plane type single valve clack, plane type double valve clack and plunger type. Plunger slide valves are widely used in hydraulic and pneumatic devices. The valve clack of the plane type single-clack sliding valve is subjected to larger pressure difference, so that the friction force generated on the sliding surface is large, the action is insensitive, and the valve clack is easy to wear. It is also not adjustable in a small flow range due to structural disadvantages, and thus the economy is reduced when the machine is operated at low loads.
