Huade 2FRM 2FRM5 2FRM6 2FRM10 2FRM16 Speed Control Valve Manual Flow Valve 2FRM5-31B/6Q 2FRM5-3X-3.0

What is the combination of Huade Beijing HUADE speed control valve 2FRM5-31B/1.2QB? 2FRM5-31B/6QB 2FRM5-31B/10QB 2FRM5-31B/15QB The throttle valve is used to regulate the flow passing through, and the constant differential pressure reducing valve automatically compensates the influence of load change, making the pressure difference before and after the throttle valve a constant value, eliminating the influence of load change on the flow. The pressure in front of and behind the throttle valve is respectively led to the right and left ends of the pressure reducing valve element. When the load pressure increases, the hydraulic pressure acting on the left end of the pressure reducing valve element increases, the valve element moves to the right, and the pressure reducing port increases

working principle

1. Work interest cost management

Working principle diagram of slide valve directional valve: when the valve core moves to the right for a certain interval, the pressure oil input by the hydraulic pump flows from port P of the valve through port A to the right chamber of the hydraulic cylinder, the oil in the right chamber of the hydraulic cylinder returns to the oil tank through port B, and the piston of the hydraulic cylinder moves to the right; On the contrary, if the valve core moves to the right for a certain interval, the liquid flow reverses and the piston moves to the left. Its graphical symbol.

2. Structure of reversing valve

1) Manual directional valve

Manual lever shall be used to rotate the position of variable valve element, which is called implicit reversing. There are two kinds of positioning: spring active reset (a) and spring gang ball (b).

2) Flexible directional valve

The flexible directional valve, also known as range valve, is important for controlling the stop of mechanical moving parts, and also helps the baffle iron or concave wheel of the device on the workbench force the valve core to move, so as to master the flow direction.

3) Solenoid directional valve
