Product Description

Product Description

A hydraulically controlled check valve is a valve that can make the check valve flow in the opposite direction by controlling the fluid pressure. This kind of valve occupies an important position in the hydraulic support equipment of coal mining machinery. The difference between the hydraulic check valve and the ordinary check valve is that there is an additional control oil circuit, when the control oil circuit is not connected to the pressure oil, the hydraulic check valve works like an ordinary check valve, and the pressure oil only flows from the oil inlet to the oil outlet, and cannot flow in reverse. When the control oil circuit has a control pressure input, the piston ejector rod moves to the right under the action of pressure oil, and the check valve is opened with the ejector rod to make the inlet and outlet ports connected. If the oil outlet is larger than the oil inlet, the oil can flow in the opposite direction.
