Industrial Alsint Alumina Ceramic Sealing Ring Flange
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Alumina ceramic liquid control check valve is widely used in hydraulic circuit, but when applying this valve, the characteristics of the valve should be fully considered, otherwise the circuit will be unstable, especially in high pressure system, hydraulic control check valve The pressure of the p2 port is high before the reverse opening. In order to reduce the control pressure, hydraulic shock and noise in the hydraulic system, a hydraulically controlled check valve that also unloads the spool is used. The unloading valve can improve the performance of the hydraulic control check valve. The characteristic of the hydraulic control check valve is that when the hydraulic control check valve port k is in the absence of pressure oil, the pressure oil can only flow from the port p1 to the port p2. Can't reverse. When the control port k has the control pressure oil, the oil pushes the ejector rod by the control piston, and the ejector rod opens the unloading valve core, and the main valve core opens, and the two ports of p1 and p2 are connected, and the oil can be used in the two. Freely circulated in one direction, the unloading valve reduces the hydraulic shock, making the performance of the hydraulically controlled check valve more stable, but there is still impact or noise in the high flow high pressure system.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
