Hydraulic Seal Kit ZX240-3 Main Control Valve Seal Kit

O-ring is an extrusion seal. The basic working principle of extrusion seal is to rely on the elastic deformation of the seal and cause contact pressure on the sealing contact surface. If the contact pressure is greater than the internal pressure of the sealed medium, there will be no leakage, otherwise there will be leakage.

Use of O-ring O-ring is widely used in the joints of various hydraulic and pneumatic parts, pipe joints, cylindrical surfaces and flange surfaces. For the O-ring used in the process of movement, when the working pressure is greater than 9.8MPa, such as unidirectional compression, set a retaining ring on the other side of the pressure direction of the O-ring; In case of two-way compression, place a retaining ring on both sides of the O-ring. In order to reduce friction, wedge-shaped retaining ring can also be used. When the pressure liquid acts from the left, the right retaining ring is pushed up, and the left retaining ring does not contact the sealed surface, so the friction is reduced. In general, the use of retaining ring will increase the friction of sealing device, and wedge retaining ring is of great significance to reduce this friction. For the fixed O-ring, when the working pressure is greater than 32Mpa, the retaining ring is also required.
