EX200-5 Hydraulic Control Valve Seals 4366959 HITACHI O Ring Kit

4366959 HITACHI Hydraulic Seal Kit EX200-5 Main Control Valve Seal Kit

O-ring seal ring is called O-ring for short. It is a kind of rubber ring with circular section shape. O-ring is the most widely used seal in hydraulic and pneumatic systems. O-ring has good sealing performance, which can be used in both static seal and dynamic seal; Not only can it be used alone, but also it is a basic part of many combined sealing devices. It has a wide range of appliions. If the materials are properly selected, it can meet the requirements of various media and motion conditions.

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, a retaining ring is set 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 O-ring for fixing, when the working pressure is greater than 32Mpa, the retaining ring is also required.
