??Hydraulic transmission of liquid pressure is used to transfer power. In the hydraulic system and hydraulic valve seal products, sealing device used to prevent leakage of working medium and outside dust and foreign bodies. The merits of the sealing device will directly affect the performance of hydraulic system.>>>Best sale products top quality o-rings

??If the hydraulic cylinder seal is bad, can cause internal and external leakage, leakage will cause the waste of working medium, machine and environment, and even cause the failure of the mechanism operation and equipment accidents. Leak can cause a sharp drop in volumetric efficiency of the hydraulic system, short of the required working pressure, can't even work. Therefore, hydraulic seals seal is very important in the hydraulic system.

??Hydraulic valve sealing ring can be used to prevent oil leakage gas, dust, such as hydraulic system and the outside world. Hydraulic cylinder, of course, it is impossible to achieve absolute seal. Because of the reciprocating motion of the piston rod, always out of the oil. However, this small leakage requirements as far as possible. On the contrary, if, when the reciprocating motion of the piston rod is not out of no oil, make the piston rod is in dry friction, it will affect the performance of the hydraulic cylinder and life. Hydraulic valve seals and sealing device is an important component of hydraulic equipment. Hydraulic valve seal reliability and service life of the work, is to measure the hydraulic system is an important indicator of good or bad.
