??Rubber O-rings in the valve in use

??Rubber O-ring as widely used in all walks of life sealing element member, rubber O-ring can be installed in various types of valves at a predetermined temperature, pressure, and various liquid and gaseous media at rest or in motion from the state seal protection.

??Rubber O-ring sealing member is in the form of a variety of suitable sealing rubber O-ring on the end face of the valve stem and can effectively prevent the leakage of all types of media, to ensure the normal operation of the valve system. Rubber O-ring mounted on the end surfaces of which belong to the static sealing effect, is mounted on the valve body and valve stem hole genus dynamic sealing effect. Two types of sealing effect fully meet the design requirements of the ball. Sport rubber O-ring friction is small, can be achieved without leakage problems, a small amount of leakage may play a lubricating effect.

??Gas valve leak caused a fire caused by an accident, then the rubber O-ring to reflect its value, a gas leak embedded rubber O-ring, can effectively prevent the leakage of the valve clearance is less than 0.001μm, thereby zero leakage, so it is particularly suitable for special occasions conditions need gas, dust and other media.

??Rubber O-rings or less at a temperature less than 200 ?, at this time whether it is a static seal or dynamic seal valve selection rubber O-rings as seals, fully meet the design parameters. Different materials can be applied to different temperatures inside.

??Xu Xinhua Rubber Products Company Reminder: Common Viton Operating temperature range -25 ~ 240 ?, and Kalrez special grades can withstand a constant temperature of 300 ? or 340 ? high temperature instantly without hardening and swelling failure. Silicone rubber material is one of the strongest resistance to low temperature materials, although it can reach -100 ?, but its low tensile strength, poor wear resistance.
