Oil-free bearings Description: 1, no oil lubrication or less oil lubrication, suitable for refueling or difficult to refuel the place, can be used without maintenance or less maintenance. 2, wear resistance, friction coefficient, long service life. 3, the right amount of elasto-plastic, stress can be distributed in the wider contact surface, improve the bearing capacity. 4, similar to the static and dynamic friction coefficient, can eliminate crawling at low speed, so as to ensure the accuracy of mechanical work. 5, can make machinery reduce vibration, reduce noise, prevent pollution, improve working conditions. 6, in the course of the operation can form a transfer film, play a role in protecting the grinding shaft, no bite axis phenomenon. 7, the hardness of the grinding shaft requires low, quenched and tempered shaft can be used, thus reducing the difficulty of processing related parts. 8, thin-walled structure, light weight, can reduce the mechanical volume. 9, the back of the steel can be plated a variety of metals, can be used in corrosive media; has been widely used in various mechanical sliding parts, such as: printing presses, textile machines, tobacco machinery, micro-motors, automobiles, motorcycles and agriculture and forestry machinery and many more.
Angle Valves
Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.
Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services.
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
