VIIPLUS CHINA SELF-LUBRICATING BEARINGS are typically used in valves, hydro power equipment, lifting equipment and many other applications. Valve manufacturers value the TEX stainless steel and PTFE grades due to their high load carrying capability and chemical resistance.
High temperature and load capabilities
Low friction coefficient
Excellent chemical resistance
Very low stick slip
BUTTERFLY VALVE BUSHINGS | Self-Lubricating Bearings - Fiber glide bushings
Self-lubricating bearing use in BUTTERFLY VALVE BUSHINGS & Bearings Offers an easily installed choice to cumbersome, multi-bolt wafer or lug-type flanged valves.
Maintenance-free bearings are used in common hydraulic fluid and
many types of water emulsion conditions, suitable for vane pumps,
gears, plunger pumps and motors.In addition to their excellent
frictional and anti-wear properties, they are stable and reliable
under required loads and speeds, making them suitable for many
hydrodynamic applications.
A cover bearing and integral seat bearing guide the stem assembly
for precise alignment with the seat.
For use in carbon steel, ductile iron, and plastic piping systems.
Handle butterfly valve simple structure, small size, light weight, only a few parts.And only need to rotate 90 ° can rapid opening and closing, simple operation, at the same time, the valve has good flow control characteristics.When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop through the valve is very small, so it has better flow control characteristics.
Available without handle, with gear operator, with lever lock handle and memory stop or with 10-position handle and memory stop
VIIPLUS is one of valve bushings & bearing manufactures with the advanced valve plant in China who can cover a complete bushings production in order to satisfy the demand and requirements of our clients.
All the valve's internal self-lubricating bearings are sliding bearings, the whole material the use of carbon steel PTFE liner.
Our bushings & bearing product range is covering many valve
types like: gate, globe, check, ball, butterfly, nuclear, subsea,
control, safety valve & wellhead equipment. All the indicated
valve bushings range is being operated within different industries.
The bushings majority is being used in the oil & gas, offshore,
chemical, power, nuclear, mining and air separation industry.
VIIPLUS is able to provide a complete solution of industrial valves bushings with a fully traceable and in-house quality control system. VIIPLUS proven stable quality, reliability and performance.
ROLLED DRY SLIDING BEARINGS (PTFE)
Absorbing and transferring radical forces
Fixing moving components to each other
Ensuring guidance accuracy with radial and axial movements over the entire service life
Material is designed to operate without supplemental lubrication and will perform excellent when lubrication is present. Low friction, low wear rate, good sliding characteristics and very low absorption are a few of the features of this material. VSB-10 bushings will support rotary, linear and oscillating motion.
1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact
surface for the rotating shaft. Minute partides of the PTFE layer
and the sintered bronze material combine to create a solid
lubricant film, which coats the shaft.
2. Sintered bronze powder thickness 0.20*0.35mm,A special
composition of powdered copper is thermally fused to the steel
backing. This contact layer acts as an anchor for the PTFE layer
and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel backing. Setting the foundation of the
bushings, the steel back provides exceptional stability, load
carrying and heat dissipation characteristics.
