Product List |
The Triple Offset Butterfly Valves has a metal seated structure that allows this valve to be used for extremely high working pressure and temperature.
Thanks to its triple eccentric structure, externally is applied a
seal specific pressure on the shaft driving torque in order to
allow the valve disc and seat to form an oblique con seal surface.
In this way the leakage (usually caused by ageing, cold-flow
characteristics and losing elasticity of the seat) is avoided.
Different face to face available according to your request (example
ISO5752 Series 13, EN 558 Series
Furthermore, in order to eliminate mechanical abrasion of seat
because of the disc rotary, the disc of the valve has been arranged
in order to touch the seat tightly only in fully closed position.
This valve can be supplied with bare shaft ISO 5211 mounting pad
connection or can have several operation type: Manual, Worm Gear,
Electric, Pneumatic, Hydraulic. In addition it can provide a
fireproof stopper driver.According to your request, the Triple Offset Butterfly Valves can
be provided Lug, Wafer or Flanged type.
Performance:
1. compact structure, small volume, free operation,convenient maintainance.
2. 3D Eccentric Seal Principle Design. so that full seal can be reached&air pressure leakage test is Zero.
3. Stainless steel material is used for seal, special process is adopted during manufacture, so that it has characristic of high temperature and corrosion reistant, and long service life
4.Large area of flow, small flow resistance index, large flow capacity
5. Applied in power station heat supply system&catalyzing,cracking main fan pipe
