Tianjin, China
5000PCS/Month
L/C, T/T
Plywood Case
5 Piece
Name:Worm Gear Lug WCB Triple Eccentric Butterfly Valves
Material:Body: WCB; Disc: 6A, Stem: 316. Seat: surface STL,Sealing ring: SS316+STL
Nominal Pressure:150LB
Nominal Diameter:DN250
End Connection:Lug
Structure:Triple Eccentricity
Operation:Worm gear
Valve type:Industrial Valve
Working Temp.:-100℃~+425℃
butterfly valve for chilled water system
The stem is offset on both the X (1)and Y (2) axis of the valve's
center line. This produces a cam一like motion. The third offset (3)
consists of an inclined conical profile machined into the valve
sealing surface. This allows rotary engagement and disengagement
of the seat and seal ring without interference. All rubbing
between seat and seal ring is thereby eliminated. Once the seat
and seal ring are fully engaged torque is applied in order to
create a bi一directional, zero leakage, metal-to一metal seal. For
this reason, triple offset valves are often defined as "torque" seated
rather than”position” seated as in the case of resilient or high performance products.
Multi-layer disc sealing ring adopts ss304 and graphite laminated, sealing
by the inside graphite, applied for low and middle pressure, as recycle water,
swage treatment, city building, etc.
