150LB WCB Wafer Triple Eccentric Butterfly Valve
A 150LB WCB Wafer Triple Eccentric Butterfly Valve is an industrial valve designed for reliable flow control and shut-off in various applications, such as water, oil, gas, and chemical processing.
Offset Mechanism: The shaft is offset from the centerline of the pipe (first offset). The shaft is offset from the centerline of the disc (second offset). The sealing surface’s conical axis is offset from the shaft axis (third offset), creating an elliptical sealing profile. This reduces friction between the disc and seat, minimizing wear and ensuring tight sealing. -
DN200 WCB Wafer Triple Offset Butterfly Valve with Worm Gear
Triple Offset is specifical:
✔ Metal-to-metal sealing.
✔ Bubble-tight shutoff.
✔ Lower torque = smaller actuators = cost savings.
✔ Resists galling, wear, and corrosion better.

WCB Double Flanged Triple Offset Butterfly Valve
The triple offset WCB butterfly valve is designed for critical applications where durability, safety and zero leakage sealing are essential. The valve body is made of WCB (cast carbon steel) and metal-to-metal sealing, which is very suitable for harsh environments such as high pressure and high temperature systems. It used in Oil & Gas, Power Generation, Chemical Processing, Water Treatment, Marine & Offshore and Pulp & Paper.

Double Flanged Triple Offset Butterfly Valve
The triple eccentric butterfly valve is a product invented as a modification of the midline butterfly valve and double eccentric butterfly valve, and although his sealing surface is METAL, zero leakage can be achieved. Also because of the hard seat, the triple eccentric butterfly valve can withstand high temperatures and pressures. The maximum temperature can reach 425°C. The maximum pressure can be up to 64 bar.

Pneumatic Wafer Type Triple Offset Butterfly Valve
Wafer type triple offset butterfly valve has the advantage of being resistant to high temperatures, high pressure and corrosion. It is a hard seal butterfly valve, usually suitable for high temperature（≤425℃）, and the Maximum pressure can be 63bar. The structure of the wafer type triple eccentric butterfly valve is shorter than the flang triple eccentric butterfly valve, so the price is cheaper.

Lug Type Triple Offset Butterfly Valve
Lug type triple offset butterfly valve is a kind of metal seat butterfly valve. Depending on the working conditions and the medium, different materials can be selected, such as Carbon steel, stainless steel,duplex steel and alum-bronze. And the actuator can be hand wheel, electric and pneumatic actuator. And the lug type triple offset butterfly valve are suitable for pipes larger than DN200.

Butt Welded Triple Offset Butterfly Valve
Butt welded triple offset butterfly valve are good sealing performance,so it improve the reliability of the system. It has the advantage that:1.low friction resistance 2. Open and close are adjustable, labor-saving and flexible.3. Service life is longer that soft sealing butterfly valve and can achieve repeated on and off.4. High resistance for pressure and temperature.
