Flange Butterfly Valve with Supporting Legs
Usually when the nominal size of the valve is greater than DN1000, our valves come with support legs, which makes it easier to place the valve in a more stable way. Large diameter butterfly valves are usually used in large diameter pipelines long with you over to control the opening and closing of fluids, such as hydroelectric power stations, hydraulic stations, etc.

NBR Seat Flange Butterfly Valve
NBR has good oil resistance, usually if the medium is oil, we will preferably choose NBR material as the seat of the butterfly valve, of course, his medium temperature should be controlled between -30℃~100℃, and the pressure should not be higher than PN25.

Electric Rubber Full Lined Flange Type Butterfly Valve
The fully rubber-lined butterfly valve is a good addition to the customer’s budget when they cannot afford to use 316L, super duplex steel, and the medium is slightly corrosive and in low-pressure conditions.
-
Concentric Cast Iron Full Lined Butterfly Valve
Concentric PTFE Lining Valve also known as fluorine plastic lined corrosion resistant valves, are fluorine plastic molded into the inner wall of the steel or iron valve bearing parts or the outer surface of the valve inner parts. Fluorine plastics here mainly include: PTFE, PFA, FEP and others. FEP lined butterfly, teflon coated butterfly valve and FEP lined butterfly valve are usually used in strong corrosive media.
-
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.

Worm Gear DI Body Lug Type Butterfly Valve
Worm Gear also called gearbox or hand wheel in butterfly valve. Ductile Iron body lug type butterfly valve with worm gear is common used in water valve for pipe. From DN40-DN1200 even larger lug type butterfly valve, we also can use the worm gear to open and close the butterfly valve. Ductile Iron body is suitable for a wide range of medium.Such as water, wast water,oil and etc.

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.
