Butterfly Valves

 

Aluminium Bronze Butterfly Valve, DESCRIPTION: ONS supplies Aluminium Bronze Butterfly Valves. Aluminium bronze butterfly valve are mainly used for seawater because of its property of resistance to corrosion, fatigue and galvanic corrosion in comparison with stainless steel and duplex stainless steel. Full Specification for Butterfly Valves: 1. Brief Definition: Butterfly valves are rotary valves in which a disc-shaped closure member is rotated through 90°, or approximately, to open or close the flow passage. 2. Material Specification: Body: WCB/WC9, Cast Iron, Ductile Iron, CF8/CF3/CF8M/CF3M, Aluminium Bronze Disc: Ductile Iron, Aluminium Bronze, CF8/CF8M Seat: NR, BUNA, EPDM, PTFE, NBR, Viton, SI, IIR, Metal Seated Shaft: Aluminium Bronze, SS410, SS304, SS316, Carbon Steel 3. Standards: API609, ANSI B16.1, ASME B16.9 4. Size: 2" ~ 64" (DN50 ~ DN1600)

Cast Iron Butterfly Valve, DESCRIPTION: ONS supplies Cast Iron Butterfly Valves. Cast iron butterfy valves are mainly made of the most economic material -- cast iron. They are widely used in low pressure water and sewage treatment systems. Full Specification for Butterfly Valves: 1. Brief Definition: Butterfly valves are rotary valves in which a disc-shaped closure member is rotated through 90°, or approximately, to open or close the flow passage. 2. Material Specification: Body: WCB/WC9, Cast Iron, Ductile Iron, CF8/CF3/CF8M/CF3M, Aluminium Bronze Disc: Ductile Iron, Aluminium Bronze, CF8/CF8M Seat: NR, BUNA, EPDM, PTFE, NBR, Viton, SI, IIR, Metal Seated Shaft: Aluminium Bronze, SS410, SS304, SS316, Carbon Steel 3. Standards: API609, ANSI B16.1, ASME B16.9 4. Size: 2" ~ 64" (DN50 ~ DN1600)

Lug Type Butterfly Valve, DESCRIPTION: ONS supplies Lug Type Butterfly Valves. Lug type butterfly valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using two sets of bolts and nuts. The valve is installed between two flanges using a seperate set of bolts for each flange. Full Specification for Butterfly Valves: 1. Brief Definition: Butterfly valves are rotary valves in which a disc-shaped closure member is rotated through 90°, or approximately, to open or close the flow passage. 2. Material Specification: Body: WCB/WC9, Cast Iron, Ductile Iron, CF8/CF3/CF8M/CF3M, Aluminium Bronze Disc: Ductile Iron, Aluminium Bronze, CF8/CF8M Seat: NR, BUNA, EPDM, PTFE, NBR, Viton, SI, IIR, Metal Seated Shaft: Aluminium Bronze, SS410, SS304, SS316, Carbon Steel 3. Standards: API609, ANSI B16.1, ASME B16.9 4. Size Range: 2" ~ 64" (DN50 ~ DN1600)

Wafer Type Butterfly Valve, DESCRIPTION: ONS supplies Wafer Type Butterfly Valves. The wafer type butterfly valve is designed to maintain a seal against bi-directional pressure differential to prevent backflow in piping system designed for unidirectional flow. It accomplishes this with a tightly fitting seal, i.e. gaket, and O-ring. Full Specification for Butterfly Valves: 1. Brief Definition: Butterfly valves are rotary valves in which a disc-shaped closure member is rotated through 90°, or approximately, to open or close the flow passage. 2. Material Specification: Body: WCB/WC9, Cast Iron, Ductile Iron, CF8/CF3/CF8M/CF3M, Aluminium Bronze Disc: Ductile Iron, Aluminium Bronze, CF8/CF8M Seat: NR, BUNA, EPDM, PTFE, NBR, Viton, SI, IIR, Metal Seated Shaft: Aluminium Bronze, SS410, SS304, SS316, Carbon Steel 3. Standards: API609, ANSI B16.1, ASME B16.9 4. Size Range: 2" ~ 64" (DN50 ~ DN1600)

Sanitary Butterfly Valve, DESCRIPTION: ONS supplies stainless steel Sanitary Butterfly Valves. The sanitary butterfly valve, usually in stainless steel with sanitary level surface finish, are mainly applied to food processing, beverage, dairy and pharmaceutical industry. Full Specification for Butterfly Valves: 1. Brief Definition: Butterfly valves are rotary valves in which a disc-shaped closure member is rotated through 90°, or approximately, to open or close the flow passage. 2. Material Specification: Body: WCB/WC9, Cast Iron, Ductile Iron, CF8/CF3/CF8M/CF3M, Aluminium Bronze Disc: Ductile Iron, Aluminium Bronze, CF8/CF8M Seat: NR, BUNA, EPDM, PTFE, NBR, Viton, SI, IIR, Metal Seated Shaft: Aluminium Bronze, SS410, SS304, SS316, Carbon Steel 3. Standards: ANSI, DIN, BS, JIS 4. Size: 1/2" ~ 4" (DN15 ~ DN100)
