Product Information

A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk.

The Butterfly Valve, one type of which may be used in a variety of systems aboard ship. 
These valves can be used effectively in freshwater, saltwater, lube oil, and chill water systems aboard ship. The butterfly valve is light in weight, relatively small, relatively quick-acting, provides positive shut-off, which can be used for throttling.

A Resilient Seated butterfly valve has a body, a resilient seat, a butterfly disk, a stem, packing, a notched positioning plate, and a handle or gear. The resilient seat is under compression when it is mounted in the valve body, thus making a seal around the periphery of the disk both upper and lower points where the stem passes through the seat. Packing is provided forming a positive seal around the stem for added protection in case the seal formed by the seat could become damaged.

To close or open a butterfly valve, turn the handle only one quarter turn to rotate the disk 90 degrees. Some larger butterfly valves may have a handwheel that operates through a gearing arrangement to operate the valve. This method is used especially where space limitation prevents of a long Lever.

Butterfly valves are relatively easy to maintain. The resilient seat is held in place by mechanical means, and neither bonding nor cementing is necessary, because the seat is replaceable, the valve seat does not require lapping, grinding, or machine work.

We can Supply a wide range of Butterfly Valves covering Resilient Seated Butterfly Valve and Metal Seated Butterfly Valve: Wafer Lug Type Butterfly Valve, Double Flanged Butterfly Valve, Eccentric Butterfly Valve, Ventilation Butterfly Valve, Flexible Butterfly Valve, High Performance Butterfly Valve, Muti-layer Butterfly Valve, Butt-welded Butterfly Valve, Hydraulic Counterweight Butterfly Valve and Fully Body Lining Butterfly Valve etc.
Materials range from conventional cast Iron, ductile iron, Cast steel or forged steel to special alloy materials like Monel, Inconel, Hastelloy or Duplex steel.

All of the Butterfly Valves are designed, manufactured and tested to API, ASTM, ANSI, JIS, DIN and BS Standards.
