Our range
of butterfly valves are used for regulating the flowing fluid with the aid of a section pipe. It is considered to be very similar to the operation of ball valve, which is also a fluid regulating instrument. PTFE butterfly valves has the plate within the flow and hence pressure drop is always induced in the flow irrespective of the valve placement. Some of the features of our butterfly valves are:
- Good elongation
- It has folding endurance
- Upper service temperature
- Arc resistance.
Compact Design: Fully flow control in quarter turn operation. Bidirectional 100% tight shut off. Both shaft mounted in bearing supports for easy operating torque. Suitable for mounting between all standard flanges.
Not require any type of gasket packing to is tall.

A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required.
