IVGK-25 General Purpose Rubber
Lined Butterfly Valves
Key Features
Unique triple sealing system for shaft sealing, eliminates any
fugitive emission or secondary leakage.
Self lubricated PTFE lined bearings for both drive end and
non-drive end shaft ensures minimum bearing friction torque.
Seat liner extending on to the flange contact faces, eliminates
the need for separate flange gaskets during installation.
Controlled compression of the gasket face to offer optimum
sealing & prevent gasket face crushing failure.
Bi-directional valve with tight shut off sealing capability to hold
vacuum to rated pressure in either direction.
Excellent adaptability for actuated operation through
standardised top flange mounting dimensions for actuator fitment.
Suitability for ON /OFF as well as throttling duties.
Choice of seat and disc materials to suit media conditions and
service requirements.
Adaptability to fit between companion flanges of all popular
flange standards for the wafer style body.
Possibility of lower seat rating to obtain reduced operating
torque and extended seat life for low operating pressures.
