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.
• The lugged wafer pattern ensures precise self  centering of valve between mating flanges.
• Possibility of lower seat rating to obtain reduced operating torque and extended seat life for low operating pressures.
