REPLACEABLE SEAL BUTTERFLY VALVE
	It is a valve for use in power generation plants, municipal water treatment and industrial applications.
	Designed basically for the waterworks industry, is in full compliance with ISO 5752, with actuator flange acc, ISO 5211.
	It is a cast double flanged butterfly valve, which can be drilled according to various flange standards (JIS, BS, DIN, ANSI) and also provide dead-end service capability with down stream piping removed.
	Body and disc protective coatings or rubber linings are available for sea water or corrosive services as well as for external protection.
The special seat and disc edge contours reduce seating torque, provide better shut-off and longer service life.
For sizes 700mm and up, the seat is adjustable in order to optimise the required shut-off tightness with the accompanying torque, both for uni-directionl of bi-directional operation. This set is replaceable without special tooling, dismantling or removing the valve from the line.
For sizes 700 mm and up, a stainless steel disc edge resists against corrosion and avoids encrust build-up for consistent sealing.
Full diameter stub shafts remain dry and provide a positive disc control with a minimum flow restriction.
High strength stub shafts have full 1-1/2 dia, penetration into disc-hubs with close tolerance-fit.
Mounting base plates for easy installation available.
Self lubricating sleeve bearings allow valve installation with the shaft horizonal or vertical. Non metallic bearing material has an extremely low friction coefficient to reduce operating torques and eliminate galvanic corrosion.
