General application

The Figure 56 design offsets an excellent, low cost solution for municipal water treatment, desalination, power generation and industrial applications.

 

Features and Benefits

● Designed basically for the waterworks industry, Fig.56 in full compliance with ISO 5752, ISO-13 with actuator flange acc. ISO 5211.
● It is a cast double flanged butterfly valve, which can be driled acc. various flange standards (JIS, BS, DIN, ANSI) and also provide dead-end service capability with down strearm piping removed.
● Body and disc protective coatings are available for sea water or corrosive sevices as for external pro tection.
● The low profile one-piece seat provides an un-interrupted 360° seal and is fully adjustable to tightness regardless of changing piping stresses. No bonding to the body is required. The seat is replaceable without special tooling, dismanting or removing the valve from the line.
● The special seat and disc edge contours reduce seating torque, provide better shut-off and longer service life.
● 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
● High strength stub shafts have full 1 1/2diam. penetration into disc-hubs with close tolerance-fit.
