Design, Manufacturing and Testing Standards – Technology at a Glance

Kansei Double flanged Eccentric Large Butterfly valves are designed to accommodate Flange drilling JIS, ANSI, DIN, BS. Also providing dead-end service capability with downstream piping removed. Each size valve flange has been designed to have the maximum outside diameter and maximum thickness of the nominated flange standards. K35 type valves provides the robust features to ensure reliable performance and long service life.
“A major advantage of Kansei product is an International compatibility.”

The valve face to face in accordance with EN 558, BS 5155 Short, ISO 5752 Table 4, EN-593 and AWWA C-504, AWWA C-207. Mounting cast flange designed in accordance to ISO 5211.

The Replaceable Seat design meets the requirements of seat replaceability on field without special tooling, dismantling and removing the valve from line. Also provide better shut-off and longer service life. The seat is of a molded construction and fits easily into the body which also reduce seating torque with disc edge contours. The Seat is adjustable to optimize the required shut-off tightness to comply the torque both for unidirectional and directional operation.

The Eccentric design provides energy efficient flow control. Stainless steel disc edge protects against corrosion and eliminates the possibility of restricted sealing. Upper and Lower shaft bearings prevent shaft deflection and provide optimum guidance to increase the valve life. High strength and Full diameter Shafts remain dry and provides positive disc control with a minimum flow restriction.

Sleeve bearings are self-lubricated which allows valve installation with the shaft vertical or horizontal. Thrust bearings are provided with the adjustment to ensure good axial positioning of the disc due to forces applied by seat and shaft seals to the disc. The secondary seal is provided to seal the bearing area from environment, and it will also act as a primary seal in account of failure of primary seal, Rubber lining is additional option for this product.
