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.

Design, Manufacturing and Testing Standards – Technology at a Glance

Kansei Wafer and Lug Centric Bi-directional butterfly valves are designed with few moving parts to provide a long service life with minimum maintenance. “A major advantage of Kansei product is an International compatibility.”

The Superior single piece through shaft design in One-piece body is a reliable and long-life solution for difficult conditions. Valves are with light weight and ideal economic solution for general purpose applications. Lugged valve gives alternative solution where flanged valves are considered and restrictions of space and cost. The Replaceable Seat design isolates the line media connection from body and stem. Replaceable seat design with inbuild molded O-ring eliminates the need for gaskets between the flanges and the valve. Also serve as the flange gasket to make valve more capable. Seat is convenient and economical for field replacement. Sealing is formed by preloaded contact between disc and seat. Shaft seal is suitable for pressure-vacuum service which is also self-adjustable, non-corrosive and heavy duty to absorb the thrust and extends valve cycle life. The Disc hub-edge profile is spherically machined and rounded manually with polishing to provide full concentric seating without obstruction to flow which gives maximum seat life, minimum torque and bubble tight shut-off. Disc-Screw connection with disc is positive, stronger and allows quick and easy disassembly.

Design, Manufacturing and Testing Standards – Technology at a Glance

Kansei PFA/PTFE Lined Centric Bi-directional Butterfly valves are designed to ensure a tight fit around the disc for bubble tight shut off in both direction and provide a constant torque with no maintenance. “A major advantage of Kansei product is an International compatibility.”

The Exceptional Design of one-piece thin disc stem lined with 3mm molded PFA providing high Kv value. The liner and disc are the only two valve parts in contact with the medium. Kansei improved design of disc leading to less deflection at higher pressure and tighter in line seal and for stem sealing system. Primary shaft sealing by preloaded contact between disc and liner hub and the secondary shaft seal by oversizing the shaft diameter in relation to the shaft hole in the liner. The liner and disc are molded and machined to close tolerances to provide low torque, less stress and deformation using opening and closing. PTFE atmospheric seat protects internal components from atmospheric corrosion and provides locating ring for actuator mounting. Fully encapsulated bottom shaft eliminates potential leak path at bottom of valve and eliminates the necessity for further sealing elements
