Y-Type Strainers (ANSI 150#, 300#)

Kansei Wafer, Lug and Flanged Double offset butterfly valves are designed to ensure minimum seat wear, zero leakage shutoff throughout the full pressure range and Uni-Bidirectional to provide a long service life with minimum maintenance. “A major advantage of Kansei product is an International compatibility.”

The Superior two-piece stem design and double offset disc/stem design allows high cycling and eliminates seat deformation when the disc is in the open position. At the initial point of disc opening, the offset disc produces a cam action and pulling the disc from the seat. During opening, disc does not contact the seat which ensures the maximum seat service life with reduced operating torques. The first offset is by locating the stems downstream of the center line of the seat which allows 360-degree unobstructed sealing surface. The second offset is by locating the stems off-center of the vertical axis of the seat. As the valve closes, the camming action converts the rotary motion of the disc to a linear motion which effectively push the disc on seat. Mounting pads integrally casted which provides direct mounting of Gear box and Actuators on valves. Torque requirements of the Kansei High performance double offset valve is significantly lower. The seat is completely isolated from all contact with the line media which allows superior performance of valve with extended service life. Serrations of the seat retainer ring and body secure the seat assembly in place irrespective of disc position. Line media seals to Zero-leakage in both directions and seat is self-adjusting to absorb wear and temperature changes. Replacement of seat is also easy without disturbing the disc or stem. The seat design in such a way to ensure seal drop-tight and bi-directional at low to high pressure range. Seat incorporates a Stainless-Steel wire winding with U-shape envelope to provide better seat life. The wire allows flexibility in both direction of flow. Fire safe: Kansei High performance double offset valves having firesafe seat design options in wafer, lug and flange valves. Fire safe design combines superior performance, extended service life. In normal service, the fire safe design with Soft seat and Metal seat to ensure zero-leakage in both directions of line media flow in full rated pressure and temperature range. In the fire condition, soft seat will be destroyed either partially or fully by excessive heat and metal seat will take place to provide constant sealing. Fire safe packing arrangement with three rings of graphite to create a superior and high temperature sealing.
