KITZ Type UB 10K/16K & Class 150Stainless Steel Butterfly ValvesDouble-eccentric kinematics, and all stainless steel bodies and trims guarantee high performancecorrosion resistant service for application of KITZ Type UB butterfly valves to chemical industries.

DESIGN FEATURES

LEVER OPERATED

●Double-eccentric kinematicsThe valves stem is designed eccentric to both the center of the seat ring (by X) and the center of the valve body (by Y), which makes the clearance C between the seat ring and the disc seat surface on its fully open position (Fig.1). Disc seating surface is spherically machined and contacts PTFE seat tightly thorough 360℃ for leak-free service. All these help minimize frictional wear of seat rings and reduce the valve operating torque considerably.

●Durable seat ringsSeat rings are made of PTFE with stainless steel supporter. Furthermore, double-eccentric kinematics relieve seat ring from damage or wear which is a rather usual problem of conventional butterfly valves, This makes the service life twice as long as rubber seated butterfly valves.

●Retightening of gland packingThere is a room between the gland and the lever or gear to allow retightening of gland boltings without trouble of disassembly of the lever or gear during plant operation. Another feature of KITZ Type UB butterfly valves (Fig.2). CAUTION

The following gaskets should be used for the installation of the valves into pipelines.[Type of Gasket]●Reinforced PTFE gasket (Jacketed gasket, Spiral Wound gasket or Metal gasket cannot be installed.)[Dimension of Gasket]●The dimensions of the gasket should comply with ASME B16.21. (Minimum gasket thickness is 3mm.)The valves cannot be installed to stub ends.UB is a unidirectional valve. The valve must be installed according to an arrow, provided on the side of the operator mounting flange. The arrow must point from the higher pressure side to the lower pressure side in the valve closed position.
