    Variety of Extension Lengths Available Bonnet extensions available in varied lengths to suit

    specific service requirements.

    Compact Body Design Allows rapid cooling to cryogenic temperatures.

    Eccentric Disc and Offset Shaft No seat/disc contact in the open or intermediate

    position. Eliminates wear points at top and bottom of seats

    for higher cycle life.

    Reduces torque requirements, allowing for smalleroperators.

    Easy Maintenance Simply remove body insert and replace seat

    disassembly of disc and shaft is not required.

    Single Source Responsibility Valves, actuators, and accessories from one source

    with accessories fully mounted.

    Available with electric, manual gear, and pneumaticdouble-acting or spring-return actuators and avariety of accessories including limit switches andsolenoids.

    CE Marked Versions Available CE marked and documented valves that conform to

    the European Pressure Equipment Directive (PED)97/23/EC are available in ANSI Class 150/300/600.Operating torques, construction options and valvedimensions are exactly the same as the standardANSI 150/300/600 offering. The applicable sizes forCE marked values are shown in table to left.

    FEATURESField-proven Flexible-Lip Seat Design

    Tight shut-off in either direction. Contact Metso forshut-off performance details.

    Composite seat in 3 12 (DN 80 300), K815, K830and all K860 valves with metal carrier and PTFE orPCTFE insert, assures tight sealing over a wide rangeof pressures and temperatures.

    Single-Piece PCTFE seat in 14 (DN 350) and largerK815 and K830 valves is designed with a uniqueflexible lip for positive, long-lasting shutoff.

    Seat Ratings

    Seat ratings are based on the differential pressure with thedisc in the fully closed position. Up to +100F (38C) theratings for the seats are the same as the body ratings.Above 100F, the seat ratings drop lower than the body rat-ings and are limited by temperature. (See graph below).Consult the factory if applications exceed these tempera-tures.

    Body Ratings

    These are maximum working-pressure ratings of the valvebody only. The seat ratings shown in the table to the leftdetermine the practical pressure limitations according toactual service conditions. Test pressures are for hydrostatictest with disc open.

    Flow Data

    The table below provides information on flow capacity forthe Wafer-Sphere cryogenic valves covered in this bulletin.The Cv values represent the flow of water at 60F throughthe valve in U.S. gallons per minute at a pressure drop of 1psi. The metric equivalent, Kv, is the flow of water at 16Cthrough the valve in m3/hr at a pressure drop of 1 kg/cm.To convert Cv to Kv, multiply by 0.8569.

    BONNET EXTENSIONS

    Cryogenic valves are made from standard stockedcomponents with extension lengths available, in 2-inchincrements, within the ranges shown in the dimensionaltables on pages 4 13 (see dimensions K1 and K2). The K2lengths require larger shafts as shown in the dimensiontables. Other lengths are available on application.

    Under the specified operating limits of the valve, all bonnetextensions are structurally capable of supporting the weightof the actuator in all possible installation orientations.

    OPERATING HANDLES AND ACTUATORS

    As an option, handles are available for small-size cryogenicWafer-Sphere high-performance butterfly valves. High linepressure may create high enough forces to pull a manual

    handle out of an operator's hand. Therefore, it is recom-mended that manual gear, pneumatic, or electric actuatorsbe used for valves larger than tabulated below.
