1 Technical Services GRINNELL Model B0 and Model BN0 Grooved End Butterfly Valves with Gear Operators or Lever-Lock Operators General Description The GRINNELL Models B0 and BN0 Butterfly Valves are available with either a Gear Operator or a Lever-Lock Operator (igures and ). They provide for efficient control in piping systems of on/off or throttling/balancing service; fluid flow; and bubble-tight shut-off. The Model BN0 Butterfly Valve is specifically NS Approved to Annex G. This valve is suitable for use with stainless steel domestic water systems The Model B0 or Model BN0 Butterfly Valve with Gear Operator is a self-locking, worm gear type. It is equipped with adjustable stop screws to lock the Handwheel position. The Model B0 or Model BN0 Butterfly Valve with Lever-Lock Operator has a throttling plate that provides throttling notches every 0 for manual control in balancing up to 90 or to shut off service. The Lever may be pad-locked in any one of the positions, including opened or closed, by virtue of a locking hole located in the handle and lever. low may be from either direction and the valve may be positioned in any orientation. The valve is furnished with grooved ends for use with grooved couplings and can be easily adapted to flanged components utilizing GRINNELL igure Class 0 lange Adapters. The body and disc construction provides for increased strength and durability. The disc seal and body coatings are compatible with a variety of chemicals and temperature ranges. Contact your GRINNELL Representative for specific recommendations on seal and coating selections. WARNING Never remove any piping component nor correct or modify any piping deficiencies without first de-pressurizing and draining the system. ailure to do so may result in serious personal injury, property damage, and/or impaired device performance. It is the Designer s responsibility to select products suitable for the intended service and to ensure that pressure ratings and performance data are not exceeded. Material and gasket selection should be verified for compatibility with the specific application. Always read and understand the installation instructions. The GRINNELL Models B0 and BN0 Butterfly Valves described herein must be installed and maintained in compliance with this document, in addition to the standards of any other authorities having jurisdiction. ailure to do so may result in serious personal injury or impair the performance of this device. Owners are responsible for maintaining their system and devices in proper operating condition. The installing contractor or device manufacturer should be contacted with any questions.

This turning force in a butterfly valve is determined by three factors. riction of the disc to seat for sealing friction Dynamic torque Breakaway Torque is the total of the torques resulting from bearing friction and seat/disc interference friction at a given pressure differential. This value is normally the highest required torque to operate a valve and is used in sizing actuators. The torques listed are valid for water and lubricating fluids at ambient temperature. or dry and nonlubricating fluids, contact a GRINNELL Technical Service representative. Butterfly valves, sizes Inch and larger, when used on liquids, show a marked increase in dynamic torque that tends to close the valve. or this reason, gear operated or actuated valves are recommended. The torque values listed in igure apply to EPDM. When calculating torques for Nitrile or luoroelastomer, multiply listed torque by.. Installation NOTICE All replacement parts must be obtained from the manufacturer to assure proper operation of the valve. In piping systems, butterfly valves should be located where operation, inspection, and maintenance are readily accessible. When a valve closes hard, it may be due to debris lodged in the sealing area. This may be corrected by backing-off the handle or handwheel and closing it again, several times if necessary. Never force the valve to seat by applying a wrench to the handwheel or extension to the lever, as it may distort the valve components or score the sealing surfaces. To prevent rotation of the valve, the Model B0 Butterfly Valve is recommended to be installed with rigid type couplings such as the GRINNELL igure Coupling. If flexible couplings are used, additional support may be needed to prevent rotation.
