Tyco B30330EL 3" Butterfly Valve With Lever Lock & E-Gasket
The GRINNELL Model B303 Butterfly Valves provide for efficient control in piping systems of on/off or throttling/ balancing service, fluid flow, and bubble-tight shut-off. The valves are furnished with grooved ends for use with grooved couplings and can be easily adapted to flanged components utilizing GRINNELL Figure 71 and Figure 71H Class 150 Flange Adapters. The Model B303 Butterfly Valve with Grade “E” EPDM Disc Seal is temperature rated from -30ºF (-34ºC) to +230ºF (+110ºC). The 2 in. through 12 in. (DN50 through DN300) Model B303 Butterfly Valve with Gear Operator is a self-locking, traveling nut gear operator (2 in. through 8 in.) and segmented gearbox (10 in. through 12 in.) type. It is equipped with adjustable stop screws to lock the valve at the full open and shut positions. The 2 in. through 8 in. (DN50 through DN200) Model B303 Butterfly Valve (Ref. Figure 2) with Lever-Lock Operator has a throttling plate that provides throttling notches every 10º for manual control in balancing up to 90º 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. The lever operation accommodates at least 2 inches of clearance for insulation (Ref. Figure 2 dimensions). Flow may be from either direction and the valve may be positioned in any orientation. 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.
