See individual products for appropriate approvals. 12/8/09 22:32 Page 2 Jet range Butterfly Valves have a reputation for delivering well designed, quality engineered, user-friendly products for industrial and commercial applications. Features Polyacetal stem bearing NBR (Buna-N) or EPDM O-ring ISO90001:2000 Stainless steel stem Valves and actuated packages are designed, manufactured and assembled under ISO9001:2000 Ductile iron body with protective paint coating Valves with EPDM seats have WRAS approval. Water Regulations Advisory Scheme (WRAS) is the UK Water Industry’s approval scheme. Products approved by the scheme have been shown to comply with the requirements of the Water Supply (Water Fittings) Regulations 1999 and amendments. All Valves Comply with the 'ATEX Equipment Directive' 94/9/EC. Atex is the European Community Directive covering equipment intended for use in potentially exposive atmospheres. 2 NBR (Buna-N), EPDM or HT-EPDM seat firmly molded-in (bonded) to valve body Ductile iron with ENP or stainless steel disc Zinc die-cast plug with chromate coating Bonded Seals Moulded-in (bonded) seat construction is used throughout the range. This assures maintenance free liners and allows trouble-free use on high velocity (up to 4m/s) and vacuum service. Spherical Seat and Disc Design Valves are CE marked to PED 97/23/EC where allowed or comply under Sound Engineering Practice for use with Groups I and II Gases and Liquids, subject to compatibility of materials of construction with line fluid. Integral ISO 5211 Actuator Mounting Flange The ISO mounting flange allows simple addition of electric or pneumatic actuators, in most cases mounted directly onto the valve. Contents page Introduction Manual Semi-Lugged Valves Manual Fully-Lugged Valves Electrically Actuated Valves Pneumatically Actuated Valves Performance Charts Flange Bolting Data Valve seats are of a spherical design where they contact the top and bottom stems, prolonging valve life. 2-3 4-5 6-7 8 9 10 11 Low Valve Operating Torque The low torque design contributes to the valves extended working life and permits the use of smaller actuators, bringing the benefit of savings in both initial purchase price and energy consumption. Emission-free Stem Sealing Mechanism Tight contact between the disc and seat, combined with a rubber O-ring assembled around the top stem ensures that the risk of external leakage is minimised. End of Line Service Jet range butterfly valves retain their full pressure rating when used in a dead end (end of line) service with the downstream flange removed (on fully-lugged valves). A downstream flange is recommended when continuously used in a dead end service for more than 96 hours. Warning During the manufacturing process, lubricants are applied to discs and seats to protect their surfaces, they cannot be used for paint, oxygen or similar processes without being degreased to an appropriate standard. Introduction Orientation Valves can be installed in any orientation, however, when used with viscous liquids, they should be positioned with the stem horizontal and the disc opening in a downstream direction.

Body Styles & Seat Materials Gearboxes Valves with Nitrile Seats Nitrile (NBR or Buna-N) For Air, Gas, Water and Mineral Oils • Fig. 611 Nitirile, Multi-Flange Semi-Lugged Body • Fig. 614 Nitrile, Fully Lugged Body Drilled & Tapped for PN16 Flanges Valves with EPDM Seats Manually operated gearboxes are standard for 250mm and 300mm valves. They are an alternative to levers on valves up to 200mm where their multi-turn action ensures that they can be neither opened nor closed too quickly for a particular process or service. They are additionally used to ease operation on viscous services. Our gearboxes are lightweight, compact, colour-matched to the valves and have position indicators on top of their casing. Stem Extensions Stem extensions, with or without guide brackets and/or universal joints are available upon request. Electric Actuation We can supply either on/off or modulating actuators for any voltage, fitted to any quarter-turn valve. Actuators are designed and built to the same exacting standards as our valves.Turn to page 8 for more details.

The simplest and most economic method of operation, offering quick quarter-turn action. Our levers can be locked into any of ten positions by passing the hasp of a padlock through the hole in the lever trigger. Manufactured from lightweight aluminium, our levers have a bright orange finish to help determine valve operating position where valves are located in areas of poor visibility or where access is difficult. Available for valves up to 200mm. 9/32" hasp padlocks supplied separately; • H65025 Keys Alike, • MH65035 Keys Differ 3 electric actuation Pneumatic Actuation Because of their low operating torques, Jet range butterfly valves are ideal for automating.
