BALL VALVE AL 33 - Masterstar

Transcription

1 Ref..6_UK04/0. Telephone LL VLV L 33 Masterstar esign The L 33 is a threepiece ball valve made of stainless steel or carbon steel. The valve has an antistatic, blowoutproof stem and a fullyfloating ball, and is iresafe approved. The valves are provided with mounting plate for actuator in accordance with ISO 5. The L 33 is available in sizes with full bore and with reduced bore, pressure ratings PN 660 with threaded and welding connections (PN 6 with flanged connections). Temperature range of to +4, depending on the seal material.

Temp. range: 60 to +30. = LRIN This LRIN seal has excellent dimensional stability to resist extrusion at high pressures. Temp. range: to +95. = VSPL The VSPL seal is excellent for high temperatures and high pressures and has good resistance to chemicals. Temp. range: to G = 00% graphite material for seat seals and body seals. Selflubricating. xcellent for high or low temperature applications, but at low pressures. pplications: Steam and lowtemperature cryogenic service, although not for oxygen. Temp. range: to +4. K = KL KL seal for low temperatures. This material is similar to PT but has better mechanical properties and good resistance to nitric acid, hydrofluoric acid and liquid oxygen. pplications: ryogenic service and high pressures. Temp. range: to +. T = 00% PT xcellent resistance to chemicals. Minimizes the torque. Used in the food industry and for vacuum. Temp. range: 0 to +0. or further information, see the separate sheet entitled Pressure/ Temperature graph.

Variants/Options Versions for low temperatures, extended stem, lockable design, NSI flanges, etc. are available to special order. Installation and maintenance The valves shall be installed in the open position. Spotweld the valve in the required position, and then release and remove all bolts. Lift the valve body out of the pipework. Protect the ball and the PT seals from weld spatter by covering them with a piece of cloth or the like. Weld the valve in position. Leave the valve to cool down before refitting the valve body. Note. or sizes from inclusive with full bore and from inclusive with reduced bore, the valve should be installed as a unit, i.e. the valve body must not be removed when the valve ends are welded to the pipework. all valve L 33 oubleacting oubleacting Singleacting Singleacting lectric L 7 L 79 L 77 L 79 ull Reduced Opening Type Nm Type Nm Type Nm Nm Type Nm Nm Type Nm bore bore torque, towards towards towards towards Nm 90 o 0 o 90 o 0 o SR 0SR SR 0SR SR 3 SR SR 3 SR SR 75 4 SR SR SR SR SR SR 5 35SR SR 5 35SR SR 30 SR Head Office xel Larsson Maskinaffär, Truckvägen, P.O. ox 5, S94 Upplands Väsby (Stockholm), Sweden.
