Class 150 - Short Pattern - Standard Type

 
AUDCO Lubricated Taper Plug Valve has been successfully used in a variety of services because of its unique in-line maintenance capability* The Plug and Body seating surfaces* which are lapped and matched, are not exposed to the line fluid; this confines corrosion and erosion to less critical areas. Sealing is further enhanced by a specially developed plug sealant, charged evenly around the seating surfaces. Plugs are impregnated with a PTFE based anti-friction agent - 'SUPER Ix>MiT which provides greater wear resistance and ensures low consistent operating torque. SL'PKR LoMu uLso enhances resistance to seizure.
 
OPERATION MATERIAL SPECIFICATION


Short Pattern Carbon Steel Lubricated Taper Plug Valves uplo 8* arc all supplied with square stems suitable for wrench operation (LW Scries). Wrenches, as required, should however be ordered separately. Valves 6* to I0" can be offered with Light Duty Gear Units (LO Series). Valves 6" and above can also be offered with Heavy Duly Worm Gear Unit (LG Scries). Wrenches and Gear Units should be selected as determined by (he service conditions, which influence the operating torque. Gear Units as ordered are installed on the valves and supplied

Valves can also be offered wilh Carbon Steel Plug (LS/LGS/LGS Scries)

As a standard. Carbon Steel Plug Valves arc supplied with AUDCO 733 Plug sealant which is suitable for most hydrocarbon services. On request, plug sealant from a wide range offered, can be supplied to suit the nature of service. It is recommended that you consult us before selecting (he plug sealant for a new service.
