Cast Iron 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 (he 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 LoMu’ which provides greater wear resistance and ensures low consistent operating torque* SUPER LoMu also enhances resistance to seizure.
 
OPERATION


Short Pattern Lubricated Taper Plug Valves up to 10" arc all supplied with square stems suitable for wrench operation (LW Series). Valves 6" to 10" can be offered with Light Duty Gear Units (LO Series). Valves 6" and above can be offered with Heavy Duty Worm Gear Unit (LG Series), Wrenches and Gear Units should be selected as determined by the service conditions, which influence the operating torque. However wrenches should he ordered separately whereas gear units as ordered are installed on the valves and supplied. Valves can also be offered with Carbon Steel Plug (LWS/LOS/LGS Series)

As a standard. Cast Iron Plug Valves arc supplied with AUDCO 731 Plug sealant which is suitable for most services other than acid solutions and petroleum products. 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 the plug sealant for a new service.
