Cast Iron Regular Pattern - Standard Type

 
AUDCO Lubricated Taper Plus 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, arc 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 from 1.1/2 are impregnated with a PITK 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


Regular pattern Cast Iron Lubricated Taper Plug Valves arc supplied with square stems suitable for wrench operation (MW series). Valves 4" and above can be offered with Light Duty Gear Units (MO series). Valves 6" and above can be offered with Heavy Duty Worm Gear Unit (MG series). Wrenches and Gear units should he selected as determined by the service conditions, which influence the operating torque. However wrenches should be ordered separately whereas gear units as ordered arc installed on the valves and supplied. Valves can also be offered with Carbon Steel Plug (MWS/MOS/MGS series).
As a standard. Cast Iron 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.
