Multi Port Cast Iron - Three way & Four way Regular 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 sealing surfaces* Plugs from Vf2** arc 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,

Multiport Lubricated Taper Plug Valves provide

  1. Reduction in number of valves & fillings which results in simplified pipe layout*
  2. Quick and easier operation with increased safetj and reliability.
  3. Reduction in overall cost of installation & operation.
Multiport Plug Valves of three-way (MT Series) and four-way (MU Series) are ideally suited for flow diversion and tight shut-off against full rated pressure in the positive direction i.e. the line pressure holds the plug against the body port which is to be shut off from higher pressure (refer Fig. below).
 
OPERATION  


Multiport Plug Valves arc all supplied wiih square stems suitable for wrench operation. Wrenches, as required, should however be ordered separately.
All Four-way valves arc provided with 90* rotational stops. As a standard. Three-way valves are offered without stops, but on specific request, can be fitted with stops for any combination of flow positions as shown in the Fig, below.

As a standard. Multiport Plug Valves are supplied with AUDCO 731 sealant which is suitable for most services other than acid solutions and petroleum products. On request, plug sealant from a wide range ofTcred, 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.
