SUPER-H - Class 150 & 300 - Short & Venturi Patterns

 
AUDCO SUPER-H Pressure Balanced Plus Valves have been developed to reduce the operating torque in plug valves without compromising the in-line maintenance capability. The plug and body seating surfaces, which are lapped and matched, are not exposed to the line fluid while valves are in open condition; this confines inevitable corrosion and erosion to less critical areas. Sealing is further enhanced by specially developed plug sealants charged evenly around the seating surfaces. The plug is impregnated with PTFE based anti-friction agent - 'SUPER LoMif which provides greater wear resistance and ensures consistent operating torque
 
PRESSURE BALANCED PLUG  


In a standard taper plug valve the line fluid finds its way into the large end chamber of the plug. The resultant force pushes the plug into its taper scat causing taper locking and possibly valve seizure. This resultant force persists when the subsequent line pressure remains high or is reduced. To unseal the taper locking and keep the valve operational frequent sealant injection is required.

In pressure balanced plug valves, pressure balancing is achieved by providing two holes in the plug connecting the chambers at each end of the plug. The chambers, one


 
 
Pressure balancing climinates out of balance and consequent taper locking. The Fig.shows clearly how a balanced position iS reached when line pressure is allowed to equalise the pressure acting on each end of the plug.
 
FIRE SAFE
SUPER-H plug valves are designed to meet standards for tire test. The features incorporated in the valve make the valve seal and operate effectively even after being subjected to varying temperatures and duration resembling lire accidents.
 
 
OPERATION AND MAINTENANCE
 
SL-PER-H plug valves generally need very little attention after installation. However for trouble free operation sealant injection as recommended is to he carried out. Please refer to "Installation. Operation & Maintenance manual tor SUPER-H Pressure Balanced Plug valves" for details, por ease of adjustment, it is desirable that 6* (150 mm) clearance be maintained around the pressure screw, located at the bollorn of the valve
.
As a standard, SUPER-H plug valves arc supplied with AUDCO 733 sealant which is suitable for most hydrocarbon services. On request, sealant from a wide range offered, can be supplied to suit the nature of service. It is recommenced that you consult tis before selecting the sealant for a new service

 
 
 
fitted with a non-return valve acts as a balancing mechanism for the plug. The pressure in the large end chamber always equals the line pressure and the pressure in the small end chamber is always equal to or greater than the line pressure, minimising the resultant force.
