  Product features to our customer benefit
 
 
•
 Valves meet API 600/ ISO 10434 Design requirements
•
 Body full bore to API 600 / ISO 10434 ensures streamlined flow hence no pressure drop.
•
 Body guided wedge ensures positive seating and eliminates side thrust
•
 Stem wedge connection meets API 600 pull test requirements.
•
 Harder seats (ST6 HF) minimises on line erosion (KSB recommends harder seats)
•
 Differential hardness between seat & wedge maintained to eliminate galling.
   
 
 
Flow Seal
•
 Stellited body seats (KSB recommends harder seats)
•
 Seat rings - seal welded to body
•
 Lapped seat and wedge faces for leak tightness
•
 Streamlined flow path hence no pressure drop
Wedge Design
•
 Flexible wedge ensures perfect seating
•
 Wedging action ensures leak tightness
•
 Leak tightness at low and high differential pressure
   
  'T' head stem wedge connection
•
 Low, centre stem to wedge contact reduces the operating torque
   
 
Body Seal
Bolted Bonnet
 
•
 Encapsulated Gasket with Controlled Compression ensures leak proof joint and prevents unwinding of SS strips
•
 #150 valve with oval / rectangular bonnet has flat gasket
   
 
Gland Seal
 
•
 Die moulded graphite rings ensures effective stem sealing
•
 Top & bottom rings are braided graphite offer smooth wiping action & prevents Graphite depletion
•
 Burnished stem and smooth stuffing box surfaces improve gland sealing life
•
 Two piece self aligning gland arrangement
•
 Hardened back seat for maximum service life
