Floating Ball Valve

 

Design   Ranges of Materials
KATA steel ball valves are designed manufactured to provide maximum service life and dependability. All ball valves are full ported and meet the design requirements of American Petroleum Institute Standard API 608&API 6D British standard BS 5351 and generally conform to American Society of Mechanical engineers standard ASME B16.34 valves are available in a complete range of body/bonnet materials and trims. Standard body/bonnet materials include nine grades of carbon, low alloy and stainless steel, for special applications they can be supplied in other grades of alloy and stainless steel. There's a full range of trim materials to match any service optional packing and gasket materials are available for a full range of service conditions.

 

Available Modifications For KATA Steel Valves    
Trim changes
End connection modifications
Packing and gasket change
Operator mounting
Handwheel extensions
Pressure equalizing
As or fd
Customer specified coatings
Weld end bore changes
Oxygen&chlorine cleaning & packaging

 

A)Operation
Extended lever for easy operation. Also available with gearing, motor actuators, pneumatic or hydraulic actuators for more difficult services
  B)Body & Bonnet
Split or 3-piece,split body& bonnet for 12" & small. Disassembles easily for repair or replacement of internal components.
  C)BORE
Full bore or reduced bore. Full-bore design provides exceptional flow control.
D)End Connections
A choice of flanged RTJ flanged or buttwelding end for piping flexibility.
  E)Packing
Std packing multiple v-teflon packing, combined with live loading,maintains packing compression under high-cycle and severe service applications.
 
F)BPS
Blow-out proof stem, a pressure-safe stem shoulder design that protects against failure under excess pressure.
G)AS
Anti statics. A metallic contact is always granted between ball and stem /body to discharge eventual statics build-up during service.
  H)FS
Fire safe designed to API607 or BS 6755 to grant their operation suitability in case of fire. Secondary metal-to metal seal acts as backup if primary seal is destroyed by fire. Valves ordered for compliance with API 607 will be provided with graphite packingand gaskets.
