Cast steel ball valve

Cast steel ball valve

Cast steel ball valve are designed and manufactured to provide maximum service life and dependability. All gate valves are full ported and meet the design requirements of American petroleum Institute Standard API 600 & API 6D,British standard BS 5351 and generally conform to American Society of Mechanical Engineers standard ASME B 16.34. Valves are available in a complete range of body/bonnet materials and trims.

Rang of Materials

Standard body/bonnet materials include nine grades of carbon,low alloy and stainless steels, For special apolications 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 cast steel valves

* Trim changes
* End connection modifications
* Packing and gasket changes
* Operator mounting
* Handwheel extensions
* Pressure equalizing
* AS or FD
* Customer specified coatings
* Weld end bore changes
* Oxygen & chlorine cleaning & packaging
