            • Check valve

              Design
               

              BLT cast steel check valve are designed and manufactured to provide maximum service life and dependability. All check valves are meet the design requirements of American Petroleum Institute Standard API 600 & API 6D, BS EN 13709 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.

               

              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 steell. 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.
