1. Floating or trunnion mounted ball valves in main bore, each valve is bi-directional and designed for full differential pressure at ambient and low temperature. For main bore valve general features see the ball valve sections (floating ball or trunnion ball).
2. Full die forged structure for all pressure containing parts.
3. Integral body comprising of two ball valves through main bore with a needle bleed valve from the cavity between the two ball valves. Housing design can be split body or end entry (end entry cannot be feasible for all range).
4. Standard primary gasket design is Lip-Seal type, secondary emergency seal always provided for fire-safe purpose.
5. High quality sealing products and reduced leakage points.
6. Improved safety in operations, space and weight.
Didtek manufactures Double Block and Bleed Ball Valve in an extensive range of designs, materials, sizes, pressure classes and end connections that are designed in accordance to ASME B16.34 and where applicable API 6D or BS EN ISO 17292. The valves are fire-safe test approved and include design features to ensure electrical continuity between ball, stem and body.
