Mono-flange: Globe–Globe-Needle / Globe- Needle- Needle / Globe- Needle
DOUBLO: Ball-Ball-Ball / Ball- Needle-Ball / Ball-Needle
Double Block & Bleed Valve (DBB) to replace conventional multiple-valve installations currently in use for interface with pressure measuring systems. By combining customer specified valves into a single forged Block, the number of leak paths is considerably reduced and the mass of the system is lowered reducing the stresses from loading and vibration. As a result of which substantially improves installation and operational safety factors. Reduction in leakage path connections together with a one-piece solution also provides positive installation cost.
Features:
- A one-piece integral forging incorporating up to 3 ball valves or mixture of ball and needle design.
- Strong construction produced from one piece grain flow controlled forged body.
- Various flow and valve configurations available allowing true flexibility to meet all customer requirements.
- Mono-flange more compact than DOUBLO®, adding further space and weight saving possibilities.
- Improved safety leak paths reduced by up to 60%, less susceptibility to vibration
- Installation and component costs reduced by up to 50%
- Weight reduction of up to 65%
- Ergonomically designed operating handles with low torque function.
- Incorporation of standard Flange end connection (ASME B16.5) & Threaded (NPT – ANSI 1.20.1)
- Needle valve technology and state of the art Globe O.S. &Y Design.
