Technology

BBS Pressure-Lock technology

Exclusively featured on the BBS 11-15 In-Line Manifold Valve

■ Two-piece valve stem design provides easier handle turn operation

■ Needle-tip safety back seating ensures operator safety during process blowout events

Enhanced reliability

■ Process-isolated stem threads increase overall valve life

Simplified operation

■ A. Removable handles - allows for a quick way of adding security and reducing tampering.

■ B. Packing nut - allows for smooth adjustment of stem packing.

■ C. Nut for stem tightness.

■ D. Two-piece stem design with non-rotating tip - provides smooth ergonomic operation, reduces potential leak paths, and decreases overall wear, extending valve life.

Increased operator safety

■ E. Safety back seating - provides integral blowout protection.

Enhanced reliability

■ F. Stem threads isolated from process fluid – increase equipment life and operator safety.

■ G. Modular packing – located below stem threads to isolate thread from process fluid, preventing corrosion.

■ H. Bonnet threads isolated from process fluid – improves corrosion resistance and equipment life with metal-to metal, bonnet-to-body seal.

■ I. One-piece needle tip stem – ensure seal integrity over wide range of pressures and temperatures.
