Becker NBV Series

Description:

The NBV Non-Bleed Valve renders the primary control instrumentation non-bleeding when the control valve reaches full-open and full-closed positions. This is ideal for Monitor Regulators and Standby Regulators that typically remain in the full-open or full-closed positions. The NBV features bleed shutoff at both ends of valve travel with no adjustment. The NBV is the primary choice for Non-Bleed technology on Becker double-acting control instrumentation. Note restrictions of usage for the NBV.

• NBV No Bleed Valves minimize atmospheric emissions by eliminating bleed gas when the control valve is in a full open and/or full closed position.
• No adjustment
• Modular design minimizes tubing and fittings
• Only one moving part
• Easy retrofit to all existing Becker double acting instrumentation

NBV No Bleed Valves are compatible with ALL Becker double acting instrumentation:

• VRP Model Pilots
• VRP-B Model Pilots
• HPP-2 Model Positioners
• HPP-2E Model Positioners
• HPP-3 Model Positioners
• HPP-3E Model Positioners

Note that Becker single-acting instrumentation do NOT utilize Non-Bleed Sensors.

NBV No Bleed Valves are typically used when double-acting control valves remain in a full open and/or full closed position such as monitor or standby regulators.

NBV No Bleed Valves are utilized when the following conditions exist:

• 75 psig > P_supply < 150 psig
• P_discharge < 60 psig
