Series B6400-SE
2-Piece, Standard Port, Bronze
Ball Valves with Safety Exhaust
Sizes: 1⁄4" – 2" (8 – 50mm)
Series B6400-SE 2-Piece, Standard Port, Bronze Ball Valves with Safety
Exhaust feature a drilled valve body and ball to provide vent for relieving
air pressure downstream. The B6400-SE's standard port orifice ensures
minimal pressure drop, while virgin PTFE seats, blowout proof pressure
retaining stem and chrome plated brass ball provide lasting service.
Features
• Valve body and ball are drilled to provide vent for relieving air pressure
downstream. In the closed or “off” position, the B6400-SE provides
continuous air relief on the downstream side of the valve. Ideal for use
where protection of machine tools is critical
• Actuator mounting pads
• Virgin PTFE valve seats are standard
• Pressure rated at 175psi (12 bars)
• Chrome plated brass ball is wiped clean during each operation of the
valve
• Minimal pressure drop due to large ports
• Blowout proof, pressure retaining stem
• Vinyl insulator on heavy duty, zinc-plated, carbon steel handles
• Low operating torque
• Adjustable stem packing gland
• Each valve factory tested
• Valve is unidirectional due to body hole on downstream, with body
flow directional arrow
