HIGH-CAPACITY Regulators
FEATURES:
• Inline mounting
• Piston-type design
• Self-relieving; optional non-relieving
• Pressure gauge
• Pressure adjustment locking key
Reverse-flow regulators provide regulated in-to-out pressure control, plus
quick exhausting from out-to-in. Used for applications, such as weld guns,
requiring quick exhausting through the regulator. Piston type design.
