Honeywell VP513A1188 Pneumatic Valve

The Honeywell VP513A1188 pneumatic valve is a reliable normally-open control valve used in pneumatic HVAC systems to modulate flow in response to a controller's branch-line pressure signal. It features a 5/8" flare connection and operates over a 3–7 psi spring range with a 2.5 Cv flow coefficient, making it well suited for terminal-unit and zone control applications.
