ASCO 8262H078 Solenoid Valve

The ASCO 8262H078 is a compact, general‑service solenoid valve engineered for on/off control of compressed air and inert gases in instrumentation, automation, and light process lines. It is a 2‑way, 2‑position valve that is normally closed, delivering reliable shutoff when the coil is de‑energized. The valve body is brass with NBR seals, providing solid durability in typical industrial environments. It features a 1/4 in NPT inlet and a flow orifice of 9/32 in, offering a balanced combination of quick response and precise flow control, with a Cv of 1. The coil operates on 120 VAC (60 Hz) and is specified without a junction box enclosure, simplifying mounting in standard control circuits. Maximum differential pressure for air or inert gas service is 50 psi, making it suitable for low‑to‑moderate pressure lines. This model is part of ASCO’s 8262 family of general‑service valves, designed for dependable, long‑term operation in HVAC, instrumentation panels, and compact pneumatic systems. In installation, energizing the coil opens the valve to allow flow, while de‑energizing it returns to the closed position, ensuring straightforward integration with conventional relays or solid‑state controllers. The 8262H078 combines brass construction, a compact 1/4" porting footprint, and a robust 120 VAC coil to deliver a reliable, low‑maintenance solution for precise gas and air control at modest pressures.
