Overview
The ASCO 8210G035 is a pilot-operated, 2-way solenoid valve from ASCO’s renowned RedHat II series. Engineered for general-purpose fluid control, this 24V DC normally open valve features a 3/4″ FPT (female pipe thread) connection and delivers a flow coefficient (Cv) of 5.5. The valve operates from 0–125 PSI and is manufactured from lead-free brass with resilient seals for minimal internal leakage and long service life.
Key Features
- 24V DC solenoid coil (11.6 W power consumption)
- Normally open (NO) design—opens automatically when de-energized for fail-open safety
- Pilot-operated diaphragm valve with high flow capacity (Cv 5.5)
- Lead-free brass body compliant with ANSI/NSF 372 and Safe Drinking Water Act
- RedHat II watertight enclosure rated NEMA 1, 2, 3, 3S, 4, and 4X
- Resilient Buna-N seals minimize internal leakage and wear
- No minimum operating pressure requirement; can be mounted in any direction
