Overview
The Asco 8210G94 is a RedHat series, pilot-operated solenoid valve engineered for general-service fluid control in industrial applications. This 2-way 2-position normally closed solenoid valve features a 1/2 in NPT connection with a brass body. Designed for general fluid control applications, it is constructed with a brass body and NBR seals for efficient operation across a broad pressure range.
Key Features
- Pilot-Operated Design: Utilizes a diaphragm-style internal pilot to manage high flow rates with minimal internal leakage
- Normally Closed (NC): Sealed until the coil is energized to open the valve
- Durable Brass Construction: Brass body with NBR seals provides efficient operation and corrosion resistance
- High Flow Capacity: Features a 5/8 in orifice for reliable flow control
- Multiple Media Support: Suitable for air, water, light oil, non-corrosive fluid, and inert gas service
- Sealed Enclosure Options: Available with NEMA 1, 2, 3, 3S, 4, and 4X enclosure types for diverse environmental conditions
