ASCO 8290B10 2-Way Normally Closed Solenoid Valve, 1″ NPT, Bronze Body

Description

ASCO 8290B10 2-Way Normally Closed Solenoid Valve Overview

The ASCO 8290B10 is a heavy-duty, 2-way normally closed solenoid valve engineered for demanding HVAC, plumbing, and industrial fluid control applications. Built with an angled bronze body and a durable Teflon seat, this valve delivers reliable shutoff performance across a wide range of media including air, water, and steam. Its pilot-operated design with a 63 mm entry under-disc pilot operator allows efficient actuation at low power while handling high-flow requirements.

Key Features

• 2-way, normally closed (NC) configuration — valve closes when de-energized for fail-safe operation
• 1″ NPT pipe connection for straightforward installation in standard piping systems
• Angled bronze body construction for corrosion resistance and long service life
• Teflon seat provides excellent chemical compatibility and tight shutoff
• 63 mm entry under-disc pilot operator design for efficient, low-power actuation
• High flow capacity with a 19 Cv flow coefficient
• Pilot operating pressure range: 60–150 PSI (air or water)

Why Choose the ASCO 8290B10?

ASCO is a globally recognized leader in solenoid valve technology, and the 8290B10 reflects that legacy of quality. The normally closed design ensures the valve defaults to a closed (safe) position upon loss of power — a critical feature for safety-sensitive HVAC and process systems. The bronze body and Teflon seat combination offers outstanding durability against corrosion and chemical attack, while the high 19 Cv flow coefficient ensures minimal pressure drop across the valve. Whether you’re managing steam, water, or compressed air, the ASCO 8290B10 delivers consistent, dependable performance.
