The Asco 8263G305 Solenoid Valve is a direct-acting, normally closed 2-way valve built for hot water and steam service requiring zero pressure differential. Its EPDM or PTFE seals withstand high heat and pressure, making it ideal for continuous-duty thermal systems. The compact design helps simplify installation in space-constrained equipment.

Installation and Operational Notes
- Verify the solenoid coil voltage matches the supply before energizing.
- Inspect and clean valve internals regularly to prevent blockage.
- Shut off the fluid supply and depressurize before performing service.
- Mount the solenoid in an upright position for optimal performance.
- Use an upstream strainer or filter to block harmful particulates.
