The Asco 8263G304 Solenoid Valve is a direct-acting, normally closed 2-way valve built for hot water and steam systems requiring zero pressure differential. With EPDM seals and a brass body, it handles elevated temperatures in tight-loop thermal processes. Its compact 0.36 Cv makes it effective in high-cycle heating applications such as laundries and autoclaves.

Installation and Operational Notes
- Verify that 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.
