- Maintenance: As with any piece of equipment, reasonable inspection and maintenance of components should be periodically performed. Frequently check operation, cleanliness and internal wear. Any questions, consult factory.
NOTE: Gould Solenoid Valves are designed for Industrial–Commercial applications. Residential/Consumer applications will void the warranty. Questions ~ Call our Experts.
