MOUNTING & SERVICE
- Installation: Valves must be mounted in horizontal pipe with coil vertical, upright and on top. A 40–mesh inline strainer is recommended ahead of the valve. Valve will not open on a Closed System (equalizes pressure across the valve).
- 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.
