- Pressure Range: 5 – 150 OR 10-200psi, Minimum pressure drop of 5 OR 10 psi (ΔP) required for proper operation. For optimal valve operation, specify your actual pressure range.
Select the Maximum Pressure Rating closest to but not exceeding the actual pressure under which the valve will operate (Example: offered ranges are 5-50 psi or 5-125 psi. Your steam application has a Maximum Pressure of 75 psi > pick the 5-125 psi rated valve).

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.
