- Pressure Range: 20-1000 psi
- For optimal valve operation, specify your actual pressure range. A minimum pressure drop of 10 psi (ΔP) is needed for proper operation.
Select the Maximum Pressure Rating closest to but not exceeding the actual pressure
under which the valve will operate (Example: offered ranges are 5-150 psi or 10-300 psi.
Your corrosive application has a Maximum Pressure of 110 psi > pick the 5-150 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.
- 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.
