Notes:
- External pilot regulator required only when supply pressure (primary) to the valve is below the
minimum operating pressure of the 48 series valve.
- When an internal pilot regulator is used with the 48 series valve, the valve should be ordered
as external pilot and the base should be ordered as internal pilot. This ensures that the pilot
supply is not regulated. If an internal pilot valve and base are used with an internal pilot
regulator, the pilot supply is regulated.
Example: Valve 48B-AM D -AA A -GxxP-xxx with PR48B-AAAA
