1. Maximum inlet pressure is equal to set pressure plus maximum differential.
2. Requires special 6300 Series pilot construction without integral check valve and with external Type 1806H 40 psid / 2.8 bar d check valve.
3. Should not exceed the body rating limit. Use this pressure value or the body rating limit, whichever is lower.
