Breakdown of Part Number
The model code can be interpreted from the BelGAS P627 part matrix:
P627-082500N6111
- P627 = BelGAS 627 Series pressure regulator
- 08 = 1″ port/body size
- 250 = 140–250 PSIG spring range
- N = NACE construction
- 6 = 3/8″ orifice
- 1 = Steel body / steel case configuration
- 1 = Nitrile seat/material configuration
The official P627 part matrix confirms the 08 = 1″, 250 = 140–250 PSIG, N = NACE, and 6 = 3/8″ orifice designations.
Pressure Range
The specified 140–250 PSIG range means the regulator’s spring is designed to control the outlet pressure within approximately:
140–250 PSIG = 9.7–17.2 bar
The BelGAS documentation lists the 140–250 PSIG range as one of the standard P627 spring ranges.
3/8″ Orifice
The 3/8″ (9.5 mm) orifice provides a relatively large flow passage compared with the smaller P627 orifices. The P627 series offers 3/32″, 1/8″, 3/16″, 1/4″, 3/8″, and 1/2″ orifices, allowing the regulator to be selected according to required flow capacity.
For the 1″ P627 body, the manufacturer’s published flow data gives the 3/8″ orifice a wide-open Cv of approximately 3.42 in the referenced configuration. Actual operating capacity depends on inlet pressure, outlet pressure, gas specific gravity, temperature, and allowable droop
