-
Precision for Fixed-Factor Billing: The 627F is designed to meet the strict requirements of pressure factor measurement. Its pilot-operated design eliminates the “droop” typically found in spring-loaded regulators, ensuring the downstream pressure remains at the exact setpoint required for accurate billing.
-
External Registration Accuracy: This regulator uses external registration, meaning it senses pressure directly from the downstream piping via a control line. This bypasses any turbulence at the valve outlet, providing a much more accurate pressure signal to the pilot.
-
Wide Range of Flow Capabilities: Despite its focus on precision, the 627F does not sacrifice capacity. It can handle a wide spectrum of flow rates, making it suitable for varying loads in commercial and industrial settings.
-
Easy to Maintain: The 627F features a modular design that allows for the inspection and replacement of the orifice and valve disk without removing the entire body from the line. The pilot is also easily accessible for adjustment or service.
-
Installation Adaptability: The regulator can be installed in various orientations, and the actuator can be rotated to accommodate tight piping configurations or specific site requirements.
-
Tamper-Resistant Design: To protect the integrity of billing systems, the 627F includes a cap over the pilot adjustment screw. This discourages unauthorized changes to the setpoint, ensuring the system remains within its calibrated parameters.
-
Tight Shutoff Capability: Utilizing high-performance soft-seat materials, the 627F provides a bubble-tight seal during zero-flow conditions. This prevents pressure buildup in the downstream system, which is critical for both safety and measurement accuracy.
