The Challenge
At metering and regulating stations, more than 95% of lost and unaccounted‑for gas is caused by venting from pneumatic controllers. Both continuous‑ and intermittent‑bleed designs intentionally release gas to atmosphere during valve actuation, creating a persistent source of methane emissions and product loss that increases compliance risk and erodes saleable gas volumes.
The Solution
Spartan Controls implemented Type FL and EZH Series self‑contained pressure regulators to eliminate atmospheric bleed gas. Unlike traditional pneumatic controllers, these regulators use a self‑contained control system that routes 100% of control gas downstream, rather than venting to atmosphere.
The solution delivers bubble‑tight shutoff, precise pressure control, and long service life in severe operating conditions. Failure‑mode options and easy in‑line maintenance further improved reliability and safety, making the regulators well suited for high‑duty metering and regulating applications.

The Value
The self‑contained regulator solution delivered clear operational and economic benefits:
- Elimination of atmospheric bleed gas, addressing up to 95% of lost and unaccounted‑for gas at regulating stations
- Recovered product value by retaining gas within the downstream system
- Improved ROI through reduced gas loss and lower emissions exposure
- Enhanced operational safety with bubble‑tight shutoff and fail‑safe options
- Improved environmental compliance, supporting methane‑reduction objectives
