Description

Fisher LS200 Series Regulators

🔹 Product Overview

The Fisher LS200 Series Pilot-Operated Regulators are designed for medium to high-capacity gas distribution systems where pressure stability, fast response, and safety reliability are critical.

Unlike direct-operated regulators, the LS200 uses a pilot-operated control structure, allowing it to maintain high outlet pressure accuracy even under fluctuating inlet pressure and variable flow conditions.

This makes the LS200 especially suitable for:

✔ Distribution stations

✔ Industrial gas supply networks

✔ LPG and natural gas systems

✔ Commercial gas metering skids

For operators who require consistent downstream pressure and long-term operational stability, the LS200 provides a dependable solution.

🔹 Key Features

✔ Pilot-Operated Control Design

Ensures high pressure accuracy and rapid response to load changes.

✔ Wide Spring Range Options

Supports flexible pressure adjustment for multiple system requirements.

✔ Multi-Material Construction

Available in aluminum, carbon steel, and stainless steel for different environments.

✔ High Emergency Pressure Resistance

Designed to withstand abnormal pressure surges without damaging internal components.

✔ Suitable for Natural Gas & LPG

Adapted for both urban gas and industrial LPG applications.

✔ Stable Performance Under Variable Flow

Minimizes pressure fluctuation during peak consumption periods.

🔹 Application Scenarios

In gas distribution and industrial systems, buyers often face:

❌ Pressure drop during peak demand

❌ Unstable downstream pressure affecting equipment

❌ Frequent recalibration requirements

❌ Risk of system shutdown due to regulator failure

The LS200 series is widely applied in:

✔ City gas pressure regulating stations

✔ Industrial boiler gas supply systems

✔ LPG vapor distribution systems

✔ Commercial building gas networks

✔ Metering and control skids

From a system operator’s perspective:

👉 Stable pressure = stable equipment operation

👉 Accurate regulation = reduced maintenance

👉 Pilot control = long-term reliability

For B-end customers, this means:

Lower downtime, fewer complaints, and safer system operation.
