Description

Fisher Types BLE and BLX Throttle Valve

🔹 Product Overview

The Fisher Types BLE and BLX Throttle Valves are engineered for high-pressure pipeline flow control in demanding gas transmission and distribution systems.

Unlike standard control valves, this series is built for:

✔ Severe pressure environments up to 100 bar (1450 psig)

✔ Stable throttling performance under fluctuating pipeline demand

✔ Robust mechanical strength for long-term heavy-duty operation

Type BLE provides reliable throttling control, while BLX integrates a shutoff valve, offering both flow modulation and isolation safety within a single assembly.

This makes the BLX especially valuable in pipeline stations where space, safety, and reliability must coexist.

🔹 Key Features

✔ High Operating Pressure Capability (Up to 100 bar)

Designed for transmission-level systems, not light-duty distribution.

✔ Two Configurations: BLE & BLX

BLE: Dedicated throttling valve

BLX: Throttle + Integrated Shutoff for enhanced safety

✔ Multiple Body Materials (LCC / WCC-20)

Adaptable to varying temperature and environmental conditions.

✔ Wide Size Range (DN 25 / 50 / 80 | NPS 1 / 2 / 3)

Suitable for station-level installations.

✔ Multiple Pressure Ratings (PN100 / CL600)

Compatible with high-class pipeline standards.

✔ Low Temperature Capability (Down to -30°C)

Reliable in colder operating environments.

🔹 Application Scenarios

In gas transmission or pressure reduction stations, engineers often face:

❌ Pressure spikes during peak demand

❌ Inconsistent throttling under variable flow

❌ Space constraints for separate shutoff devices

❌ Downtime risk during maintenance

The BLE & BLX series is commonly used in:

✔ Gas transmission stations

✔ City gate stations

✔ Pressure reduction stations

✔ Industrial high-pressure gas networks

✔ Pipeline metering skids

From an operator’s perspective:

👉 BLE ensures stable and durable throttling performance

👉 BLX provides flow control and isolation in one body

👉 Reduced installation complexity

👉 Improved operational safety

For B-end customers, this means:

Fewer components. Lower installation cost. Higher system reliability.
