Product Description
Fisher LS200 Series Direct-Operated Regulators
Product Overview

The Fisher LS200 Series Direct-Operated Regulators are engineered for high-capacity, reliable pressure control in natural gas distribution and industrial applications. Designed with a balanced port and optional integral slam-shut, the LS200 ensures precise regulation and safety for furnaces, boilers, burners, and district stations. Its ease of maintenance, requiring only 15 minutes for a disc change, and compatibility with up to 25% hydrogen blending make it a sustainable and future-ready solution. Certified to EN334, EN14382, and DVGW, the LS200 delivers industry-leading performance with minimal environmental impact.

Key Features
  • High-Capacity Design: Balanced port maximizes inlet pressure ratings for superior flow performance.
  • Easy Maintenance: Disc change in under 15 minutes with one-person operation.
  • Integral Slam-Shut: Optional module shuts off gas flow in overpressure or underpressure conditions.
  • Hydrogen Blending Ready: Validated for up to 25% hydrogen service, with testing for 100% compatibility.
  • Fail-Open Design: Ensures safety in district station monitor applications.
  • Bubble-Tight Shutoff: Provides reliable sealing for critical applications.
  • Flexible Configurations: Available in gray iron, ductile iron, and steel with NPT, 125FF, PN16, or 150RF connections.
  • Travel Indicator: Simplifies monitoring of regulator performance (travel monitoring in development).
  • Robust Construction: Operates in temperatures from -40°C to +66°C, with IP66 protection.
  • Certifications: DVGW, V9, CRN, EN334, EN14382, and 25% H2 blending approved.
