Emergency Shutdown Valves (ESD)

Size Range

From ½ inch to 60 inches Custom or larger sizes available upon request.

Fast Response for
Critical Safety

Purpose:

Emergency Shutdown Valves (ESDVs), also referred to as ESD, ESV, or SDV, are designed to immediately isolate pressure and flow during abnormal or hazardous conditions. These valves are essential safety components, activated to protect equipment, personnel, and processes during overpressure, fire, or other emergency events.

Applications

ESD valves are integral to plant safety systems across a variety of sectors:

  • Oil & Gas – Exploration, Production & Transmission
  • LNG Processing
  • Petrochemical Facilities
  • Refineries
  • Power Plants
  • Desalination and Water Treatment Plants
End Connections

• ASME B16.5 (Flat Face, Raised Face, Ring Type Joint, Threaded)
• ASME B16.47 Series A & B
• MSS SP-44
• ASME B16.25 (Butt Weld, Socket Weld, Weld End)

Material Options

  • Carbon Steel
  • Stainless Steel (including Duplex Stainless)
  • Nickel Alloys
  • Titanium Alloys

Each material is selected to withstand extreme operating conditions and align with plant safety specifications.

Pressure Class Range

ANSI Class 150 through Class 4500

Technical Features & Operation

  • Pneumatically or hydraulically actuated for fast, reliable closure
  • Available in SIL-compliant configurations for functional safety
  • Compliant with ANSI, API, and DIN standards depending on application
  • Can be installed upstream, midstream, or downstream based on system design
  • Designed to integrate seamlessly into control and automation systems
Engineered for Plant Protection

When every second matters, ESD valves provide peace of mind by delivering fast, fail-safe performance -ensuring isolation when it’s needed most.
