Fire-safe Valves

Frigate’s certified fire-safe valves are engineered to maintain absolute thermal containment and positive shut-off seal integrity even under catastrophic thermal exposure. Designed to meet stringent international fire test standards, these valves mitigate hazardous process leaks and safeguard your critical industrial infrastructure during emergency thermal events.

*Listed timeframes are indicative ranges based on standard current capacities. Actual delivery schedules depend on material availability, alloy specifications, and exact engineering parameters submitted during final RFQ validation.

Product Description

Frigate’s fire-safe valves feature a dual-seal design incorporating a resilient soft seat for bubble-tight operational performance under normal conditions, paired with a precision-machined secondary metal seat. In a fire event where soft elements decompose, the line pressure forces the closure element against the metal backup seat to block media escalation downstream.

Seat Configurations

Primary Soft Seat (PTFE/RTFE/Devlon) with Secondary Metal-to-Metal Fire Seal

Stem Seal Design

Anti-Blowout Stem with Live-Loaded Graphite Packing Rings

End Connections

Flanged (RF, RTJ), Butt-Weld (BW), Socket-Weld (SW), Threaded (NPT)

Operating Temperature

$-50^\circ\text{C}$ to $+400^\circ\text{C}$ (Dependent on shell and seat material matrices)

Leakage Class

API 598 (Zero Leakage), ISO 5208 Rate A (Soft Seated)

Fugitive Emissions

ISO 15848-1 Class AH / CO3, API 622 Certified Packing

Wall Thickness

Compliant with ASME B16.34 requirements

Face-to-Face Dimensions

Compliant with ASME B16.10 standards

Actuation Options

Manual Lever, Worm Gear, Pneumatic, Electric, or Hydraulic Actuators

Quality Testing

100% Hydrostatic, Pneumatic, and Fire-Safe Prototype Tested

Technical Advantages

Our fire-safe valve architecture employs live-loaded graphite stem packing and robust metal-to-metal seating boundaries to effectively eliminate external fugitive emissions and internal seat leakage during thermal duress. The anti-blowout stem design guarantees structural integrity and operational safety under maximum localized system pressures, even if the primary seals melt away entirely.

Industry Applications

Oil & Gas Refineries

Crucial for isolating highly volatile hydrocarbons and flammable feedstocks in cracking, distillation, and high-pressure separation units during thermal emergencies.

Petrochemical Processing

Deployed in ethylene, aromatics, and polymer production pipelines to halt product propagation and secure storage terminal lines if localized fires breakout.

LNG Terminals & Cryogenics

Ensures immediate thermal containment during transfers at regasification plants, storage facilities, and bunkering stations handling marine liquefied natural gases.

Offshore Platforms & FPSOs

Saves lives and topside infrastructure by sealing off subsea tie-backs, production manifolds, and extraction lines from extreme hydrocarbon fire hazards.

Power Generation Facilities

Manages fuel gas supply lines, turbine lubrication systems, and chemical treatment loops requiring absolute isolation fail-safes during plant thermal failures.

Industrial Chemical Storage

Installed on bulk tank farms, loading docks, and transfer manifolds handling hazardous solvents, alcohols, and combustible chemical feedstocks.

Having Doubts? Our FAQ

How do we submit our custom datasheet and DFM requirements for a formal engineering review?

You can upload your proprietary datasheets, piping schematics, and custom engineering specifications directly through our secure RFQ portal. Frigate’s specialized B2B technical team reviews every line item—including custom alloy mandates, unique face-to-face dimensions, and actuation requirements—to ensure absolute compliance before providing a formal commercial proposal.

Can Frigate manufacture custom fire-safe valves that deviate from standard ASME B16.10 dimensions for retrofit projects?

Yes, we frequently build custom drop-in replacements for brownfield modifications. If your existing piping layout restricts you to non-standard face-to-face lengths or specialized flange drillings, our engineering team can modify the body casting and machining programs to match your exact footprint without compromising API 607 fire-safe compliance.

What level of material traceability and NDT documentation do you provide with custom alloy orders?

We maintain 100% material traceability throughout our supply chain. Every custom order is delivered with comprehensive EN 10204 3.1 certification, MTRs (Material Test Reports), and requested NDT (Non-Destructive Testing) reports such as Radiographic (RT), Magnetic Particle (MT), or Positive Material Identification (PMI) for high-alloy components.

If our project requires a specific brand of actuator or positioner, can you source and integrate it?

Absolutely. While we offer standard actuation packages, we regularly integrate client-specified components (such as specific pneumatic cylinders, smart positioners, or limit switches from approved vendor lists). We handle the mechanical mounting, alignment, and full functional testing of the complete automated assembly at our facility before dispatch.

We require third-party witness inspection (TPI) before shipping; how does Frigate facilitate this?

We routinely coordinate with major international inspection agencies as mandated by your project quality plan. Once production reaches the designated hold points, our QA/QC team provides your appointed inspector full access to our testing bays for witness pressure testing, fire-safe prototype reviews, and final dimensional verification.
