What is a Fire Safe Ball Valve?
Overview of Fire Safe Ball Valves
Fire Safe Ball Valves are custom-made quarter turn valves that ensure continued sealing capabilities in the event of fire as well as following the fire incident. While traditional ball valves depend on soft seats for their sealing properties, the fire-safe valves feature an additional secondary metal-to-metal seating mechanism, which keeps leakage at minimum even if the soft seats are damaged by high temperatures.
What Makes a Fire Safe Ball Valve Function?
Under normal circumstances, the valve makes use of custom-made soft seats like PTFE or reinforced PTFE to achieve bubble-tight shut-off and easy turn operations.
In case of fire exposure, the seats are likely to be compromised due to high temperatures. At this point, the valve switches to specially made secondary metal-to-metal seats that continue with emergency sealing. The graphite stem packing and body seats also aid sealing at high temperatures.
Key Features
Fire Safe Certified Design
Our Fire Tested Ball Valve range is manufactured and tested as per international fire safety standards like API 607 along with other relevant specifications to ensure reliable performance.
Secondary Metal Seat Sealing
The highly engineered metal back up seat ensures sealing ability in case the main soft seat gets damaged due to exposure to fire, thus reducing the leakage risk until the maintenance can take place.
Bubble Tight Shut-Off
Under normal operating conditions, the soft seating system ensures bubble tight shut-off of liquid, gas and process media while maintaining easy operation of the valve.
Blow-Out Proof Stem
Internally retained blow out proof stem ensures safe operation of the valve in service by preventing stem blow-out in any case.

Materials of Construction
Body Materials
To meet different industrial needs, we offer our fire safe ball valves in several body materials as follows:
- Stainless Steel 304
- Stainless Steel 316
- Carbon Steel (WCB)
- Duplex Stainless Steel
These material choices give the valve the ability to operate effectively under different pressure levels and temperatures.
Seat Materials
The choice of seating material depends entirely on the operating conditions.
Some of the common seat materials are:
- PTFE
- Reinforced PTFE (RPTFE)
- Metal Backup Seat
The combination of soft seat and metal seat gives the valve an excellent sealing capability during normal operations and fire emergencies.
Seal Materials
Sealing effectiveness is attained through the use of advanced materials including:
- Graphite
- PTFE
Graphite seals are especially important for fire safe valves due to their ability to function in high temperatures.
Fire Safe Design Features
Secondary Metal to Metal Seal
In case of high temperatures, the metallic backup seat works to provide an emergency seal in cases where the main soft seat fails, thus minimizing the leakage of fluids in case of fires.
Graphite Stem Packing
The graphite stem packing ensures that there is effective sealing around the stem at high temperatures and helps minimize the likelihood of leaking in case of fire.
Blow-Out Proof Stem Design
Internally held stem protects the operator from accidents in case of pressurized or extreme operating conditions.
Anti-Static Feature
The anti-static feature ensures that any static electricity build up during the operation of the valve is dissipated safely and prevents ignitions in such circumstances.
Working Principle
During Fire Exposure
In case of exposure to fire, the soft seats can wear off because of extremely high temperatures. In this case, metal seating surfaces will work together to provide an emergency seal, while graphite packing will ensure minimisation of stem leakage.
After Fire Exposure
Despite the need for maintenance and inspection after exposure to fire, the valve will keep its strength and provide leak minimisation until isolation of the system will be possible.
Applications & Industries
Petrochemical Plants
Fire safe valves are applied in petrochemical plants during processing of flammable hydrocarbons and processed chemicals.
Chemical Processing
Fire safe ball valves are used in chemical plants dealing with hazardous, flammable or reactive fluids for improved safety and reduced risk of potential fire hazards.
Refineries
Petroleum refineries deploy fire safe ball valves in process isolation, storage and hydrocarbons transfer operations, which demand emergency shut off capability.
Liquefied and Natural Gas
Fire Resistant Ball Valve solutions are deployed in LNG and natural gas processing plants, which demand reliable operation in hazardous environments consisting of flammable gases.
Pipeline System
Critical pipeline systems deploy fire safe ball valves for reliable isolation, shut-down operations and high pressure fluid transport applications.
