Fire Safe Ball Valves

 

Fire safe ball valves are designed minimize fugitive emissions and downstream leakage in the event of being exposed to high temperatures characteristic of fires.  Since most ball valves contain non-alloy components for sealing, its their ability to maintain functionality at an elevated temperature or at least fail in a predicable way which differentiates fire safe ball valves apart from other industrial ball valves.

 

When considering fire safe ball valves there are applicable design and testing standards which are typically specified; if there is no project specification for design or test standards, the following are the most common to our product offering.

 

Fire Safe Ball Valve Design Standards

API 608 includes design standards typically applicable to refineries and chemical plants whereas API 6D is applicable to the petroleum and natural gas industries. NACE MR-0175 is a design standard regarding the materials of construction with regards to exposure to hydrogen sulfide which occurs naturally in crude petroleum and natural gas.

 

Fire Safe Ball Valve Testing Standards

API 607 is the primary fire test standard and describes the test parameters as well as the performance evaluation.  API 6D is included as a testing standard as well because it encompasses both design and tst standards, so you might see reference to API 6D under design or testing standards.

 

Our navigation menu lists which valves are considered fire safe, following is a list for easier navigation:

 

Fire Safe One Piece Ball Valves:

 

Fire Safe Two Piece Ball Valves:

 

Fire Safe Three Piece Ball Valves:

 

Control valves can also be rated fire safe:

 

Multiport Fire Safe Ball Valves:

BOTTOM-ENTRY multiport valves are 3-way valves enabling the diversion of flow are also rated fire safe.
