The Prevent Freeze & Crystallization Breather Valve is specifically engineered to eliminate these risks. Whether you are dealing with sub-zero temperatures that cause ice buildup on valve seats or medium vapors (like bitumen or sulfur) that crystallize at ambient temperatures, this valve ensures your storage tank maintains its structural integrity through consistent, unobstructed breathing.
Producdt Description:
We designed the Prevent Freeze & Crystallization Breather Valve specifically to eliminate the operational risks that come with extreme temperatures. Whether your facility faces sub-zero winters that cause ice buildup on valve seats, or you’re managing medium vapors like bitumen or sulfur that crystallize the moment they hit ambient air, this breather valve is built to handle it.
By preventing internal blockages, this specialized breather valve ensures your storage tank maintains its structural integrity through consistent, unobstructed breathing. It’s not just about venting; it’s about providing a reliable breather valve solution that stays functional when standard equipment fails, giving you peace of mind in the most brutal climates.

Q1:How does the valve prevent ice buildup on seats?
A1:It utilizes internal vapor heat transfer or an external heating jacket to keep the breather valve components above the freezing point, ensuring the pallet never “sticks” to the seat.
Q2:Can this handle vapors like sulfur or bitumen?
A2:Yes. For media that crystallize at ambient temperatures, we recommend our crystallization breather valve with a steam jacket to keep the product in a gaseous or liquid state.
Q3:What materials are used for low-temp service?
A3:We use specialized low-temperature carbon steel or 316L stainless steel combined with cryo-grade PTFE seals to ensure the breather valve remains ductile and functional at -60°C.
Q4:Is electric heat tracing an option?
A4: Absolutely. We can equip the Prevent Freeze & Crystallization Breather Valve with explosion-proof electric heat tracing for facilities where steam or thermal oil is unavailable.
Q5:Does it require special installation?
A5:While installation is similar to standard valves, ensure the heating medium (if applicable) is correctly connected to the jacket to maintain its anti-freeze properties.
