Low temperature Butterfly Valve

FEATURES

• Simple structure: The low-temperature butterfly valve consists of a valve body, valve seat, valve stem, valve disc, etc. It has a simple structure, is easy to maintain and replace, and reduces production and usage costs.
• Small size: The low-temperature butterfly valve adopts an elastic sealing structure, which occupies a small space and is convenient for installation and maintenance.
• Lightweight: Low temperature butterfly valves have a small volume and light weight, which can reduce the quality of pipeline systems and lower construction costs.
• Good sealing performance: The low-temperature butterfly valve adopts an elastic sealing structure, which can effectively prevent medium leakage and ensure the safe operation of the system.
• Corrosion resistance: The valve body and disc materials are generally made of stainless steel, carbon steel, titanium alloy, etc. which can resist the corrosion of corrosive media such as sulfides and saltwater.
