Our expansion joints protect your equipment from a variety of pressure sources while being low maintenance, durable, and providing maximum efficiency.
TOT Valve manufactures expansion joints for industrial and commercial facilities that use pumping, piping, or ducting and require expansion or movement joints to handle thermal expansion, vibration, or ground movement.
Designed in a variety of materials such as rubber, stainless steel, or polytetrafluoroethylene (PTFE), our premium, high-performance expansion joints ensure safe and reliable operation, support system integrity, reduce fatigue, and reduce maintenance downtime.
All of our expansion joints undergo rigorous testing to ensure they meet international standards such as DIN, ANSI, JIS, and perform reliably in your system. Our OEM and custom expansion joints are widely used in industries such as oil and gas, aerospace, power generation, petrochemical, water supply, and wastewater treatment.
Contact us today and let us help you optimize pipeline efficiency and reduce operational downtime.
Be careful when choosing a new valve supplier, the disappointment of poor quality can last much longer than the joy of a low price!
