PTFE butterfly valves have historically received bad press due to the perception that they leak. However, with advances in technology and design, manufacturers are now supplying high-quality valves that are bubble tight.
Bundor is offering PTFE lined butterfly valves with a liner that has a stable design. The operational surfaces of the shaft sealing is mechanically machined to ensure proper and accurate fit. With lack of memory in PTFE, this is critical on high cycling valves.
The matched and machined sealing surfaces ensure 360-degree sealing. Kv values, as well as opening and closing torques, are optimised.
Bundor confirms that the aforementioned features will ensure long service life of PTFE butterfly valves.
