Product Introduction：
Split-type PTFE-lined butterfly valve (two-piece split-type PTFE-lined butterfly valve)
The valve body is split in half vertically along the valve stem centerline and fastened together with high-strength bolts.
It is available in two main series: split-type wafer-type PTFE-lined butterfly valves (D71F4/F46, D671F4) and split-type flange-type PTFE-lined butterfly valves (D41F4/F46, D641F4).
All channels are lined with PTFE/F4, FEP/F46, or PFA fluoroplastics. The metal matrix completely isolates it from highly corrosive media, making it a mainstream corrosion-resistant shut-off/regulating valve in the chemical, desulfurization, and electroplating industries.
Advantages of (compared to integrated types):
Perfectly molded lining, eliminating leakage.
Extremely low maintenance costs, parts can be replaced individually.
Stronger valve body rigidity, stable pressure resistance.
Upgraded sealing performance, bidirectional zero leakage.
Suitable for wear-resistant conditions containing particles.
Suitable for automated remote control.
