Dimensional drawing
Overview
The small spacing between pipes and the space-saving feature make it suitable for use in pipe systems, meeting customer demands. Its use of a separated type of PTFE valve seat, with a patented design that includes valve seat pressure compensation functionality, results in excellent shut-off capabilities. This is different from traditional coated butterfly valves, where the rubber ring can become deformed and hardened, leading to increased operating torque and leaks. In addition, the eccentric butterfly valve seat can be replaced to suit the system’s liquid compatibility and can be quickly fitted with insulation materials to meet anti-condensation requirements for ice water systems.
