  1. The parts of the flow path are made of a material resistant to corrosion, which excludes the presence of rusty debris.
  2. Low noise level.
  3. The pressure balanced design of the valve allows the reduced pressure to be kept constant without being influenced by the inlet pressure.
  4. The closed design keeps liquid inside even if the diaphragm is damaged or broken.
  5. The valve top is easily removable for inspection and maintenance.
  6. Compact and lightweight design makes piping easy.
