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