|Compound||JIS Rc Threaded Connection|
A filter (40 mesh) is installed on models from 20A to 50A.
Pressure gauge connection with JIS Rc 1/4 thread.
Variants available with fluoroelastomer components.
- 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.

Noise performance graph
This graph shows the change in reduced pressure when the pressure of 0.6 MPa at the valve inlet begins to fluctuate between 0.15 MPa and 1.0 MPa, while the reduced pressure is set at 0.1 MPa.
