This is precision, pilot-operated regulator, capable of a wide range of stable pressure settings. The built-in check valve permits secondary pressure to be fed back to the primary side if the primary pressure supply is shut off.

The nozzle flapper high-sensitivity pilot amplification system has achieved adjustable sensitivity of 0.001MPa. Large relief flow enables strong resistance against excessive pressure at secondary side and prevents reverse flow. This is regulator is suitable for balancer and tension control.
