- *Note 1) Ensure a differential pressure of at least 0.1 MPa between the signal pressure and the set pressure. If the differential pressure is too small, due to the structure of this product, abrasion may affect the inner compartments and the bleed amount from the exhaust port may increase, which in turn may affect the characteristics of the product.
- *Note 2) Pressure difference between the lock being activated and the lock being released
