Open pressure deviation
Opening pressure error

When the set pressure is greater than or equal to 0.5 MPa, the allowable deviation is 3% of the set pressure. When the set pressure is less than 0.5 MPa, the allowable deviation is ± 0.014 MPa.

When the set pressure is 0.5MPa or above, the allowable deviation is 3% of the set pressure. When the set pressure is less than 0.5MPa, the allowable deviation is ±0.014MPa.
