CRACKING PRESSURE AND RESEALING PRESSURE
van-giam-ap-add1
Cracking pressure: the pressure at which the first indication of flow occurs. The repeatability of the cracking pressure of each valve after initial relief is within ± 5% at room temperature.Resealing pressure: the pressure at which there is no indication of flow. Resealing pressure is always lower than set pressure.Back pressure: the pressure of the outlet of the valve. It increase the set pressure
