Unlike a safety valve with a possibility of failure, the Rupture Disk does not malfunction and reliably releases the pressure at the set pressure. Therefore, there is no pre-leakage.However, the Rupture Disk is fully opened once it ruptures at the set pressure and remains open until the fluid is exhausted (no blow stop). After the safety valve opens at the set pressure, the valve closes and fluid discharge stops (blow stop) when the pressure falls below the set pressure.

Depending on the model, this product has a production record of up to 1,000A.For details, the person in charge or "Inquiry Form" Please contact us.

For your safety, we recommend replacing discs every year even though the discs are not ruptured.
