Overview

The pressure sustaining relief valve is mainly installed in the drainage bypass, which can ensure that the upstream of the main valve is below the set safety value of the pilot valve. The pressure sustaining relief valve prevents the pipeline and equipment from being damaged by high pressure or sudden high pressure. Sustained pressure relief valves are designed or set to open at a predetermined set pressure to protect equipment such as pressure vessels from being subjected to pressures exceeding their design limit. The pressure sustaining pressure relief valve is mainly installed in the drainage bypass, which can ensure that the upstream of the main valve is below the set safety value of the pilot valve, and prevent the pipeline and equipment from being damaged by high pressure or sudden high pressure.
