Flanged safety valve
DN 65 - 600 | PV 1509 series LDM Armaturen GmbH

The full-lift safety valve with additional loading is a valve designed for automatic protection of a pressure equipment (steam boilers, pressure pipelines, steam-conditioning stations, pressure vessels, turbine extraction etc.) against unpermitted pressure increase over allowable limit.
The valve output guaranteed in accompanying documents is guaranteed only provided that the pressure loss in pipeline does not exceed 3% of opening pressure in inlet pipeline and 25% in outlet pipeline.
The safety valves PV 1509 are designed for water vapour, air, and non-aggressive gases and vapours. The highest temperature of securing medium is up to 600°C. The valves can operate continuously in dust environment with ambient temperature to 80°C. After consulting the producer, it is possible to pipe the valve in environment with ambient temperature below zero. The opening pressure range is specified in the "Technical data" table.
The valves are delivered and must be operated together with their accessories, i.e. control unit and aerating system. Single parts can be delivered only in case of the replacement for previously delivered equipment.
