1 High Pressure Valves Series Angle Valves Series Angle Valves Description High pressure angle valves with split body. Connections manufactured to IG standards. Other high pressure screwed connections or fl anges are possible. These valves provide a basis for high pressure relief special designs e.g. with wear bushes, dissipator sleeves, additional aperature plates. Furthermore, due to their unique construction, they can be manufactured from almost any desired material.
