Pressure holding valves are designed specifically for integration between the pump head of a R032 / R033 dosing pump and the pressure line. They form a compact unit with the pump head and the fluid fittings.
The maximum application-related back pressure for the dosing pump is limited by a manually adjustable, spring-loaded spindle.
R032 / 033-DHV are screwed directly on the pump head and reduce the installation and mounting costs with their specific design.
In addition, the DHV can be integrated in heatable pump head versions.
The pressure holding valves are available in 2 sizes for all R032 / R033 dosing pumps.
Full-PTFE pressure holding valves are also available with two PTFE fittings for integration into a fluid line.
