PP Pressure relief valve
For a customer in the field of dosing technology, we have developed a system with pumps and valves for the dosing technology. An integral part of this system are pressure-retaining valves from ASV Stübbe, which are ideal for this purpose. Pressure relief valve a number of advantages in:
Operation
- chemical plant construction
- industrial plant construction
- Water Treatment
- electroplating
Application
- Directly controlled by the medium, the pressure-maintaining valve in process engineering plants serves to keep the preset working pressures on the primary side constant.
- To avoid pressure peaks, the pressure relief valve can also be used as an overflow valve. For this purpose, the pressure-maintaining valve is mounted in a bypass line.
- Pressure relief valves are not safety valves in the sense of the Pressure Equipment Directive.
valve function
- Closed at rest, the diaphragm under the valve seat is acted upon only by the low secondary pressure. If the working or primary pressure increases, the diaphragm is raised against the spring force. The valve opens, there is a pressure reduction.
Valve Position
- easily adjustable over the entire pressure range
- Safely by Verplomben against unauthorized adjustment
Flow medium
- Neutral and aggressive liquid media containing components containing solids, as long as the wetted parts of the valve are stable at the operating temperature according to the ASV resistance list
