Pressure relief valves

Overview

Nominal size DN::
65 - 100
Material sealing element (in contact with medium):
EPDM | FPM
Material diaphragm:
PTFE (EPDM)
Connection:
Socket | Spigot | Flange
  • EPDM diaphragm with PTFE coating
  • most powerful thermoplastic pressure relief valve for large nominal diameters
  • two optional pressure set ranges per nominal diameter, see pictograph
  • for constant working pressures even in systems with counterpressure
  • constant, low vibration control behaviour
  • simple pressure setting possible at any time, also during operation
  • Locks in rest position 100% against back pressure from the valve outlet, suitable for the construction of dosing or injection points
