controller primarily for use in district heating
The controller is normally closed and
opens on rising differential pressure.
- Bypass valve are to be selected on the required bypass flow rate and opening pressure loss
- The valves shall be capable of the required opening pressure within the published spring range
- The valves shall be installed with a partner valve to enable bypass flow measurement and flow limiting if necessary
- The partner valves shall be fixed orifice in DN15-50 and variable orifice in DN50 (high flow) to DN400
