Frese DPRV
Adjustable differential pressure relief valve
Frese DPRV can be installed in domestic and commercial heating and cooling systems.
The valve is an adjustable differential pressure relief valve (DPRV) that ensures the differential pressure across the load or circuit is not exceeded, and a minimum flow through the circuit will be maintained when the control valves are closing down.
Benefits
- Tamper proof pre-setting
- Prevents rising differential pressure in the circuit
- Ensures a minimum flow through the circuit when the control valves are closing
- Differential pressure can be set and adjusted on site
- Pre-setting is simple using the graphs shown in the data sheet
- Reduces noise problems caused by high differential pressure
Features
- Pressure class PN25
- Size DN15-DN32
- Setting range 10 kPa - 60 kPa
- Thread ISO 228
- Differential pressure operating range up to 600 kPa
- Isolation up to 600 kPa
