High Accuracy Pressure Reducing Valve Pilot Operated Universal Regulator

Pilot-operated universal regulator 2334 - DIN DN 65 to DN 400 valve size and PN 16 to PN 40 pressure rating

The universal regulators consist of a large globe valve acting as the main valve and a maximum of three smaller pilot valves connected in parallel in a bypass line. The pressure drop across the regulator is used to operate the valve, whereby the Venturi nozzle in the bypass line amplifies the pressure drop as the flow rate increases. The pilot valves open depending on the controlled variable used to operate them. As a result, a flow rate arises in the bypass line over the Venturi nozzle, which is used to control the main valve (open or close it). This allows the controlled variable (pressure, differential pressure, flow rate or temperature) to be controlled. Electric signals from an electric actuator can also be used to operate the valve and takes influence on the control loop, too.

Special features • Single-seated globe valve with flanged end connections

• Suitable for district heating plants in accordance with DIN 4747-1 (requirements stipulated by AGFW (German District Heating Association) concerning components in house substations)

• Wide control range and high useable rangeability at low pressure loss

• Pilot operated by the medium, with a maximum of three pilot valves

• Excellent stability and control accuracy even when the pressures fluctuate considerably

• Smooth opening and closing of the main valve

• Wide set point range and convenient set point adjustment at the pilot valve

• Numerous control functions and the possibility to combine several functions
