Control Accessories - General Pressure Reducing (PR): The valve will regulate to maintain a set downstream pressure, regardless of upstream pressure or flow variations. Should the downstream pressure fall below the requested value, the valve will open fully. Pressure Sustaining (PS): The valve will maintain a steady, predetermined pressure in the network, upstream of its location. If the pressure falls below the set-pressure, the valve closes drip tight. 3-way Pilot Valves: Ports Marking: S - Pressure sensing port P - Port for connection of upstream pressure. C - Command port, connected to the valve control chamber. V - Vent port. Through this port water are vented when the valve opens. Operating Principle: CLOSE - Connects ports P to C thus letting the upstream pressure into the valve bonnet. OPEN - Connects ports C to V thus venting the pressure in the valve bonnet. LOCK - Keep the valve in the present position by blocking all ports.
66
2-way Pilot Valves: Operating Principle: Increases or decreases a drainage passage from the valve control chamber to downstream. The inlet to the chamber is via a fixed orifice or a regulated needle valve. CLOSE - The drainage flow through the pilot is smaller than the inlet flow. OPEN - The drainage flow through the pilot is larger than the inlet flow. LOCK - The drainage flow through the pilot is equal to the inlet flow.
3-way Manual Selector Valve: A ball valve with one common (fixed) port and three functional ports: “CLOSE” - Connected to the upstream. “OPEN” - Vented to the atmosphere. “AUTO” - Connected to the command port of the control device (pilot, solenoid etc.).
Needle Valve / Orifice: For flow limitation in the control system and reduction of the response speed of the main valve.
Shuttle Valve: Tee shaped pressure selector selecting the higher pressure when the valve is controlled by two pressure sources. 67

Hydraulic Equations Headloss Calculation
Q=gpm Cv - taken from the technical publications Result given in PSI
Q=m3 /h Kv - taken from the technical publications Result given in Bar
Headloss Calculation Using K (Dimensionless)
v=f/s g=32.17f/s2 Result given in PSI
v=m/s g=9.8m/s2 Result given in mwc
Relief Valve Sizing
Q=gpm - Relief flow (designed flow at set relief pressure) P=psi - Required set pressure Result given in inches
Q=m3 /h - Relief flow (designed flow at set relief pressure) P=mwc - Required set pressure Result given in mm
Cavitation Calculation
P=psi For Dorot 300 Series σc ≥1.45 is safe For Dorot 100 & 500 Series σc ≥ 1.55 is safe
P=mwc For Dorot 300 Series σc ≥ 1.45 is safe For Dorot 100 & 500 Series σc ≥ 1.55 is safe
