Purpose:

Defines all control valve links contained in the network.

Format:

One line for each valve containing:

- ID label
- ID of start node
- ID of end node
- Diameter, inches (mm)
- Valve type
- Valve setting
- Minor loss coefficient

Remarks:

1. Valve types and settings include:

   Valve Type | Setting
   --- | ---
   PRV (pressure reducing valve) | Pressure, psi (m)
   PSV (pressure sustaining valve) | Pressure, psi (m)
   PBV (pressure breaker valve) | Pressure, psi (m)
   FCV (flow control valve) | Flow (flow units)
   TCV (throttle control valve) | Loss Coefficient
   GPV (general purpose valve) | ID of head loss curve

2. Shutoff valves and check valves are considered to be part of a pipe, not a separate control valve component (see [PIPES]).
