Neptronic -- GP Series Valves

The Neptronic GP series of valves are dynamic temperature
control valves for use in HVAC applications to control the rate of fluid flow to a specific terminal unit or coil.

The Neptronic GP includes a self-adjustment feature which
enables each valve to be continuously self balancing. This
ensures delivery of precise flow rate required by each terminal unit, independently of pressure fluctuations in the hydronic system, providing balancing at any point at and below the maximum flow rate.

Each valve has an adjustable maximum flow rate setting to
enable flow limitation at maximum input control signal. The
maximum flow rate is set by a combination of dip switches in the actuator.

The flow can then be modulated between the maximum flow
setting and shut-off by varying the input control signal.
