Special options for high temperature or emissions control are available upon request. 4–20 mA and 0–10 vdc control options can be provided with either pneumatic or electric actuators. For large diameter diverting or mixing applications, 3-way butterfly valve assemblies can be provided to minimize cost.
2-way & 3-way characterized port ball valves with 100:1 turn down are extremely cost effective with a high Cv compared to valve size.
The unique DeltaP “pressure independent” control valve is the technology for the future and will precisely maintain flow, based on a control signal, regardless of pressure fluctuations across the supply and return lines. This efficiency will also allow for significant energy cost savings on large centralized chilled water systems.
