Application
Use DeltaPValves for the following Applications:
Chilled Water & Heating Water Coils
DeltaPValves installed at cooling and heating coils in the distribution system will stabilize system flow, improve comfort and reduce energy consumption.
Heat Exchangers for District Cooling and Heating
Control heat exchanger flow in district energy transfer stations with the DeltaPValve®. With precise temperature control, stop wasted energy and simplify control strategies and complexity.
Condensing Boiler
Systems
Use DeltaPValves in a heating water system served with condensing boilers to achieve the lowest possible return water temperature, while still minimizing pump energy.
Shut-off and Leakage
The unique design and low internal differential pressure allows the DeltaPValve® to achieve tight close-off, meeting ANSI Class III and IV leakage standards (0.1 % - 0.01 % of rated valve capacity). Actuators are selected appropriately for the torque required to achieve up to 200 PSID [13.8 bar] shut-off.
Maintenance
All seals can be replaced in valves 3” [80 mm] and smaller without removal from the piping system. Valve flow characteristics can be modified in valves 8” [200 mm] and smaller without removal from the piping system.
Actuation Options
All DeltaPValves are factory assembled and shipped complete with actuators. We offer different actuation types for specific applications, including electric and pneumatic, and both fail-safe and fail-in-place operation.
Actuators from most major manufacturers are acceptable. Please contact the factory for more information on actuator options or for specific requests. We have an OEM with KMC for our ½” - 4” valves, but work easily with others.
Warranty
All ½”–8” DeltaPValves are covered by a 10-year warranty, reflecting our long-standing commitment to quality, reliability, and performance. At Flow Control Industries, we believe in solutions built to last — not short-term fixes. With less than 1% valve failure across installed applications, the DeltaPValve® continues to deliver dependable performance and a lower total cost of ownership than traditional control valves on the market.
Made in USA
The DeltaPValve® is manufactured and assembled in Woodinville, Washington, and meets the Buy American requirements in Section 1605 of the American Recovery and Reinvestment Act of 2009 (ARRA).
Installation
The DeltaPValve® can be used for control with chilled water, heating water and glycol fluid systems. Orientation can be horizontal or vertical, with the recommendation to keep the stem and actuator above horizontal.
There are no requirements for straight pipe lengths before or after a DeltaPValve®.
Valve Materials
Body: Valves 1.5” [40 mm] and smaller have brass bodies with female NPT connections. Valve bodies 2” [50 mm] and larger are ductile iron.
Internal Components: All internal components are high quality brass, carbon steel, stainless steel or Teflon. No plastic internal parts are used.
Seals: EPDM.
Field Verifiable Performance
Inlet, intermediate, and outlet P/T ports are vital to verify pressure independent operation, validate flow rates, confirm valve shutoff, and troubleshoot system issues. The DeltaPValve® is the only pressure independent valve with 3 P/T ports.
