HTCCV - Suitable for Low Pressure Steam and High Temperature Water Applications

DN PICCV

The High Temperature Characterized Control Valve (HTCCV) meets the challenges of space restricted applications such as unit ventilators, and fan coil units. It is available with spring and non-spring return actuators. The HTCCV is is suitable for steam and or high temperature water.

Belimo's HTCCV is very unique. A special characterizing disc inside the valve gives it an equal percentage characteristic which makes it out perform a globe valve of the same nominal size. The flow (Cv value) is reduced to the required value by a combination of the hole in the ball and the shaped aperture in the disc. The increase in flow as the valve is opened is very slow and controlled, and it also reduces turbulence. This produces better part-load behavior and improved stability of control while also optimizing energy consumption.

The HTCCV controls a steam supply of 15 psig and less, which out performs a globe valve of similar size and Cv. Within the ½” to 1” sizes, a globe valve is no match for the HTCCV.

The HTCCV features:

  • Dezincificated brass body ensures the mechanical strength and integrity of the valve in critical steam applications.
  • Controls a steam supply of 15 psig and less.
  • Maintenance free, no repacking required after being in service for an extended period of time.
  • Designed to fit in compact areas where on/off or floating point control is required using 24 VAC.

The HTCCV is typically used in air handling units on heating or cooling coils, and fan coil unit heating or cooling coils. Other common applications include unit ventilators, VAV box re-heat coils and bypass loops.
