Description

DZR brass pressure independent control valve, PN25.


Features and benefits:

  • Comprehensive flow range available, allowing for cost effective valve selections.
  • The PICV Elite Prime has up to 70% higher max flow compared to the previous model.
  • Accurate over a wide ΔP range – available in both 400 and 800 kPa variants.
  • Class IV leakage for DN15 LF Class 3.
  • PN25 rated product, suitable for high pressure applications.
  • Design validation testing to BSRIA BTS01.
  • As per Cyclic Testing requirements, valve subjected to 10,000 cycles (equivalent to 15 years of typical service, based on two full stroke cycles per day).
  • Comprehensive testing undertaken for each valve – pressure tested to BS EN 12266-1.
  • Integral test points for verification of ΔP and valve performance.
  • Built in convoluted integral diaphragm.
  • Smaller and lighter design suits applications with a small footprint.


Operation:

  • The PICV shall have a constant control characteristic at all flow settings and control flow rates at differential pressures up to 800 kPa.
  • Flow rates will be externally adjustable, and set point recordable.
  • Integral test points will be fitted to verify setting pressure, allowing pumps to be set at optimum speed to maximize energy savings.
