Fig. 1934 Pressure Independent Control Valve

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.
