PICV402202 - Pressure Independent Control Valves

Description

Reliance Valves Cast Iron Pressure Independent Control Valve with test points offers precise and accurate control of the flow rate of water determined by the operating spindle position, independent of the circuit pressure changes. By controlling the differential pressure across the internal control device, the flow rate is kept constant. Utilising an internal flow setting device, the valve retains full stroke modulation and operating pressure can be verified through test points.

• Accurate and stable control of the flow rate of water determined by the operating spindle position independent of the circuit pressure changes
• Flow accuracy +5% of max flow or +10% of set flow, whichever is greater
• Test points for verifying operating pressure
• Equal percentage characteristic curve
• Maximum operating differential pressure of 400kPa
• Full stroke modulation independent from the presetting
• Free of CE marking for DN≤300 (cat. according to Art. 4.3 Dir. 2014/68/EU)
• Robust cast iron body for trouble free service life
• Simple installation with PN16 Flanges
