Description
Constant volume flow in a compact water circuit
The Belimo C215QFL-E pressure-independent flow limiting valve (PIFLV) is specially designed for pressure-independent limiting or control of water flow in HVAC systems. The valve helps maintain the design flow per circuit without pressure fluctuations directly leading to excess flow. The DN15 sizing clearly indicates the pipe diameter for which this version is intended.
By combining flow limiting and valve function, a clear solution is created for hydraulically balanced terminal units. The circuit receives the required water flow, while unnecessary flow is limited.
Important features & benefits
