Variable flow primary pumping, min flow bypass valve sizing question
Variable flow primary pumping, min flow bypass valve sizing question
(OP)
Hi guys,
How does this valve get sized?? My approach would be to size it based on the size of the largest boiler/chiller pump. Do you still need to do an authority calc on it ie a 250kpa pump would need a fully open dp of around 65kpa when flowing the largest chiller/boilers water flow. Even though the valve always have the full pump head accross it, does the authority calc tell me anything about the valves ability to control the flow in the bypass??
thanks
