Automatic Water Flow Balancing Valve

In my opinion the better recirculation flow balance solution would use automatic flow limiting valves valves similar to the griswold lead free k valve.

Automatic water flow balancing valve.

Shut off function with position indicator separate from setting function. Automatic balancing valves are utilised in central heating and cooling systems that rely on flow of water through the system. This is accomplished by an adjustable spring loaded balancing valve factory set to automatically regulate the downstream pressure. The valves also have a brass venturi flow element for greater accuracy and allow for manual balancing and shut off.

These manual balancing valves feature a blowoutproof stem with double epdm o ring seals a union with an epdm o ring seal an adjustable memory stop and dual pressure temperature ports. They use the latest flow technology to ensure that the design flow rate is achieved at all times irrespective of any pressure changes within the system. Visible presetting from all sides. High flow pressure valve model c150ehf when properly installed will regulate high upstream inlet pressure to a lower regulated downstream outlet pressure constant pressure within a range regardless of water flow.

These valves are factory set to a given gpm within a pressure range. Isolator r isolator y and k valves are available with a wide range of flows and psid ranges and are the perfect choice for tight spaces. The flow rate would be the flow rate calculated by the engineer. Automatic balancing partner valve with presetting flowverification and shut off to be mounted in the supply line and connected to automatic balancing valve with impulse tube.
