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.
Automatic water flow balancing valve.
The flow rate would be the flow rate calculated by the engineer.
Automatic flow limiting valves do not require any additional balancing as do manual balancing valves therefore they reduce labor costs from not having to balance and rebalance the valves.
These valves are factory set to a given gpm within a pressure range.
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.
Shut off function with position indicator separate from setting function.
In my opinion the better recirculation flow balance solution would use automatic flow limiting valves valves similar to the griswold lead free k valve.
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.
Automatic balancing valves are utilised in central heating and cooling systems that rely on flow of water through the system.
The pressure drop range is also easy to determine.
Valve should be delivered with threaded impulse tube connection.
The valves also have a brass venturi flow element for greater accuracy and allow for manual balancing and shut off.
