ZW209Q Pressure Reducing Valve with Downstream Surge Protection
ZW209Q is a pressure reducing valve used where a sudden decrease in downstream demand can create a pressure surge in the plumbing system.
Maintains the downstream pressure within narrow limits, regardless of inlet pressure fluctuations or varying flow rates.
In the event of a pressure surge created by a sudden decrease in downstream demand, the ZW209Q will close rapidly, protecting the plumbing system.
Once the surge dissipates the ZW209Q will return to normal operation.
