The pilot operated reducing valve PR500 reduces a higher up stream pressure to
a constant lower down stream pressure. This very accurate valve is designed to
operate with a minimum of maintenance. The only moving parts in the valve are
the diaphragm and the stem assembly, which are guided by an exchangeable
bearing in the cover and the valve seat. The Watts PR500 is easy to install and
adjust. It is available with flanges (DN50-DN250).
Max. temperature: 70°C Continuous
Note: WRAS Approval applies on sizes up to and
including DN250 for above ground applications
on water systems to a maximum 20ºC.
