PresCal™ HP, High flow pressure reducing valve (NPT, high range)
Product Description
High flow pressure reducing valve (NPT, high range)
High performance piston type pressure reducing valve for high rise buildings and other applications where high pressures are present and require staged pressure control.
The 536A series carries out the first stage pressure reduction in a two valve series where the pressure ratio between the inlet and outlet would be too high for a single pressure reducing valve to control.

Faq - Frequent questions
I have a pressure rise problem downstream of the pressure reducing valve, what can I do?
It may be a problem of a dirty reducing valve or a rise in pressure due to a rise in temperature downstream of the reducing valve as the result of a boiler without an expansion vessel. To check, just switch off the boiler to see whether the pressure rises or not.If there is no domestic water heating system, the reducing valve is dirty. Normally, you will only have to clean the cartridge to reset correct operations.
