High performance piston type pressure
reducing valve for high rise buildings and

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.
Max. working pressure: 360 psi.
Max. working temperature: 180°F.
Pressure setting range: 90 – 150 psi
Factory setting: 115 psi
