PC320
PN25/ 350PSI
PC320 bronze differential pressure control valve, designed with a low-resistance Y-shaped structure, provides more accurate and stable control in the variable flow system, automatically and keeps the differential pressure between both ends of the control valve at a relatively stable value, with no external power source needed. The high-precision disc and reliable sealing performance ensures precision and durability in flow measurement. PC320 is mainly used in the HVAC system
Relying on the pressure change of the high/low pressure chambers to change the valve opening angle, automatically keeping differential pressure constant.
Large controllable pressure differential range.
Valve shut-off function.
differential Pressure value can set at site.
Pressure measuring connections on both side.
Vent hole in high pressure chamber.
Lower noise.

In valve installation, it is strongly suggested that sufficient space should be left for easy maintenance in the future. A strainer shall be mounted in front of the valve to prevent foreign matters from blocking the valve.
