PC500
PN20/300PSI
PC500 brass differential pressure control valve adopts a low-resistance upright structure. It provides precise and stable control in variable flow systems, automatically maintaining a constant differential pressure across the valve within a relatively stable value, without any external power supply. The high-precision disc and reliable sealing performance ensures precision and durability in flow measurement. PC500 is mainly used in the HVAC system.
Relying on the pressure change of the high/low pressure chambers tochange the valve opening angle, automatically keepingdifferential pressure constant.
Wide controllable pressure differential range.
On-site pressure differential setting available.
Optional pressure measurement ports.
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.
