Static Manual Balancing Valve PHF**7B Application
�
�
PHF**7B series screw static balancing valve is a key hydraulic balance product used for precise flow regulating of water pipelines system in HVAC application to ensure static hydranlic balance across whole water system.
�
PHF**7B series can ensure the actual flow of each terminal equipment and pipeline� in line with
the design flow in the phase of system initial commissioning by site commissioning with flow measuring
computer.�
�
PHF**7B series are widely used in main pipes, branch pipes and terminal equipment pipelines
in HVAC�� water system, It also can be used in other application with the same function requirement.
�
PHF**7B series�scew static balancing valve is a two-way manual , high accuracy flow regulat
ing valve, with the dimensions of DN *0~DN *0 , which is composed of valve housing, valve seat, test cocks, handwheel and stroke indicator,� etc.

Static Manual Balancing Valve PHF**7B Features�

* 1. Ideal adjustment performance
* 2. Excellent cut-off function
* 3. Theory flow curve is equal-percentage
* 4. National patent type opening and closing lock-in
* 5. Every full circle has settled KV, flow through valve body
������ measuring differential pressure at both ends of valve body
* 6. Reliable sealing property.can be calculateddevice.curve
* 7. Strong resistance to corrosion,long life time
* 8. Inner up-down valve stem, there is no need to preset
������ operation room.
* 9. EPDM O-ring sealoperation room.
* *0. *5 degree angle between the core, stem and the axis of
������� the valve makes better flux.
* *1. Inside displacement of core. The position of stem and
and handwheel keep the same when opening or closing
the valve. It is suitable for small place.
* *2. DZR dezincification copper alloy component.
