KPF balance valve

Brand：Pneumatic eccentric butterfly valve 型号：KPF-16

The following is detailed information about KPF balance valve:
1. Product definition and classification
KPF balance valve is a special function regulating valve mainly used for hydraulic balance control of heating and air conditioning systems. According to the adjustment method, it can be divided into:
Static balance valve (manual adjustment): The flow rate is adjusted by changing the clearance between the valve core and the valve seat, which requires manual debugging and locking of the opening.
Dynamic balance valve (automatic adjustment): automatically adjusts the opening according to the system pressure difference to maintain a constant flow rate or pressure difference.
2. Core functions and working principles
Flow regulation: By rotating the handwheel to change the valve core opening, the flow area can be adjusted to change the fluid resistance and achieve flow distribution.
Hydraulic balance: solves the problem of "uneven heating and cooling" in heating/air conditioning systems, avoiding the phenomenon of "large flow, small temperature difference".
Flow measurability: Equipped with a pressure measuring small valve, the actual flow rate (Q=Kv × √ Δ P) is calculated by measuring the pressure difference (Δ P) combined with the flow coefficient (Kv value).
3. Technical parameters
Nominal pressure: 1.6 MPa (some models support higher pressures).
Diameter range: DN15~DN600, covering small caliber (such as DN25) to large caliber (such as DN500) requirements.
Applicable medium: Non corrosive liquids such as water and oil, with a temperature range of 0-100 ℃.
Material: The valve body is commonly made of gray cast iron or stainless steel, the internal components are made of stainless steel or cast copper, and the sealing material is rubber or asbestos.
4. Installation and commissioning
Installation location: It is recommended to prioritize installation in the return water pipe, especially in high-temperature circuits, for easier debugging.
Debugging method: Use a dedicated intelligent instrument to debug and lock the opening without the need for a separate shut-off valve.
5. Application scenarios
HVAC system: centralized heating and air conditioning terminal equipment to solve the problem of uneven temperature distribution at room temperature.
Industrial field: Flow control of non corrosive liquid pipelines in chemical, petroleum and other industries.
