1.Pressure-Balanced Plug Design
Feature: The plug adopts a pressure-balanced structure, which significantly offsets the axial thrust exerted by the medium pressure on the plug.
Advantage: Manual adjustment or operation remains effortless and smooth regardless of system pressure, ensuring higher commissioning accuracy.
2.High Flow Coefficient
Feature: Optimized internal flow path design provides a higher Kv value.
Advantage: Minimizes resistance (pressure drop) at the same flow rate, reducing system energy consumption and achieving building energy savings.
3.Precise Numeric Handwheel
Feature: Equipped with a clear digital scale display (typically accurate to 0.1 turns).
Advantage: Operators can intuitively read the current valve opening, facilitating repeatable settings and precise commissioning.
4.Full Shut-off Function
Feature: Beyond its balancing function, the valve provides excellent sealing performance.
Advantage: It can serve as an isolation valve during system maintenance or equipment repair, eliminating the need for additional shut-off valves.
5.Self-sealing Test Ports
Feature: The valve body is equipped with two self-sealing measurement points.
Advantage: Allows rapid connection of differential pressure gauges or flow meters for flow measurement, venting, or draining without leakage upon removal.
6.Premium Materials & Wide Range of Specifications
Materials: Large-diameter bodies are typically made of Ductile Iron (QT450-10) with stainless steel plugs and stems; small-diameter models (below DN50) are made of brass.
Range: Covers DN15 to DN500; pressure ratings include PN16 and PN25.
