HDF Series Flow Control Valve – Zero Pressure Loss Orbital Ball Valve
The HDF series flow control valve is a micro-power electric ball valve designed for gas flowmeter integration and pipeline automation. Adopting an innovative orbital ball valve design with soft sealing structure, it provides zero pressure loss with full bore diameter and low torque operation.
Key Features
Zero pressure loss – Full bore design, valve bore equals pipeline diameter
Working pressure – Up to 0.6MPa (DN≤100) / 0.4MPa (DN>100)
Patented opening mechanism – Reliable operation under medium/high pressure
Intrinsically safe – ExiaIICT4Ga explosion-proof certified
Orbital track control – Advanced stroke control with precision manufacturing
Anodized surface – Corrosion-resistant, easy to clean
Soft sealing – Excellent sealing performance, no internal leakage
