The only electrically actuated ball valve in this range, the DQF Series combines full bore flow design with automatic 90° rotation control. With 11 models covering port sizes from 3/8" to 3-1/8" and Kv values from 5.7 to 200 m³/h, it provides reliable remote shut-off for commercial and industrial refrigeration systems requiring automated flow control.
Manual Ball Valve — Full Bore, Brazed ODF (HBC Series)
Offering the widest port size range in this catalog, the HBC Series features a full bore design with TIG welded copper body and bidirectional flow capability. With 16 models covering 1/4" to 3-1/8" and Kv values up to 700 m³/h, it is available with or without a charging port for flexible system integration across commercial and industrial refrigeration applications.
Manual Ball Valve — Reduced Bore, Brazed ODF (QFT Series)
A precision-forged copper ball valve with reduced bore design, the QFT Series offers 10 models covering port sizes from 1/4" to 2-1/8". Available with or without a charging port (designated by the V suffix), it features specially selected seals compatible with common refrigerants and a secondary reliable sealing structure at the valve stem for enhanced leak prevention.
CO₂ Ball Valve — Full Bore, Brazed ODF, 120 bar (QF-CO2 Series)
Engineered specifically for transcritical CO₂ refrigeration systems, the QF-CO2 Series features a precision-cast valve body with integrated stainless steel tube and full bore design for flow without pressure drop. With 8 models covering port sizes from 1/2" to 2-1/8" and a maximum working pressure of 120 bar, it uses specially selected CO₂-compatible seals for reliable operation at extreme pressures and temperatures.
Threaded Ball Valve — NPT Connection, Forged Copper (GFM-S Series)
The only NPT threaded ball valve in this range, the GFM-S Series features a precision-forged copper body with NPT threaded connections that enable tool-free installation and removal without welding. With 5 models covering NPT 1/4" to 1" and bidirectional flow capability, it is compatible with most common refrigerants and suitable for applications where brazed connections are impractical.
