Siemens VVG41.32 two-way control valve — a reliable seat valve for precise flow control. Precision control in heating, cooling, and steam systems. Siemens VVG41.32 is a high-quality 2-way (straight-through) seat control valve with external thread, designed for heating, ventilation, air conditioning, and steam circuits. With nominal diameter DN32 and flow capacity Kvs 16 m³/h, it is ideal for medium circuits: fan coil units, heat substations, boiler rooms, underfloor heating systems, supply ventilation, cooling, and operation with saturated/superheated steam. German Siemens Acvatix series quality ensures high accuracy, excellent tightness, and exceptional durability in a wide range of operating conditions. Main technical specifications: Valve type: 2-way seat control valve (straight-through); Nominal diameter (DN): 32 mm; Flow capacity (Kvs): 16 m³/h; Working pressure: PN16 (up to 16 bar); Medium temperature: from -25°C to +150°C; Connection: external thread G2" (according to ISO 228/1); Body material: high-quality bronze CC491K (Rg5); Stroke: 20 mm; Control characteristic: equal percentage; Leakage: 0…0.02% of Kvs; Application: water, water-glycol solutions, brines, saturated and superheated steam (open and closed circuits). Perfectly compatible with Siemens actuators of SAX, SKD, SKB series and others with 20 mm stroke. Advantages of Siemens VVG41.32: High control accuracy — equal percentage characteristic ensures smooth flow control and maximum energy efficiency. Excellent tightness — minimal leakage (class A) for increased system efficiency and reduced losses. Wide application range — works with water, brines, and steam in the range from -25°C to +150°C.
