Control valve Siemens VVG41.25

Siemens VVG41.25 two-way control valve — a reliable seat valve for precise flow control. Precision control in heating, cooling, and ventilation systems. Siemens VVG41.25 is a high-quality 2-way (straight-through) seat control valve with external thread, designed for heating, ventilation, and air conditioning (HVAC) systems. With nominal diameter DN25 and flow capacity Kvs 10 m³/h, it is ideal for small and medium circuits: fan coil units, underfloor heating, heat substations, boiler rooms, supply ventilation, and cooling systems. German Siemens Acvatix series quality ensures high control accuracy, excellent tightness, and long-lasting trouble-free operation. Main technical specifications: Valve type: 2-way seat control valve (straight-through); Nominal diameter (DN): 25 mm; Flow capacity (Kvs): 10 m³/h; Working pressure: PN16 (up to 16 bar); Medium temperature: from -25°C to +150°C; Connection: external thread G1½" (according to ISO 228/1); Body material: high-quality bronze; Stroke: 20 mm; Control characteristic: equal percentage; Leakage: 0…0.02% of Kvs; Application: water, water-glycol solutions, brines, saturated and superheated steam (in open and closed circuits). Perfectly works with Siemens actuators of SAX, SKD, SKB series and others with 20 mm stroke. Advantages of Siemens VVG41.25: High accuracy — equal percentage characteristic ensures smooth and efficient flow control. Excellent tightness — minimal leakage guarantees energy efficiency and system safety. Wide temperature range — suitable for heating, cooling, and steam systems. Durability — bronze body is corrosion-resistant, valve requires no maintenance for many years. Easy installation.
