Zawór regulacyjny Siemens VXF42.100-160

Siemens VXF42.100-160 (S55204-V143) three-way control valve — powerful flanged valve PN16 for large HVAC systems. High-performance solution for precise control of large flows. Siemens VXF42.100-160 is a modern 3-way seat control valve with flanged connection, designed for powerful heating, cooling and ventilation systems. With nominal diameter DN100 and high flow capacity Kvs 160 m³/h, it is ideal for central heat substations, boiler rooms, chillers, large fan coil systems and supply-exhaust ventilation in commercial, administrative and industrial buildings. German Siemens quality of the Acvatix series guarantees high reliability, excellent tightness and long service life even under intensive use. Main technical specifications: Valve type: 3-way seat valve (mixing/diverting). Nominal diameter: DN100. Flow capacity: Kvs 160 m³/h. Working pressure: PN16 (up to 16 bar). Coolant temperature: from -10°C to +150°C. Connection: flanged according to ISO 7005. Body material: high-strength gray cast iron EN-GJL-250. Stroke: 40 mm. Control characteristic: equal percentage (straight through), linear (bypass). Tightness: 0…0.02% of Kvs (main port), 0.5…2% (bypass). Application: closed circuits with water, water-glycol solutions and brines. Works perfectly with Siemens actuators of SKC, SKD, SAX series and others with 40 mm stroke. Advantages of Siemens VXF42.100-160: Increased strength — PN16 allows use in systems with higher pressure compared to PN10 series. Excellent tightness — minimal leakage ensures energy efficiency and system safety. High performance — handles large coolant flows, guaranteeing.
