FEATURES • Small size allows installation where space is limited • Long stroke results in a high quality characteristic • Soft seat provides low leakage rate and high rangeability • High close-off pressure • Wide standardized range of kVS values • Reduced kVS values in the bypass to facilitate hydronic balancing • Range of fittings available for different connections (compression, soldered, threaded) • Compatible with two-piece Conex compression fittings • Dezincification-resistant yellow brass Trim Stem Plug Suitable medium Controlled water temp. 6.5 mm see Fig. 4, Fig. 5, and Fig. 6 on page 6 and Fig. 7, Fig. 8, and Fig. 9 on page 7 2-way: modified equal % 3-way: A-AB modified equal %; B-AB linear ON/OFF valves VSOC-xxx Stroke 2.5 mm Copyright © 2017 Honeywell Inc. • All rights reserv

FLOW CAPACITIES AND CLOSE-OFF PRESSURE RATINGS VSxC-2 Two-Way Valves with Conical Sealing

VSxC-4 Four-Way Valves with Conical Sealing DN

Three-Way Valves with Bypass These valves simplify the installation, which is depending on the layout of the pipework, as the bypass pipe is part of the valve. The information for the normal three-way valves is also valid for this type. In the case of the two-way valve, the three-way valve, and the three-way valve with bypass, the built-in spring produces a closing force on the A-B / A-AB ports. The valves are supplied with a screwed-on adjustment cap for manual operation and for protection of the stem. At modulating valves with 6.5mm stroke the adjustment cap allows A-B / A-AB to be fully...

Valves VSxC-2 need two connection sets, valves VSxC-3 need three connection sets, and valves VSxC-4 need four connection sets. *Cannot be purchased from Honeywell order number dimensions of connection sets
