About Econex
Econex manufactures heating system control components, primarily butterfly valves and servo motors for residential and industrial combustion applications. The product line focuses on flow-control and actuator solutions rated to European standards (EN 161, ISO 7005) with DVGW and CE certifications for gas-appliance compatibility. Butterfly valves are available in bare configuration across DN40 to DN150, each rated PN16 with ISO 7005 flanged connections suitable for retrofit and new-build heating circuits. Servo motors span 24V AC and 230V AC supply voltages, delivering 90° rotation in 15 seconds with 4-20mA proportional control and IP54 enclosure ratings; ISO 5211 F07 fastening enables direct coupling to valve stems. All units operate across -10 to +60°C ambient temperature ranges. Compliance includes EC Gas Appliance Directive 90/396/EEC certification for gas-system applications and DVGW approval for heating-circuit isolation. 3G Electric stocks 12 SKUs across the Econex butterfly-valve and servo-motor families, holding inventory in its Woodlands distribution facility for supply to plant engineers, maintenance teams, and procurement specialists across Asia-Pacific and global markets. Product selection emphasizes compact design, modular fastening standards, and straightforward integration into existing heating and combustion-control loops without requiring system redesign.
Frequently asked questions
Common questions about Econex from 3G Electric.
What pressure rating do Econex butterfly valves support, and what flange standard do they use?
Econex butterfly valves across the DN40 to DN150 range carry PN16 pressure rating and conform to ISO 7005 flange standards, enabling integration into heating circuits rated up to 16 bar. This combination suits residential boiler systems, industrial heating loops, and gas-appliance control circuits. All bare models feature threaded ISO 7005 flanges for direct bolt-on installation without adapter plates.
Are Econex servo motors compatible with proportional valve control, and what signal range do they accept?
Econex servo motors (models AB1A1002SE5 and AB1C1002S) accept 4-20mA proportional control signals for linear positioning across the 90° rotation range in 15 seconds. This analog input allows modulating flow rather than binary on-off switching, making them suitable for precision heating-load balancing and energy-management applications. Manual override is available on select models for commissioning and emergency operation.
What approvals and certifications do Econex heating components carry for gas-appliance use?
Econex butterfly valves hold DVGW approval and comply with EN 161 standards for gas-appliance control devices. Certification under EC Gas Appliance Directive 90/396/EEC confirms suitability for gas types 1, 2, and 3. Servo motors carry IP54 enclosure ratings (dust and splash protection) and operate reliably in heating environments, though specific gas-appliance certification depends on the valve–actuator combination selected.
What ambient temperature range do Econex servo motors and butterfly valves operate within?
Econex heating components are rated for -10 to +60°C ambient operation, covering typical boiler rooms, heating plants, and industrial combustion areas without supplemental thermal management. This range accommodates seasonal variation in unheated plant spaces and temporary outdoor installations. Always verify fluid temperature limits separately, as they may differ from air-ambient ratings.
How does Econex butterfly-valve sizing work for heating-circuit selection (DN40 vs. DN100 vs. DN150)?
Econex bare butterfly valves scale from DN40 (small branch circuits, ~15 l/min) through DN100 and DN150 (main distribution loops, 100+ l/min). Valve size selection is driven by circuit flow rate and pressure drop. All sizes maintain the same PN16 rating and ISO 7005 flange pattern, so they integrate into a single heating-distribution architecture without custom fittings. 3G Electric holds stock across all diameters for same-day dispatch.
What is the ISO 5211 F07 fastening standard mentioned on Econex servo motors?
ISO 5211 F07 is a standardized mounting interface for electric actuators coupling directly to valve quarter-turn stems. The F07 bore diameter (10 mm on Econex models) and keyway geometry ensure interchangeability across manufacturers' valves and actuators, reducing engineering time on retrofit projects. 3G Electric can advise on valve–actuator pairing to confirm F07 compatibility.
