TLX Technologies has introduced new 4-way and 3-way switching valves as part of its modular valve family . These high-flow valves offer near-zero cross-flow leakage , enhancing thermal efficiency and flow control in vehicle thermal management systems . Key features include position maintenance without constant power and an efficient fluid flow path that minimises pressure drop . These characteristics help reduce overall energy consumption , improving mileage or range across various fuel types . |
The valves support both 12 and 24 Vdc operations and can use either PWM or LIN communication protocols . Design teams can select port sizes up to 25.4mm without altering the valve body , flow paths or drive system . This flexibility allows OEM and system design teams to adapt the valves to multiple vehicle platforms with different communication protocols , operating voltages and port size requirements , offering versatile thermal management controls . |
Danfoss has launched its new AME 110NL ( X ) modulating actuators for AB-QM 4.0 pressure independent balancing control valves . These actuators replace the existing AME 110NL ( X ) and AME 120NL models , offering significant upgrades to enhance hydronic HVAC system performance and efficiency . Designed for AB-QM 4.0 Pressure Independent Control Valves ( PICV ) in the DN 15-32 range , the new actuators feature a built-in digital step motor with |
4,000 positions over the full valve stroke , a 15-fold increase in resolution compared to the previous 256 steps . Key improvements include an upgraded IP rating from IP42 to IP54 , allowing installation in any direction , and support for both 24V AC and DC power supplies with automatic detection . The actuators offer selectable speeds of 3 or 12 sec ./ mm and feature advanced electronic calibration and valve stroke detection for optimal performance and easy setup . |
