Product description

The Siemens SQX62U is an electronic valve actuator designed for 2-port and 3-port Siemens valves. It operates on AC 24V and utilizes proportional control signals (DC 0-10 V, DC 4-20 mA, or 0-1000 Ω) to achieve precise positioning. With a powerful 700 N of positioning force and a 20 mm stroke, it ensures reliable operation for demanding HVAC and hydronic applications.

This actuator is ideal for controlling chilled water and hot water systems. It mounts directly onto compatible Siemens valves and offers features such as manual adjustment, position indication, and UL approval for the SQX62U variant. Its robust design ensures durability in environments with medium temperatures ranging from -25°C to 140°C.

Source your Siemens SQX62U valve actuator from Stanlo Automation, your trusted veteran-owned surplus parts distributor. We provide reliable, high-quality components with expert service, ensuring your industrial automation needs are met efficiently and cost-effectively.
