For more information go to www.p65warnings.ca.gov * If temperature exceeds 212°F operating range due to a boiler control failure the valve will safely contain the hot water but manufacturers product warranty becomes invalid. Valve and actuator replacement is at the expense of others. Product features The PIQCV zone valves with its pressure independent technology are suited for large commercial buildings where higher close-off and dynamic balancing is required. Common applications include unit ventilators, fan coil units, VAV reheat coils, fin tube casing, radiant panels and duct coils. The valve fits in space restricted areas and can be assembled without the use of tools.

Valve selection should be done in accordance with the flow parameters and system specifications. The actuator is mounted directly to the valve without the need for tools or additional linkage. The actuator operates in response to AC 100...240 V. Angle of rotation is adjustable with the integrated mechanical stop.Technical data sheetCQKBUP-LL www.belimo.usCQKBUP-LL • en-us • 2021-02-18 • Subject to change2 / 2 Electrical installation INSTALLATION NOTES Actuators with appliance cables are numbered. Provide overload protection and disconnect as required. Actuators may be connected in parallel. Power consumption and input impedance must be observed. Meets cULus requirements without the need of an electrical ground connection. Warning! Live Electrical Components! During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury. On/OffNext >
