Valve and actuator replacement is at the expense of others. 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. The ball valve is adjusted by a rotary actuator. The actuator is controlled by a commercially available modulating or floating point control system and moves the ball of the valve – the throttling device – to the position dictated by the positioning signal. Open the characterized control valve counterclockwise and close it clockwise. Equal percentage flow control is ensured by the special design of the ball. With a differential pressure of 16…350 kPa, a constant flow volume is achieved thanks to the integrated pressure regulating valve. Independently of the differential pressure through the valve, a valve authority of 1 is achieved. Even with pressure variations and in the partial load range, the flow rate remains constant with each respective opening position (angle of rotation) and ensures a steady control. The ball valve can be installed upright to horizontal. The ball valve may not be installed in a hanging position, i.e. with the spindle pointing downwards. Belimo valves are regulating devices. For the valves to function correctly in the long term, they must be kept free from particle debris (e.g. welding beads during installation work). The installation of a suitable strainer is recommended. Ball valves and rotary actuators are maintenance-free. Before any service work on the final controlling device is carried out, it is essential to isolate the rotary actuator from the power supply (by unplugging the electrical cable if necessary). Any pumps in the part of the piping system concerned must also be switched off and the appropriate slide valves closed (allow all components to cool down first if necessary and always reduce the system pressure to ambient pressure level). The system must not be returned to service until the ball valve and the rotary actuator have been correctly reassembled in accordance with the instructions and the pipeline has been refilled by professionally trained personnel.Z2075QPTPF-G • en-us • 2022-04-01 • Subject to change3 / 4 The direction of flow, specified by an arrow on the housing, is to be complied with, since otherwise the ball valve could become damaged. Please ensure that the ball is in the correct position (marking on the stem). The angle of rotation of the CQ.. actuator can be changed by end stop clip in 2.5° increments. This is used to set the V'max value (maximum flow rate of the valve). Remove end stop clip and place at desired position. After every change of the flow setting by means of end stop clip, an adaptation must be triggered on the modulating actuators.

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/DC 24 V. Angle of rotation is adjustable with the integrated mechanical stop. 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. Actuators may also be powered by DC 24 V. Actuators with plenum cable do not have numbers; use color codes instead. One built-in auxiliary switch, 1x SPST 1A @ 30 VDC (resistive load), for end position indication, interlock control, fan startup, etc. Apply only AC line voltage or only UL-Class 2 voltage to the terminals of auxiliary switches. Mixed or combined operation of line voltage/safety extra low voltage is not allowed. Meets cULus requirements without the need of an electrical ground connection. 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. AC 24 V TransformerAuxiliary SwitchNext >
