2 DESCRIPTION The VJ series 2-position hydronic valves are used in domestic and small coercial applications to control the flow of hot and/or cold water. They consist of an actuator and a valve. 3-way valves can be piped for either diverting or mixing valve applications in domestic central heating and/or cooling systems. Both versions can be used to control individual fan coil, baseboard radiator, convector heat exchanger in combi boiler applications. Depending on the model selected they can be controlled by a low or line voltage SPST controller, such as a room thermostat, aquastat or flow switch. The 2 wires Vdc version can be controlled by a -10Vdc/20Vdc reverse-phase system. The actuator head is removable without affecting the integrity of the water system. All actuator versions are interchangeable with any valve body, offering the highest flexibility for boiler production line assembly and maintenance. 3-way valves are suitable for both diverting water from AB to A or to B and from A or B to AB.

3 FEATURES 3-way body Wide variety of pipe connections including: DIN ISO 228 (male) Quick connection Cartridge can be used to be integrated in customized water manifold Control by a low or line voltage SPST or SPDT control, and Vdc version with DPDT controller 24 Vac actuators available. for Vdc version: - to push : 20Vdc ±10%, max current 250mA - to pull : 10Vdc ±10%, max current 150mA - switch off after 5 s. required Quick connect electrical connections Minimal actuator power consumption C fluid temperature (peaks 130 C) C ambient temperature Quick and easy replacement of moving parts Actuator head installation does not require draining of the system. Max. differential pressure 0,6 bar. 3 EN2R R2-NE

4 CONSTRUCTION AND OPERATION All moving and sealing parts of the valve are constructed in the cartridge assembly. The piston is sealed with O -rings. When the piston driven down port B is sealed, allowing flow between port AB and port A. With the stem up the flow is between port AB and port B. The VJ series hydronic valves offer a variety of versions of pipe connections to suit the different applications. The valve pressure loss characteristic is dependent on the pipe connection/dimensions For the actual valve rating please refer to the specification section. A A AB AB B Fig. 1. Flow direction B Operation The movement of the electric actuators is produced by a screw spindle which is driven in both directions by a synchronous motor through a set of gears. The motor is switched OFF electronically when the actuator reaches the end positions. The actuators are fixed to the valve body by means of a coupling ring requiring no tools for mounting. The actuators are maintenance-free and furnished complete with a ready-to-wire connecting cable ~ Fig. 3.

8 INSTALLATION IMPORTANT Take care that installer is a trained experienced service person. When installing this product read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition. Check the ratings given in the instructions and on the product to make sure it is suitable for your application. Always conduct a thorough checkout after installation. CAUTION Switch off power supply before making electrical connections to prevent electrical shock and equipment damage. It is advisable to remove the actuator head from the valve body for ease of installation. Fit the actuator head in the most convenient position for wiring. On sweat fitted valves, the cartridge is shipped loose or is removed to avoid being damaged during the solder operation. On 24 Volt systems, never short circuit the valve coil terminals as this may burn out the heat anticipator in the thermostat. To remove the actuator head 25 clearance is needed above the actuator. Plumbing (see fig. 6.) The valve may be plumbed in any angle but preferably not with the actuator head below the horizontal level of the valve body. Make sure there is enough room around the actuator head for servicing or replacement. When used to form a part of a central heating system, do not locate it where it will block the system vent, cold feed or any bypass when the valve is closed Mount the valve directly in the tube or pipe. Do not grip actuator head while making and thightening plumbing connections. Either hold valve body in your hand or attach adjustable spanner across the hexagonal or flat faces on the valve body. To install a replacement actuator head IMPORTANT Installation of a new actuator head does not require draining the system providing the valve body and cartridge assembly remain in the pipe line. Disconnect power supply before servicing to avoid electrical shock or equipment damage. Disconnect Molex TM connector and remove. Where appropriate, label wires for rewiring. Remove the clip (1) and pull the actuator (2) NOTE: The actuator can be installed at 360. Install the new actuator head by reversing the process. Reconnect Molex TM connector. Restore power. 2 Fig. 6. Remove actuator 1 EN2R R2-NE 8

9 ADJUSTMENT, CHECKOUT AND SERVICE Checkout Raise the setpoint of the thermostat above room temperature to initiate a call for heat.. Service WARNING The VJ series hydronic valves should be serviced by trained, experienced service personnel. If the valve is leaking, drain system or isolate valve from the system. Check to see if the cartridge needs to be replaced. If the gear train of the motor is damaged, replace the actuator assembly. NOTE: The VJ series hydronic valves are designed and tested for silent operation in properly designed and installed systems. However, water noises may occur as a result of excessive water velocity. Piping noises may occur in high temperature (over 100 C) systems with insufficient water pressure. 9 EN2R R2-NE
