General
ACTIVAL Model VY54X0F is a series of motorized three-way
valves with flanged connection. The valve and the actuator
are integrated in a single unit.
The valve size ranges from 2" to 3".
The actuator has a reversible synchronous motor, which
operates at a low voltage of 24 V AC.
Control signal is 4 to 20 mA DC input. Executes proportional
control in combination with a single loop controller (e.g.,
Model SDC15).

standards. ACTIVAL Model VY54X0F is the valve and actuator integrated into a single unit. Do not combine the valve with any other actuator, or do not combine the actuator with any other valve. To remove foreign substances inside the pipes, install a strainer (with 40 or more meshes) on the inflow side of each valve. -
Page 9: Mounting Position
When installing the ACTIVAL to pipes, do not allow any object, such as chips, to get inside a pipe or valve. Valve cannot fully close, or the valve seat may get damaged causing fluid leakage, due to an object jammed inside the valve. - Page 10 Disconnect the power from the ACTIVAL before manually operating the ACTIVAL. As shown in Fig. 12, from the front of the ACTIVAL, hold the joint using a tool such as a wrench, and turn the joint slowly toward the set position.

Page 16: Inspection And Maintenance
Inspect the ACTIVAL according to Table 1. Manually open/close the ACTIVAL at least once a month if it is left in inactive state for a long period. Visually inspect the fluid leakage of the valve and the actuator operations every six months. If any of the problems described in Table 2 are found, take corresponding actions shown in the table. - Page 17 AB-7356-U This blank page is added for page layout purposes.
