Azbil ACTIVAL PN16 Specifications & Instructions

Motorized Two-Way Valve with Flanged-End Connection
for High Differential Pressure Application
<4-20 mA DC Input with 4-20 mA DC Feedback Output>
General
ACTIVAL™ Model VY5199J for high differential pressure
application is a series of motorized two-way valves with
flanged-end connection. Rotary valve and actuator are
integrated in a single unit.
Valve size ranges from DN15 (1/2") to DN150 (6"), and
valve body rating corresponds to ISO PN16.
Actuator has a reversible synchronous motor, which
operates at a low voltage of 24 V AC.
4-20 mA DC input control signal provides proportional
control in combination with a PLC (e.g., Model R35/R36).
∗ PLC: Programmable Logic Controller
Features
• Applicable to high differential pressure applications:
Water flow is controlled inside the valve to prevent over
pressure drop, leading to cavitation erosion resistance.
(See Fig. 1.)
• Compact and lightweight:
Rotary motor actualizes small body and light weight.
• Valve and actuator integrated in a single unit:
Pre-assembled body requires no adjustment.
• Durable actuator with low power consumption
• Modified linear flow characteristics
• Valve applicable to high differential pressure, high Cv
value, wide rangeability, and low leakage
• 4-20 mA DC output available for position feedback.
• Open/close changeover for input signal failure:
Actuator fully opens/closes valve in case that the control
signal is not input to the actuator. (Default: Fully open)
• Direction changeover of control action:
Open/close action by 4-20 mA DC input signal is reversely
controllable.
Normal action 4 mA: 0 % to 20 mA: 100 %
Reverse action 20 mA: 0 % to 4 mA: 100 %.
(Default: Normal action)

• Adjustable dead band*:
Dead band width can be narrowed to more precisely
operate valve actuator.
∗ Actuator is not operated by input signal changed less than a
certain amount. This amount of change is called dead band.
• CE Marking certified:
ACTIVAL Model VY51 conforms to all the applicable
standards of CE Marking.
