Motorize Controll Valve Steam Azbil

Overview
ACTIVALTM Model VY51_ _J 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 DN80 (3”), and valve body rating corresponds to ISO PN16.

Actuator has a reversible synchronous motor, which operates at a low voltage of 24 V AC.

5 kinds of control signals are available to operate ACTIVAL.

1. Nominal 135 Ω feedback potentiometer (built-in):
Provides proportional control in combination with a DDC
controller (e.g., InfilexTM GC Model WY5111).

2. Nominal 135 Ω resistance input:
Provides proportional control in combination with a
proportional controlled electric controller (e.g, Neostat
Model TY900_Z, Model TY9800).

3. 4-20 mA DC input:
Provides proportional control in combination with a DDC
controller (e.g., InfilexTM GC Model WY5111, Model R35/
R36).

4. 2-10 V DC input:
Provides proportional control in combination with a DDC
controller (e.g., InfilexTM AC Model WY5117).

5. 0-10 V DC input:
Provides proportional control in combination with a DDC
controller.

Features

• 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.

• A variety of control signals available:
- Nominal 135 Ω feedback potentiometer

• Valve for chilled/hot water control and for steam control
applicable to high differential pressure, with large Cv
value, wide rangeability, and low leakage.
* DDC: Direct Digital Control

• Durable actuator with low power consumption.

• Equal percentage flow characteristic.

• 2-10 V DC output (for position feedback) available with
4-20 mA DC input, 2-10 V DC input, and 0-10 V DC input
types.
