Schneider Electric AV-7600-1 Data Sheet

Application

The AV-7600-1 valve linkage kit is used to field assemble MA-521x, MF-5x13, MP-521x, MP-541x, MP-551x, MPR-561x, and MPR-571x round hydraulic actuators to 1/2” through 2" VB-7xxx series valve bodies only.

Features

• Provides direct couple interface between MA, MF,

, and MPR-5xxx actuators and valve bodies.

• Kit fits all VB-7xxx series valve bodies.

• Optimized linkage springs for maximum close off.

General Instructions

Spring Selection and Calibration

The springs in the AV -7600-1 kit are used with selected actuators for specific valves and/or valve sizes. Reference Table-1.

MA, MF, MP-541x, and MP-55xx actuator positioning is independent of spring selected.

When using a Schneider Electric System 8000 controller or a 4 to 20 mA signal across a 500 Ohm resistor to get the proper voltage.

The black spring used on a normally open valves may eliminate the need for positive positioning actuators.

PNV-145-48 Blue spring is not part of this kit. It is only required for controllers limited to 10 volts or 20 mA maximums.

Used with signals limited to 10V such as 0 to 10 Vdc and 4 to 20 mA across a 500 Ohm resistor. Note a reduced control range.

The small unpainted spring may be added to provide addition close off.

The AV-601 linkage extension provides thermal insulation between the valve and actuator. It

is required for all heating valves with MF-5x13, MP-541x, MP-551x, MPR-561x, MPR-571x, and MPR-581x actuators. It is recommended for cooling valves with MF-5x13, MP-541x, MP-551x, MPR-561x, MPR-571x, and MPR-581x actuators. It is also used for higher ambient and fluid temperatures with MA-521x and MP-521x actuators. Re fer to AV-601 Linkage Extension Kit General Instructions, F-26280 for installation procedures.
