Use

The control valves are mixing or throughport valves with the ready fitted magnetic

actuator for position control and position feedback. The short positioning time, high

resolution and high rangeability make these valves ideal for modulating

∂ control of chilled and low-temperature hot water systems

∂ control or dosing control of fluids containing mineral oil (SAE05...SAE50), mineral-oil-

based diesel fuels, heat transfer oils

in closed circuits.

Delivery Valve body and magnetic actuator form one assembly and cannot be separated. The threaded fitting sets and blank flanges are packed and supplied separately. Replacement electronics module ASE1, ASE2 Should the valve electronics prove faulty, the electronics module must be replaced by the ASE1 (DN 15…32) or ASE2 (DN 40…65) replacement electronics module. Mounting Instructions no. 35678 are included. Rev. no. See overview, page 16.

Note for media other than water When sizing valves for media other than water, note that the medium properties ∂ specific heat ∂ density ∂ kinematic viscosity differ from water. All variables depend on temperature. The design temperature is the lowest medium temperature in the valve. Note on viscosity Viscosity may change considerably on temperature changes depending on the medium.

Engineering notes Conduct electric connections in accordance with local regulations on electric installations as well as the internal or connection diagrams. Attention Observe safety regulations and restrictions designed to ensure the safety of people and property at all times! Fit a strainer upstream of the valve to increase reliability. Do not touch hot surfaces.

Installation notes ∂ The MXG..461.. valves are flat-faced allowing sealing with the gaskets provided with the ALG..3 set of 3 threaded fittings. ∂ Do not use hemp for sealing the valve body threads. ∂ The actuator may not be lagged. For notes on electrical installation, see "Connection diagram". Maintenance notes The valves and actuators are maintenance-free. The low friction and robust design make regular servicing unnecessary and ensure a long service life.
