PRODUCT DATA
GENERAL
Single-seated 2-way valves for modulating control of hot /
chilled water in heating, ventilating, and air conditioning
systems.
These valves are designed especially for flow control in
hydraulic systems with high temperatures and pressures,
such as district heating systems. It can also be used in
combination with M6410/M7410 (300 N) actuators as well as
with ML7430/35 and ML6435 (400 N) actuators.
