Control Valves
Emech™ Digital Control Valves
Emech™ is digital hardware that is faster, simpler, and smarter with one goal
in mind: unparalleled performance in industrial applications. Emech™ digital
control valves are available for steam/water and hot/cold water industrial
service. The unique range of Emech™ multi-patented ceramic disc/stainless
steel disc rotary 3 port mixing when combined with the Emech™ digital
actuator delivers superior closed-loop performance in terms of speed,
precision and reduced mechanical wear when compared to traditional mixing
and control valve systems.
The mixing valve system is a highly optimized temperature control system
with patented valve disc system, swirl mixing action, high speed in valve
sensing, with embedded PID control of a 100% duty cycle rated stepper
motor digital actuator.
A series of 2 port flow control valves are also available, which when
combined with the Emech™ actuator and sensing technology forms a
system providing superior temperature control to a range of industry
standard processes, through its high speed and software configurable
control dynamics.

•
Decrease production downtime, improve product
consistency and boost revenue.
Emech™ Digital Control Valves are specifically
designed to instantly respond accurately. Emech™’s
response time is incredibly rapid which directly
affects productivity. The technology of Emech™
simply achieves more in less time, increasing
productivity while lowering utility and maintenance
cost. Emech™’s superior valve performance allows
manufacturers to run their plans closer to constraints,
thereby increasing production and yield.
