ABOUT GLOBE CONTROL VALVES
The SPIRA-TROL and M-Series Globe Control valves
are general purpose control valves that can
be engineered to solve both complex and
basic requirements. Their robust construction
makes them long-lasting and easy to maintain,
while their modular design makes them easy to
specify, reducing spares inventory requirements.

CLAMP IN PLACE, FREE FLOAT DESIGN
The entire Spirax-Mitech range of control valves utilises
the clamp in place, free float design. All trim components
are designed to clamp in place so the valve can be quickly
configured to the users specific process needs. The free
float of the seat and plug during assembly means that
stem, plug and seat alignment is easily achieved. When
compared to alternative designs, the free float designs
provides the user with longer stem seal life and better
valve shut-off performance.
The simplicity of build also means that maintenance is
quick and easy, with no special tools required to achieve
the design performance of the valve.
