Options
Heavy Spring - suffix KH
The heavy spring option is used in applications
where there is low differential pressure across the
valve, and the additional spring force is needed to
help the valve close. The option is best suited for
valves used in on-off (non-modulating) service.
For assistance in selecting appropriate valve
options or valves manufactured with special
design requirements, please contact our
