Description
Bettis Switching Relays are pneumatic/hydraulic
poppet style switching devices — manual or pilot
operated — for use with high or low pressure
control applications. In pneumatic service, they
can operate with high pressure gas to 1500 psig, or
to 150 psig in low pressure service. The switching
relays are also available as hydraulic models,
operating to a maximum of 2160 psig. The Bettis
relays are available as 3-way and 4-way 2-position
bodies with a range of switching options including
pneumatic or hydraulic pilot, mechanical and
manual lever.
