The normally closed H118 is a combination Hydramotor
actuator and safety shutoff/control gas valve. It is used
for commercial and industrial burners in applications
such as furnaces, dryers, dehydrators, conversion burners
and heaters.
The cast iron, globe-type valve body features a soft
synthetic seat and integral heavy-duty return spring for
tight and certain closure in one second or less upon
current interruption.
The self contained, hermetically sealed, pull-type electro-hydraulic actuator consists of a motor/pump unit
immersed in oil, reducing wear and provides highly
reliable operation.
