General Description

The HOV1 is an underported, globe-type, fuel oil valve

with

a single, quick-opening, stem-guided seat. This 2-way

normally closed, bronze safety shutoff valve features a

spring-loaded stem which, upon power interruption,

drives the teflon seat firmly closed within one second. The

HOV1 is available with or without valve seal overtravel

interlock (FM proof of closure).

The

electrohydraulic

actuator consists of a pump applying

pressure to a diaphragm attached to the valve stem. Its

power unit is immersed in oil and hermetically sealed.

The HOV requires no adjustment or service. Stroke is

controlled by a travel limit switch and electromagnetic

relief valve. The unit rotates 360˚ for ease of installation.

Two-wire connection via 1/2 inch threaded conduit

terminal box is standard, and all units are equipped

with an auxiliary switch and dust shields.
