2-Way Oil Shutoff Valve
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.
