Datasheet

The Asco H0V1B302T171 VALVE & Actuator 120V 1/2″

The HOV1(B) is a push-type, self-contained, 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 electrohydraulic actuator can be purchased separately, and consists of a pump applying pressure to a piston pushing the valve stem. Its power unit is immersed in oil and sealed. The HOV1(B) assembly, which consists of an actuator and the valve body mounted together by users, requires no adjustment or service. Stroke is controlled by a travel limit switch and electromagnetic relief valve. The unit rotates 360º for ease of installation. Two-wire connection via 1/2 inch threaded conduit terminal box is standard. The HOV1(B) comes standard with valve seal overtravel and electrical interlock proof of closure switch. An optional auxiliary switch is also available
