Description
The ASCO Series HOV1B are bronze-bodied safety valves electro-hydraulically operated to provide reliable on-off control of fuel oil.
The valves´ spring-loaded, stem-guided PTFE seat opens within 9 seconds of power application and closes within 1 second of power interruption. The valves are agency-approved for fuel oil safety shutoff.
The HOV1B Series consist of a flexible two-piece actuator and the valve body design that is ideal for OEMs who want both actuator and body as a set, and for end users and distributors who want to minimize inventory by mixing/matching separate actuators and valve bodies.
Features- Self-contained, hermetically sealed, pull-type electrohydraulic actuator has motor/pump unit immersed in oil, reducing wear and enhancing reliability
 - Rugged construction and broad ambient temperature range (-40° to 150° F) permit use in challenging environments
 - Type 1 General Purpose enclosure standard, optional Type 4, 7 Watertight and Explosion-proof enclosure for hazardous locations
 - H118 Series offers 1-inch to 3-inch NPT and 4-inch flange end connections flow range from Cv 124 to 510 and operating pressures from 4 psi to 20 psi
 - Visual indication of valve open & closed position is standard
