ASCO™ HOV1B Hydramotor Safety Valves
Hydramotor Valves HOV1B ASCO
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. The HOV 1B Series are suitable for boilers/burners, ovens/furnaces, kilns/incinerators, and heating equipment.
