Electric Solenoid Valves and Air Horn Manufactured and Submitted by Clark Cooper Company, for Submarines SS-176 to SS-178
Abstract
The object of this test was to determine whether the electrically operated valve and air horn, submitted under reference has been modified in accordance with recommendations. Type approval tests were also conducted on an electrically operated valve, Type N, embodying later modifications. Each of the valves was connected to a horn and tested for operation at various air pressures while being supplied with voltages ranging from 10 percent above to 10 percent below its rating (115 volts D.C.) Part of the test was conducted at ambient temperature of 40 deg C and the remainder at approximately 26 deg C. Under these conditions the valves were also tested for operation when inclined 30 degrees from normal in ever-J direction. It is recommended that the valve submitted under reference be approved for the Naval Service, subject to correction of defect causing leak and correction of the adhering of the armature to the stationary armature. This valve is considered far more satisfactory in view of its better performance throughout the test. It is further recommended that the air horn be approved.
