MIL-V-24740
VALVE, SAFETY: BOILER, REMOTE PILOT OPERATED, FOR SHIPBOARD USE
Organization:
NAVY - SH - Naval Sea Systems Command (Ship Systems)
Year: 1990
Abstract: This specification covers a high-performance boiler safety valve with a remote, hydraulic, non-steam flow pilot assembly, for steam drum and superheater service at working pressures of 600 and 1500 pounds per square inch (lb/in2). Intended Use: The boiler safety valves covered by this specification are intended for installation at the superheater outlet or on the steam drum with the pilot assembly located remotely from the boiler and unloader valve. This provides features for ease of maintenance, shipboard level repair capability for satisfactory replacement of moving parts, high service time to leakage rate ratio, simplified ease of setting features, cold pilot setting ability, and a built-in gagging feature. The valve uses boiler fluid as the working fluid and operates completely without any auxiliary means of power such as air or electricity.
