Abstract
This specification establishes the construction, coding, and performance requirements for self-contained, globe style, pressure-reducing valves used in water systems of shipboard installations that are limited to discharge pressure settings of 200 psig (1379 kPa) and below. The valves shall be either the pressurized spring chamber type (Type I) or unpressurized spring chamber type (Type II). They shall be tested for their conformance with hydrostatic proof, seat tightness, set pressure limits, and capacity.
Scope
1.1 This specification covers self-contained, globe style, pressure-reducing valves for use in water systems of shipboard installations. These valves are limited to discharge pressure settings of 200 psig (1379 kPa) and below.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
