ASTM F1370-92(2011)

Standard Specification for Pressure-Reducing Valves for Water Systems, Shipboard

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.
1.3 The following precautionary caveat pertains only to the tests portion, Section 8, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
