DIAMOND POWER SPECIALTY CORPORATION 1-1/2IN. 1500 PSI, TYPE I, CLASS 2, STYLE A BOILER BLOWDOWN ANGLE VALVE.
Abstract
A 1-1/2in. 1500 PSI, Type I, Class 2, Style A, boiler blowdown angle valve was evaluated to determine compliance with the requirements of Military Specification MIL-V-17737A(SHIPS) of 10 Feb 1956 and Amendment 1 of Apr 1956. The subject valve exhibited excessive operating torque, seat and packing leakage, and galling of the disc holding surfaces at contact with both ends of the stem recess, and was therefore considered unsuitable for use in shipboard boiler blowdown service.
