1. PURPOSE / OBJECTIVE i The purpose of this calculation is to verify the adequacy of Crane 36"-125 lb Ferrosteel Wedge Gate Valve for the postulated seismic loads.

Valve Tag Numbers: OWS015A,B,C,D,E,F .,

2. METHODOLOGY AND ACCEPTANCE CRITERIA These manual valves are required to maintain their pressure and structural integrity during and after a seismic event. They are also required to maintain their open position in case of a seismic event. Maximum stresses in the valve body due to piping end loads will be compared to the valve body material strength to verify pressure and structural integrity. To show that the valves stay open during a seismic event, the threaded connection between the stem and the disc (weak link) will be evaluated for the combined dead weight and seismic loads. Evaluation of yoke legs and yoke pad '

bolts will also be performed for seismic loads.

Material tensile strength: 31000 psi (Ref. 3)

Since the stress due to pressure and piping end loads is small (1.44% of material tensile strength), the subject valves are adequate for pressure integrity.

Check bolted flanae connection (valve to oice)

Per Reference 1 (valve drawing), the flange dimensions and drilling conform to ANSI B16.1-125 lb. The adequacy of this bolted flange is verified by comparing the total
