Torque Seated Triple Offset Butterfly Valves for refining, industrial, mining, and severe service applications | Series 78

Basic Design Standards

a.In addition to the specific industry standard noted herein as a minimum the valve design will meet the applicable requirements of the following industry standards I.ASME B16.34 including the pressure/temperature ratings for valve body, disc and bottom cap materials valve body minimum wall dimensions: nondestructive examination and markings. II.API STD 609 including basic design requirements applicable to category B III.API STD 598 including hydrostatic shell and hydrostatic and pneumatic seat testing. IV.MSS-SP-55 for visual inspection of cast valve body, disc and bottom cap. V.ASME B16.5 for mating pipe flange dimensions for valve sizes 3'' through 24'' Class 150& 300. VI.ASME B16.47 for series B mating pipe flange dimensions for valve sizes 26'' and larger Class 150 & 300 VII.ISO-5752 Flange Dimension VIII.Fire Tested and Certified to API 607, 6th Edition

Face TO Face Dimensions

a.Lug Design-nominal dimension listed in API STD 609 Table 2 for category B valves b.Wafer Design-nominal dimension listed in API STD 609 Table 2 for category B valves c.Flanged(double flanged, short pattern)-nominal dimension in API STD 609,Table C and ISO 5752 basic Series 13. d.Flanged(double flanged, long pattern)-nominal dimension in API STD 609,Table B and to Gate valve Dimensions per ANSI 16.10 table A1 Column 7 for 150# valves and Table A2 Column 10 for 300# valves

Seat Leakage Performance

A.Each valve exhibits the seat leakage performance as follows: I.Perferred side(pressure entering the valve on the shaft side of the shut disc)-zero seat leakage at the low pressure and high pressure test. Each valve shall have an arrow on the external valve body indicating the direction of high pressure. II.Non preferred side(pressure entering the valve with the shaft on the opposite side of the shut disc) only zero seat leakage at the low pressure closure test per API 598.HIgh pressure closure test on application III.Shell Test-Each unpainted valve assembly is hydrostatically sheel tested in accordance with the applicable test requirements stated in API STD 598. a.The Fluid-Filtered clean water(may contain a water-soluble oil or rust inhibitor).When testing austenitic Stainless steel valves the chloride content does not exceed 100 parts permilion. b.Test Leakage-No visually detectable leakage through the pressure boundary walls.Leakage through c.the adjustable shaft packing shall not be cause for rejection.however the packing must be able prevent any leakage at a test pressure equal to the 100°F(38°C)valve body rating d.Standard Production Seat leakage test-Each production valve assembly,unless otherwise stated on the purchase order,shall be seat tested in accordance with the requirements listed in API STD 598

The Series 78 can be fully automated by either pneumatic or electric actuators though out its size range. Flow Line’s extensive automation capabilities are due to the fact that we developed our actuator and accessories from the ground up. Our automation products were design with the torques needed to be able to automate all Flow Line valves. Because all Flow Line valves are to the latest ISO 5211 standards, there is no need for brackets and couplers when using Flow Line actuators on Flow Line valves. We give you a single source for quality automation packages.
