It also covers both lubricated and nonlubricated valves that have two-way coaxial ports, and includes requirements for valves fitted with internal body, plug, or port linings or applied hard facings on the body, body ports, plug, or plug port.Д«olted Bonnet Steel Gate Valves for Petroleum and Natural Gas Industries - Modified National Adoption of ISO 10434:1998.Д¬ompact Steel Gate Valves - Flanged, Threaded, Welding, and Extended-Body Ends. Valve bodies conforming to ASME B16.34 may have flanged end and one butt-welding end. A purchase specification that covers requirements for metal plug valves with flanged or butt-welding ends, and ductile iron plug valves with flanged ends, in sizes NPS 1 through NPS 24, which correspond to nominal pipe sizes in ASME B36.10M. Metal Plug Valves - Flanged, Threaded and Welding Ends. Pertains to inspection by the purchaser and to any supplementary examinations the purchaser may require at the valve manufacturer's plant. The standard covers inspection, supplementary examination, and pressure test requirements for both resilient-seated and metal-to-metal seated gate, globe, plug, ball, check, and butterfly valves. API Standard 594 covers design, material, face-to-face dimensions, pressure-temperature ratings, and examination, inspection, and test requirements for two types of check valves. Describes methods of determining the seat tightness of metal- and soft-seated pressure relief valves, including those of conventional, bellows, and pilot-operated designs.Д¬heck Valves: Flanged, Lug, Wafer and Butt-welding. Seat Tightness of Pressure Relief Valves R(2002). Basic requirements are given for direct spring-loaded pressure relief valves and pilot-operated pressure relief valves as follows: orifice designation and area valve size and pressure rating, inlet and outlet materials pressure-temperature limits and center-to-face dimensions, inlet and outlet. The standard is a purchase specification for flanged steel pressure relief valves.

This International Standard specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball, check, gate and plug valves for application in pipeline systems.ДЇlanged Steel Pressure Relief Valves. API Specification 6D is an adoption of ISO 14313: 1999, Petroleum and Natural Gas Industries-Pipeline Transportation Systems-Pipeline Valves. Valve standards from API - the American Petroleum Institute:
