The gate valve is used mainly as an on /off valve. This Gate Valve is also called as a Bi Directional Gate Valve. Mostly API 600/603 standard Gate valve contructions are bolted bonnet with rising spindle Pressure seal design bonnet design used for high pressure application from class 900
Cameron174; style gate valves allow low cost oil and gas valves to have an extended life by preventing trapping of pressure inside the valve cavity. API 6A gate valves 7 10 and 7 15 are forged to guarantee strength under maximum operation without flaw of cast.
5.Opening and closing torque is small, more open and close effort, because the gate valve opening and closing direction of flow and medium flow perpendicular to the valve, compared with the closing valve, gate valve opening and closing more effort.
API 6D Specification for Pipeline Valves (Plug, Gate, Ball and Check Valves) API 6D is the standard used for valves in pipeline service. API 6D has more stringent testing requirements compared to the API 600, 602, 608 or 609 design criteria.
API Valve Standards The American Petroleum Institute (API) , publishes over 600 standards for the design, manufacture, and testing of equipment in the oil natural gas industry. Below is a brief list identifying some of the available valve standards.
Today, most valve manufacturers strive for and achieve a zero closure test leakage rate during initial factory testing of their metal seated gate and globe valves. However, the predominant valve testing standard, API 598, Valve Inspection and Test, does have allowable leakage rates for these types of valves in sizes above NPS 2.
API 6A VALVE TYPES AND KEY FEATURES 1. BFE slab style gate is a simple one piece solid gate design, featuring metal to metal seal between gate and seats, so as to apply to the most severe and demanding service

API 623. Gate valves are governed by API 600 while check valve design is covered in API 594. Before the new standard API 623, it was common practice in the refining and petrochemical industries to see API 600 wall thicknesses referenced for a globe valve on a specification sheet even though API 600 only covers gate valves.
Api Pressure Seal (Gate Valve) It is a casted or forged full bore valve, with flexible wedge, sealed bonnet suitable for high pressures and temperatures, manufactured according API standard
MAJOR VALVE STANDARDS PETROCHEMICAL AND REFINING INDUSTRY API 600 Steel Valves Flanged Buttwelding Ends API 600 is the main steel gate valve speci cation. Valve design and construction criteria are speci ed, as well as materials and trim designations. An appendix covers information pertaining to pressure seal valves.

series of bolted bonnet steel gate valves for petroleum refinery and related applications where corrosion, erosion, and other service conditions would indicate a need for full port openings, heavy wall sections, and large stem diameters. This standard sets forth the requirements for the following gate valve features bolted bonnet,
API Standard 600, from the American Petroleum Institute, describes the criteria for valve design/construction and the material/trim designations for steel gate valves. The most recent version of this standard was published in January 2015, effective as of July 15, 2015.
Valve Standards API Std 520. Sizing, Selection, and Installation of Pressure relieving Devices in Refineries, Part I Sizing and Selection. This standard applies to the sizing and selection of pressure relief devices used in refineries and related industries for equipment that has a maximum allowable working pressure of 15 psig (103 kPag) or greater.
API 6FC Fire Test for Valve with Automatic Backseats. The standard covers the requirements for testing and evaluating the performance of API Spec 6A and Spec 6D valves with automatic backseats when exposed to specifically defined fire conditions. API 600 Bolted Bonnet Steel Gate Valves for Petroleum and Natural Gas.
API 598 Valve Inspection and Testing. The standard covers inspection, supplementary examination, and pressure test requirements for both resilient seated and metal to metal seated gate valve, globe valve, plug valve, ball valve, check valve, and butterfly valves.
(d) Each valve must be both hydrostatically shell tested and hydrostatically seat tested without leakage to at least the requirements set forth in Section 11 of API Standard 6D (incorporated by reference, see 167;195.3). (e) Each valve other than a check valve must be equipped with a means for
Valve standards from API the American Petroleum Institute. API SPEC 6D Specification for Pipeline Valves. API Specification 6D is an adoption of ISO 14313 1999, Petroleum and Natural Gas Industries Pipeline Transportation Systems Pipeline Valves. This International Standard specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball
API Standard 6D, from the American Petroleum Institute, provides specifications for pipeline valves. Scope. API 6D covers the design, manufacture, testing, and documentation for pipeline ball, check, gate, and plug valves for pressure ratings up to ASME class 2500.
Gate Valve are not used for modulation as the high velocity through a partially open valve may result in erosive damage to the wedge and seats. Walworth offers this product line manufactured in accordance with API 602, and ANSI Class 800, 1500 and 2500 for socket weld, threaded and combined ends.
Data necessary for the order (standard API 600 is applied) type number, nominal diameter, pressure class, design The yoke gate valve can be assembled in any position into the pipeline. The gate valves are supplied in different material variants. The construction of steel gate valves of MSA corresponds to API 600 and BS 1414.
For many API rising stem valve design standards (such as API 600, 602, 603, and 623), API 624 has been or may be written into the standard as a requirement for the valve design. This means the valve will not be considered conformant to the respected standard unless the design has successfully passed the requirements of API 624.
3. API temperature ratings X and Y require working pressure of valve to be de rated as per API 6A annex G. 4. Nitriding is standard on all gates and seat. Hardfacing with tungsten carbide, Hf6 or other techniques are available.. 5.
This standard specifies the requirements for corrosion resistant bolted bonnet gate valves meeting the requirements of Standard Class, ASME B16.34 and having full port openings for use in process piping applications.
