They are engineered strictly as on-off isolation devices and must never serve as flow control or throttling valves.<\/p>\n<p>Operating a gate valve in a partially open position causes high-velocity fluid to strike the unsupported wedge edge. This induces destructive chatter, wire drawing across seating faces, and localized cavitation that ruins tight shutoff capabilities.<\/p>\n<div class=\"warning-box\">\n<p>Partially opening a full bore gate valve accelerates erosion on both the wedge disc and body seat rings. Always cycle the valve to its fully open or fully closed position to protect the machined sealing faces.<\/p>\n<\/div>\n<p>Additionally, multi-turn threaded stems require substantial vertical clearance above the pipeline for rising stem travel. Operators must account for handwheel access and overhead pipe rack clearances during structural piping layout planning.<\/p>\n<\/section>\n<section id=\"installation-and-maintenance-practices\">\n<h2><span class=\"ez-toc-section\" id=\"Pipeline_Installation_and_Inspection_Guidelines\"><\/span>Pipeline Installation and Inspection Guidelines<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Proper installation and routine inspection help preserve valve service life and maintain positive shutoff integrity. Piping crews should flush lines thoroughly before bolting or welding valves into place to eliminate slag, scale, and foreign debris.<\/p>\n<p>Tightening flange fasteners using cross-pattern torque procedures prevents uneven stress on the valve neck and seat rings. For welded-end valves, following welding procedure specifications protects the heat-affected zone near critical seat rings.<\/p>\n<ol class=\"list-numbers\">\n<li>Clean connecting pipe ends and remove foreign particles before positioning the valve.<\/li>\n<li>Support adjacent piping adequately to prevent heavy bending stresses on the valve body.<\/li>\n<li>Cycle the handwheel through a complete stroke before introducing line pressure to verify smooth stem travel.<\/li>\n<li>Perform hydrostatic and low-pressure air seat tests in accordance with API 598 protocols.<\/li>\n<li>Inspect stem packing periodically and adjust gland bolting evenly to prevent packing leaks.<\/li>\n<\/ol>\n<p>Regular maintenance involves greasing stem threads with compatible lubricants and verifying that bonnet bolting remains properly torqued. Routine inspections reduce the likelihood of stem binding and keep the valve ready for isolation cycles.<\/p>\n<div class=\"img-container\">\n<div class=\"image-embed\" data-image=\"%7B%22src%22%3A%22https%3A%2F%2Fstorage.googleapis.com%2F48877118-7272-4a4d-b302-0465d8aa4548%2F7c0162ef-88b5-4cf7-9ba9-cc48ad7031d3%2F5341d9ee-1082-48ea-a4e4-c12697436283.jpg%22%2C%22title%22%3A%22Technician%20inspecting%20valve%20packing%20gland%20bolts%20with%20calibrated%20torque%20wrench%22%2C%22method%22%3A%22text-to-image%22%2C%22generator%22%3A%222%22%2C%22date%22%3A1791721376143%7D\">\n<div class=\"_Media_1itgw_1 _ImageEmbed_1itgw_28\">\n<div class=\"_Buttons_1itgw_5\" contenteditable=\"false\" data-media=\"true\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<section>\n<h2><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Preguntas frecuentes<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div class=\"faq-item\">\n<h3 class=\"faq-question\"><span class=\"ez-toc-section\" id=\"Can_a_full_bore_gate_valve_accommodate_pipeline_scraper_pigs\"><\/span>Can a full bore gate valve accommodate pipeline scraper pigs?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"faq-answer\">\n<p>Yes, full bore gate valves feature an internal diameter that matches the connecting pipe, allowing mechanical pigs and cleaning tools to pass through without obstruction. The fully retracted wedge clears the bore completely.<\/p>\n<\/div>\n<\/div>\n<div class=\"faq-item\">\n<h3 class=\"faq-question\"><span class=\"ez-toc-section\" id=\"Why_does_a_full_bore_gate_valve_produce_minimal_pressure_loss\"><\/span>Why does a full bore gate valve produce minimal pressure loss?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"faq-answer\">\n<p>Because the fully opened port provides a straight, full-diameter cylindrical path that eliminates flow restriction. This straight-through design prevents the turbulence and head loss typical of tortuous valve bodies.<\/p>\n<\/div>\n<\/div>\n<div class=\"faq-item\">\n<h3 class=\"faq-question\"><span class=\"ez-toc-section\" id=\"What_is_the_difference_between_a_flexible_wedge_and_a_solid_wedge\"><\/span>What is the difference between a flexible wedge and a solid wedge?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"faq-answer\">\n<p>A flexible wedge features a machined circumferential groove that allows the sealing faces to flex slightly under pipeline thermal expansion. A solid wedge is a rigid single-piece casting or forging used primarily in smaller sizes and uniform temperature service.<\/p>\n<\/div>\n<\/div>\n<div class=\"faq-item\">\n<h3 class=\"faq-question\"><span class=\"ez-toc-section\" id=\"Why_should_a_full_bore_gate_valve_never_be_used_for_throttling\"><\/span>Why should a full bore gate valve never be used for throttling?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"faq-answer\">\n<p>Throttling causes high-velocity fluid to erode the bottom edge of the partially exposed wedge and seat faces. The resulting flow vibration and cavitation cause seat leakage and compromise shutoff reliability.<\/p>\n<\/div>\n<\/div>\n<div class=\"faq-item\">\n<h3 class=\"faq-question\"><span class=\"ez-toc-section\" id=\"How_does_API_600_differ_from_API_602_for_gate_valves\"><\/span>How does API 600 differ from API 602 for gate valves?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"faq-answer\">\n<p>API 600 governs heavy-duty bolted bonnet cast steel gate valves commonly used in larger process pipelines.
