This simplifies the trim and allows the actuator to apply maximum direct force to the seat, achieving tighter shutoff for high-pressure steam and hydrocarbons.<\/p>\n<p data-path-to-node=\"4\">Severe Service Angle Body: The angle configuration is specifically designed to manage high-pressure drops. By directing the flow in a 90-degree turn, the valve can help reduce the erosive effects of high-velocity fluids on the downstream piping and valve body.<\/p>\n<p data-path-to-node=\"5\">Rugged Cage Guiding: The valve plug is supported by a heavy-duty cage that provides continuous guiding throughout the stroke. This stability is critical in high-pressure applications to prevent plug oscillation, vibration, and mechanical noise.<\/p>\n<p data-path-to-node=\"6\">Intermediate Pressure Ratings: When supplied with weld-end fittings, the HPAS can be rated beyond standard ASME Class 1500. These intermediate ratings allow the valve to operate safely in modern high-temperature, high-pressure power cycles that exceed standard ANSI classifications.<\/p>\n<p data-path-to-node=\"7\">Premium Spiral-Wound Gaskets: To ensure a reliable pressure boundary, the HPAS uses high-grade spiral-wound gaskets (Alloy 600 or X750 with Graphite). These materials are chosen for their resilience against the thermal cycling and extreme pressures typical of utility and refinery service.<\/p>\n<p data-path-to-node=\"8\"><span class=\"citation-4993 citation-end-4993\">Standard Hardened Trim: To resist erosion and wear, the cage and valve plug are manufactured from hardened materials as standard.<\/span> This ensures a long service life and maintains control precision even when handling abrasive or high-velocity media.<\/p>\n<h3 data-path-to-node=\"9\">Matriks Prestasi Teknikal<\/h3>\n<table data-path-to-node=\"10\">\n<thead>\n<tr>\n<td><strong>Ciri<\/strong><\/td>\n<td><strong>Butiran<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-path-to-node=\"10,1,0,0\">Gaya Injap<\/span><\/td>\n<td><span data-path-to-node=\"10,1,1,0\">Badan Sudut (Port Tunggal)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"10,2,0,0\">Tindakan Palam<\/span><\/td>\n<td><span data-path-to-node=\"10,2,1,0\">Tidak Seimbang (Tekan ke bawah untuk menutup)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"10,3,0,0\">Membimbing<\/span><\/td>\n<td><span data-path-to-node=\"10,3,1,0\">Rugged Cage Guided<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"10,4,0,0\">Kelas Tekanan<\/span><\/td>\n<td><span data-path-to-node=\"10,4,1,0\">CL900, CL1500, and Intermediate Ratings<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"10,5,0,0\">Gaskets<\/span><\/td>\n<td><span data-path-to-node=\"10,5,1,0\">Alloy 600\/Graphite or Alloy X750\/Graphite<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"10,6,0,0\">Pilihan Aliran Rendah<\/span><\/td>\n<td><span data-path-to-node=\"10,6,1,0\">Micro-Flute and Micro-Form valve plugs<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h4 data-path-to-node=\"11\">Aplikasi Utama<\/h4>\n<p data-path-to-node=\"12\">High-Pressure Drains and Vents: Reliable isolation and throttling for boiler and turbine drains.<\/p>\n<p data-path-to-node=\"12\">Hydrocarbon Production: Managing wellhead letdown and high-pressure gas processing.<\/p>\n<p data-path-to-node=\"12\">Chemical Synthesis: Precise control in high-pressure reactor loops where shutoff is critical.<\/p>\n<p data-path-to-node=\"12\">Power Plant Utilities: Controlling high-pressure steam bypass and auxiliary systems.<\/p>","protected":false},"excerpt":{"rendered":"<p>The Fisher HPAS is a specialized angle-body control valve within the HP Series, featuring an unbalanced plug design.
