5500球形截止閥
直接接觸,金屬對金屬座椅,使大多數(shù)關(guān)閉截止閥應(yīng)用的理想選擇。專為ASME鍋爐及壓力容器規(guī)范**節(jié)申請包括通風(fēng)口,排水渠,旁路系統(tǒng),儀表關(guān)閉,測量儀表的隔離,化學(xué)清洗系統(tǒng),控制閥隔離,輔助蒸汽管道,熱交換器,或任何可靠,無泄漏高溫下的性能/壓力條件下,是必需的。
Direct contact, metal-to-metal seating, make the globe valve ideal for most shut-off applications. Designed for ASME Boiler and Pressure Vessel Code, Section I applications including vents, drains, bypass systems, gauge shut-off, instrument isolation, chemical cleaning systems, control valve isolation, auxiliary steam lines, heat exchangers, or wherever reliable, leak-tight performance, under high temperature/pressure conditions, is required.
Features & Benefits:
- The 5500 has a fixed, repairable seat overlaid with Stellite or equal hardfacing.
- Available with threaded or socket weld end connections as standard.
- Valves are made using one-piece, die forged bodies.
- All internal surfaces are accurately machined to provide maximum performance.
- The disc is hardened, ground, and lapped to ensure leak free sealing over the valve’s full pressure/temperature range.
- A precision machined, integral backseat is standard.
- Both seats are designed for accurate, repeatable, seating alignment.
- Corrosion inhibited graphite packing and braided graphite filament anti-extrusion rings are standard.
- Standard body and bonnet materials are carbon steel (ASME SA105), alloy steel (ASME SA182 Gr. F11) and stainless steel (ASME SA182 Gr. F316) Trim for steel valves is 13% chrome 316 stainless steel valves have 316 trim.
- Also available in a variety of body and trim materials.
- A needle disc option is available.
- Code compliance with ASME/ANSI B16.34 and the ASME Boiler and Pressure Vessel Code, Section I.
