通過(guò)閥座氣密性的短程或遠(yuǎn)程保護(hù)提供關(guān)閉。 Positive shutoff with visual or remote proof of seat tightness.
沒(méi)有產(chǎn)品污染的氣密性。 No product contamination absolute tightness.
雙閥座:合成橡膠 -金屬閥座加上金屬-金屬第二重密封。 Dual seating. Elastomer-to-metal seat plus metal-to-metal secondary seal.
防火:如果第二重合成橡膠閥座在火災(zāi)期間被損壞,則金屬-金屬閥座還可以保證氣密性。 Fire Safe. The metal-to-metal seat ensures tightness if the secondary elastomer seat is damaged during the fire.
PTFE閥座鑲嵌件:抗介質(zhì)的腐蝕,在工作溫度達(dá)到204°C時(shí),具有很好的抗磨能力。 PTFE seat insert resists corrosive media, has high abrasion resistance and operates up to +400°F (204°C).
配置410不銹鋼和密封焊接的閥座硬面。 Seat hardfaced with SS 410 and seal welded.
閥座用410不銹鋼進(jìn)行硬面,通過(guò)焊接裝配延長(zhǎng)使用壽命。將楔板從閥體上拆卸后,磨損的軟閥座鑲嵌件就很容易更換了。在更換閥座鑲嵌件之前,關(guān)閉流體,減輕壓力。 Seats are hardfaced with SS 410 and welded-in for lifetime service. A worn soft seat insert can easily be replaced after removal of wedge from the body. Shut off flow and relieve pressure before replacing the seat insert.
