    Parker 減壓閥
    Parker Pressure Relief Valves
    高壓安全閥 - MAR系列Relief Valves,High Pressure - MAR Series

    派克MAR系列安全閥(硬閥座式和軟閥座式)提供了穩定的排放氣體或液體的應用,工作壓力可達從1,500 psi(103bar)到75,000 psi(5171 bar)。 Parker's MAR Series (Hard and Soft Seat) relief valves provide reliable venting of gases or liquids for set pressures from 1,500 PSI (103 BAR) minimum to 75,000 PSI (5171 bar).

     

     

    派克MAR系列安全閥提供系統承壓高達20000 psi(1378 bar)的兩種不同的設計,一個是硬閥座式安全閥和另一種是軟閥座式。派克的MARA系列(硬閥座)安全閥提供了穩定的排放氣體或液體的應用,工作壓力為從3000 psi(206.8bar)到20000 psi(1378 bar)。型號的標準溫度范圍是-423°F到400°F(-252°C ~ 204°C)。高溫選項750°F(399°C)也是可以選用的。這些精密閥門是為高壓氣體系統、超低溫系統、石化等系統應用設計的。 Parker's MAR Series Relief Valves offer two distinct designs for systems up to 20,000 PSI (1378 BAR). One is a hard seat relief valve and the other is a soft seat relief valve. Parker's MARA Series (Hard Seat) relief valves provide reliable venting of gases or liquids for set pressures from 3,000 psi (206.8 bar) minimum to 20,000 psi (1378 bar). The standard temperature range for all models is -423oF to 400oF (-252oC to 204oC). A high temperature option to 750oF (399oC) is also available. These precision valves are designed for pressure gas systems, cryogenic systems, petrochemical applications and other special systems.

    這些精密閥門是為高壓氣體系統設計使用,其中無泄漏是關鍵。他們不推薦用于液氮或液態二氧化碳,產生的氣體會在低溫下泄放。派克安全閥門的設計,是一款比例泄放模式,也就是隨著壓力越來越大,泄放量也按比例的隨之增加。因此,我們是不建議在設定壓力值處發生立即的全閥開口的流量泄放的應用(如分解反應、聚合反應產生等),安全閥的全流量泄放將發生在超過設定壓力10%的時候。 These precision valves are designed for pressure gas systems, where zero leakage is critical. They are not recommended for liquid nitrogen or liquid carbon dioxide, which produce gas at cryogenic temperatures upon relief. Relief valves are designed to open proportionally to increasing pressure. Therefore, they are not recommended for applications requiring immediate full valve flow at set pressure (such as decompositions, polymerizations, etc.). Full flow of relief valve is defined at 10% over set pressure.

    派克的MARSA系列(軟閥座)安全閥提供了穩定的排放氣體應用,工作壓力為從1500 psi(103bar)到20000 psi(1378 bar),工作溫度范圍為32°F(0°C)400°F(204°F)。軟閥座安全閥提供了氣密密封(使用氣泡法測試),可重復彈起開啟,及有效復位。此外,軟閥座安全閥提供比金屬閥座較高的循環使用壽命。 Parker's MARSA Series (Soft Seat) relief valves utilize a soft seat design for reliable venting of gases at set pressures from 1,500 psi (103 bar) to 20,000 psi (1378 bar). The operating temperature range is 32oF (0oC) to 400oF (204oF). The soft seat design provides bubble tight sealing, repeatable pop-off, and reseat. Additionally, soft seat valves provide a higher cycle life than metal seat relief valves.
