進口高溫電磁閥，High temperature solenoid valve，是指閥體以及密封采用耐高溫的材料，采用耐溫線圈、不易燒毀、精密鑄造、外觀精美的電磁閥，適用于中高溫熱水、導熱油、高溫蒸汽、飽和蒸汽及過熱蒸汽等管路的自動控制,zui高耐溫達550度；廣泛應用于科研、服裝設備、石油化工、生物制藥、暖通空調、電鍍涂裝、干燥設備、橡塑機械、食品飲料、造紙、印染及電力礦業等行業。
進口高溫電磁閥產品特點：
進口高溫電磁閥閥芯均為不銹鋼活塞式，活塞環用特殊耐溫、耐磨材料制作；活塞與金屬閥腔不產生直接摩擦，閥體安裝方向無限制；特制線圈，并采用散熱的結構方式，因此不易燒毀；長時間停止動作重新啟動，動作同樣靈敏；zui低啟動壓力0.2MPa。
德國托克TOK品牌：進口高溫高壓電磁閥應用范圍廣泛應用在航天、船舶重工、石油化工、給排水、消防設備、食品醫療設備、清洗設備、景觀噴灌、加濕設備、液壓設備、測試設備、水廠等,工作壓力在6.4---100MPa的管道系統中。
進口高溫高壓電磁閥產品特點：
閥芯均為不銹鋼活塞式，活塞環不會被介質中的雜質卡死，動密封性能高,壽命長；活塞與金屬閥腔不產生直接摩擦，閥體安裝向無限制；專制線圈，不易燒毀；長時間停止動作重新啟動，動作同樣靈敏；zui低啟動工作壓力0.5MPa。
主要技術參數：

工作原理：
常閉：當線圈通電時，先導閥芯吸合，先導孔打開，閥上腔卸壓，活塞靠下腔介質壓力推動，電磁閥打開；當線圈斷電時，先導閥芯靠彈簧復位，先導孔關閉，閥腔由活塞節流孔增壓和復位彈簧的推力，電磁閥關閉。

規格尺寸：

注：出口端壓力大于進口端壓力，介質會反向導通。可安裝止回閥或訂制自帶止回功能的閥。
Applications: 
Widely used in aerospace, shipbuilding Heavy Industry, petrochemical, water, fire fighting equipment, food and medical equipment, cleaning equipment, landscape irrigation, humidification equipment, hydraulic equipment, testing equipment, water plant, the work pressure in the pipeline 6.4 --- 100MPa system.
Features: 
Spool is stainless steel piston and piston rings will not be stuck impurities in the medium, dynamic sealing performance and long life; piston valve chamber with the metal does not produce direct friction, the valve installed to the limit; authoritarian coil, easily burned ; for a long time to restart the stopped action, action as sensitive; minimum start working pressure 0.5MPa.
Main technical parameters:

How it works: 
NC: When the coil is energized, the pilot spool pull the pilot hole to open, pressure relief valve on the chamber, the piston on the lower chamber medium pressure to promote, the electromagnetic valve is opened; When the coil power, the pilot valve by the spring return, pilot hole closed throttle valve chamber pressurized by the piston return spring and thrust, the electromagnetic valve is closed. 
Normally Open: When the coil is energized, the pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed. When the coil power, the pilot valve by the spring return, pilot hole open, pressure relief valve on the chamber, the piston on the lower chamber medium pressure to promote the solenoid valve open.
Size:

Note: The outlet pressure is greater than the inlet pressure, the media will pass anti-wizard. Can be installed or custom built non-return valve function of the valve.
