KROM SCHRODER電磁閥VAS系列產品介紹
Valvario VAS系列常閉電磁閥可保護和控制向燃氣燃燒器和燃氣用具供應的空氣和氣體。適用于鋼鐵，玻璃和陶瓷行業(yè)各個領域的氣體控制和安全系統(tǒng)，也用于商業(yè)熱產生應用。
模塊化設計節(jié)省了空間和管道工作。主燃氣閥，先導閥，調節(jié)器和壓力開關均可以直接堆疊安裝，僅占用一個小的模塊空間。可變的安裝板可輕松減小輸入/輸出和法蘭尺寸。減少了在庫存中保留多種尺寸的需求。
關鍵規(guī)格
緊湊的設計和易于安裝
最大入口壓力為500 mbar（500 hPa / 7 psig）
無汞壓力開關具有測試端口和<25％的死區(qū)
帶內置視覺位置指示器的閉合開關證明
經過EC型式測試和認證，F(xiàn)M，CSA，UL和AGA認證
Valvario VAS series normally closed solenoid valves safeguard and control the air and gas supply to gas burners and gas appliances. For use in gas control and safety systems in all sectors of the iron, steel, glass and ceramics industries, also in commercial heat generation applications.
Modular design saves space and piping work. The main gas valve, pilot valve, regulator and pressure switch are all available for direct stack mounting for a single small modular footprint. Changeable mounting plates make it easy to reduce input/output and flange sizes. Reduces need to keep multiple sizes in inventory.
Key Specifications
Compact design and easy installation
Max inlet pressure of 500 mbar (500 hPa/7 psig)
Mercury-free pressure switch has test port and <25% deadband
Proof of closure switch with integral visual position indicator
EC type-tested and certified, FM, CSA, UL, and AGA approved
