一、結構及用途 Structure and purpose

        該閥是以電磁閥為導閥的水力操作閥門，用于管路系統中的自動控制，根據電信號遙控開啟和關閉管路系統，實現遠程操作控制反應準確快速，閥門關閉速度可調，關閉平穩而不產生壓力波動，電磁閥可采用交流電220V或直流電24V并可根據場合選用常開或常閉型。該閥體積小、重量輕、維修簡單、使用方便、安全可靠、使用壽命長。可代替閘閥和蝶閥用于大型電動操作系統。

A hydraulic operated valve taking a solenoid valve as the pilot valve．used in a pipeline system for automatic control and to remotely control open-close of the system upon an electric signal，accurate and quick response in the execution of remote operation and control，adjustable valve close speed，stably closed without any pressure fluctuation．The solenoid valve can use either AC220V or DC24V power and is available with normal open or close type．This valve features a small volume，light weight，easy repair and use，safety and reliability，long duration and can replace both gate and butterfly valves for use in a large electric operation system.
