應用范圍：
它廣泛應用于冶金、石化、制藥、煙草、橡膠、食品醫療、城建環保、給排水、采暖空調、消防安全、科研、景觀噴灌、節能產業等各個領域。

產品特點：
閥芯為雙活塞閥芯，壽命長；換向和分流迅速；專制線圈不易燒毀；在真空負壓、零壓時都能正常工作。閥體安裝方向無限制。

主要技術參數：

工作原理：
一進一出：常閉式：當線圈通電時，2通向1，1與3關閉。當線圈斷電時，2與1關閉，1通向3。
　　　　　常開式：當線圈通電時，3與1關閉，1通向2。當線圈斷電時，3通向1，1與2關閉。
一進二出：當線圈通電時，1通向2，1與3關閉。當線圈斷電時，1與2關閉，1通向3。
二進一出：當線圈通電時，2通向1，3與1關閉。當線圈斷電時，2與1關閉，3通向1

規格尺寸：

注：二進一出工作原理的閥兩進口端壓力不相等時，需加止回閥。

Applications:
It is widely used in metallurgy, petrochemical, pharmaceutical, tobacco, rubber, food and medical care, urban construction and environmental protection, plumbing, heating and air conditioning, fire safety, scientific research, landscape irrigation, energy industry and other fields.

Features:
A dual piston valve spool, long life; and diversion to the rapid change; authoritarian coil easily burned; in a vacuum, negative pressure, zero pressure can work. Valve mounting direction unlimited.

Main technical parameters:

How it works:
Entering and exiting: Normally closed: When the coil is energized, the two leads 1,1 and 3 closed. When the coil power, the 2 and 1 off, 1 leads to 3.
Always open: When the coil is energized, 3 and 1 off, 1 leading to 2. When the coil power, the 3 leading to 1,1 and 2 closed.
One into two: When the coil is energized, 1 leading to 2,1 and 3 closed. When the coil power, the 1 and 2 closed, 1 leads to 3.
Binary one: When the coil is energized, the two leading to 1,3 and 1 closed. When the coil power, the 2 and 1 off, 3 leading to a

Size:

Note: The working principle of a binary valve inlet pressure is not equal two, the need to add check valves.
