2W series pressure-free starting electromagnetic valve
Special recommendation：wide usage、flat price, and fine quality

●（Usage）
　　This serial electromagnetic valve adopts hot forge shaping; the inside is made by stainless steel. Widely applied in the switch and cut of pipelines with which the mediums are water, low-pressure steam, compressed air, and oil, etc; Implements automotive control.

●（Structure characteristics）
■The electromagnetism straightly move diaphragm type operating structure
■The valve body adopts brass hot forge shaping, small, and the appearance is beautiful
■The diaphragm slice is made by temperature-bearing material，especially suitable for the use in low-pressure steam pipe work
■The diaphragm adopts silica gel, and can be used in food processing industry
■Pattern：Always shut down and always switch open
