Product Description

Summary
The air‑lock valve JF400/430 is a device that promptly monitors pressure when the supply pressure falls below the set value and automatically shuts off the flow path.
Features
① Small size, lightweight, requires no additional mounting bracket, and can be connected to metal piping.
②It also responds sensitively to minute pressure differences below 0.1 kgf/cm².
③ Epoxy resin coating is used, offering excellent corrosion resistance.
④ Limit switches and indicators may be added to monitor the on/off status of the YT–400.
