ASCO Proportional Control Motor Piston Valve
Made in Japan
Manufacturer: ASCO JAPAN Co.LTD.
This is a motor type proportional control piston valve that does not require an air pressure source. Since no air pressure source is required, a compact layout is possible.
Piping size 3/8, 1/2, 3/4
Air, gas Class 1 & 2
Water, oil, liquid Class 1 & 2
Steam (up to 145°C)
Features
No air pressure source required
Also supports high temperature steam (up to 145℃)
Can be used in vacuum conditions up to 10 -2 Bar
Two types: On/Off type and proportional control
LED lamp indicates valve open/close status
Open/close signals can also be sent to a PLC
