A 3-position valve that can be set to fully closed, fully open, and intermediate opening.
The 3-position valve is a process valve with a unique Burkert structure that can achieve full closure/full opening as well as intermediate opening levels.
Introducing Bürkert's unique structure new lineup of 3-position valves that achieve flow control solely through the On/Off of instrument air. ○ Achieves full open/close as well as intermediate opening (flow control) on its own! ○ Enables simple flow control without electrical equipment! (The valve's full close/open and intermediate opening are controlled by the On/Off of instrument air) ○ Achieves high durability just like Bürkert's previous On/Off valves! For example, you can utilize it in the following scenarios... ● Temperature control → When you want to enhance control beyond traditional ON/OFF control (intermittent control), improving control is possible by utilizing intermediate opening. ● Filler (diaphragm) → It is possible to suppress the flow rate at the start and end of filling with intermediate opening, while filling in between can be done at maximum flow rate (full open).
basic information
**Features** ○ Capable of holding intermediate opening in addition to fully closed/fully open → Intermediate opening can be set/adjusted as desired using the adjustment nut on the actuator's top surface. ○ High durability with a structure equivalent to conventional models → Achieves high durability comparable to Type 2000. ○ Easily introducible into existing processes → Lightweight and can be easily installed without support. ○ Operable with simple controls → The twin-cylinder structure allows for operation of fully open, intermediate opening, and fully closed positions with just the On/Off of two systems of instrument air.
