BURKERT 20127897 Type 6519 is a servo-assisted 5/2-way pneumatic solenoid valve. Together with Type 6518, they form a series of pilot-operated valves that can be used individually or on blocks. They operate without continuous air consumption and are used to control single- or double-acting actuators. The use of high-quality materials allows the valves to be used even in outdoor and chemically aggressive environments.

Circuit Functions

Symbol	Description
	Circuit function W (CF W) 5/2- or 3/2-way solenoid valve with changeover plate. 5/2-way: Pressurisation via port (1). Therefore one of the two ports (2) or (4) is under pressure. 3/2-way: Pressurisation via port (1), normally closed.
