General
We have been offering a complete range of pneumatic logic valves for many years. These include the valve functions “OR”, “AND”, “YES”, “NOT” and “Memory”. With these logic valves, simple pneumatic basic circuits can be realized easily and reliably.
Logic valve OR
The logic valve OR (Or) has pressure at output A if pressure is present at one of the two inputs or at both inputs.
Logic valve AND
The logic valve AND (and) has pressure at output A if pressure is present at both inputs a and b.
Logic valve YES
The logic valve YES (yes, identity) has pressure at output A when compressed air is present at input a and control connection x is also pressurized.
Logic valve NOT
The logic valve NOT (no, negation) has pressure at output A if compressed air is present at input a and control connection x is NOT pressurized.
Logic valve MEMORY
The logic valve MEMORY is a pneumatically controlled 5/2-way pulse valve, i.e. the valve remains in the current switching position until a new control signal switches to the other output. - It remembers the switching status until it is switched over by another control signal.
Output x has pressure when pressure is present at input p and control input x1 was last actuated. Output x(transverse) has pressure if pressure is present at input p and control input x0 was actuated last.
Logic valves from SFS-Fluidsysteme
In addition to an optimum price/performance ratio, our logic valves impress with their compact design, long service life and simple mounting by snapping onto the top-hat rail or alternatively with 2 mounting holes. The logic valves offer a plug-in connection for 4 mm hoses. The switching status can be read from the outside at any time using a colored pressure indicator pin.
As the logic valves operate purely pneumatically and do not require a power connection, they do not fall under the ATEX directive and can therefore also be used in potentially explosive areas without any problems.
