KNORR PNEUMATIC TKVG-5 I/55439

Knorr Pneumatic 5/2-Way Air Pilot Valve

Description

This is a TKVG-5 pneumatic valve from Knorr Pneumatic, a robust component designed for industrial control systems. As a 5/2-way valve, it is engineered to control the direction of air flow, typically for operating double-acting pneumatic cylinders. The valve is actuated by a single air pilot signal and features standard G1/4 threaded ports for easy integration. Its durable metal construction makes it suitable for long-term service in various industrial environments. Despite being a vintage part from 1989, it offers reliable performance for legacy system maintenance.

FAQ

What is the function of a 5/2-way valve like the TKVG-5?

A 5/2-way valve has five ports and two positions. It is typically used to control a double-acting pneumatic cylinder, allowing it to extend and retract by directing compressed air to either side of the cylinder’s piston while exhausting the other.

How is this valve actuated?

This valve is pneumatically actuated. A compressed air signal (pilot signal) applied to the ‘X’ port shifts the valve’s internal spool. It is a single-pilot valve, meaning it likely has an internal spring to return it to its original position when the pilot signal is removed.

Can this vintage Knorr valve be replaced by a modern equivalent?

Yes. While this specific model is obsolete, its function is standard. It can be replaced by any modern 5/2-way single air-piloted valve with G1/4 ports from manufacturers like Festo, SMC, or Parker, provided the physical dimensions and flow characteristics are compatible with the application.
