Product Description
The Festo VBQF is a flat, screw-in quick exhaust valve designed for reduced noise emission, enabling higher piston speeds on the return stroke of single and double-acting pneumatic drives . With a minimal height and available ducted (VBQF-D) or unducted (VBQF-U) exhaust air configurations, this valve significantly improves cycle times while maintaining a balanced acoustic profile .
Key Features & Advantages:
Minimal Height & Rotatable Design: The ultra-flat, compact design allows for mounting in tight spaces. The valve can be rotated 360° after installation, providing flexible alignment of connections without compromising performance .
High Flow Rate for Maximum Cylinder Speed: Delivers exceptional flow rates (up to 2,500 l/min depending on variant) to dramatically reduce back pressure and increase piston return speeds . For G1/8 variants, exhaust flow reaches 1,300 l/min .
Reduced Noise Emission: Unlike traditional quick exhaust valves, the VBQF features calibrated noise emission control. The "D" versions come with a silencer for ducted exhaust, significantly reducing workplace noise pollution .
Robust Metal Construction: Housed in die-cast zinc and die-cast aluminium, these valves are strong and durable, suitable for harsh industrial environments (CRC 1) .
Versatile Connection Options: Available with threaded connections (G1/8, G1/4) or push-in fittings (QS-6), allowing direct integration into new or existing systems .
