A cylinder that has to vent its air back through a long hose and a small valve will always return slowly. The ASCO 34600137 is a Series 346 quick exhaust valve with G3/8 ports that dumps that air at the cylinder.

A quick exhaust valve is fitted close to a cylinder port. When the control valve vents, the quick exhaust valve dumps air directly to atmosphere instead of sending it back through the hose and control valve, which can greatly speed up cylinder return.

Accessories are easy to overlook, but they shape how efficient and reliable a pneumatic circuit is. The wrong fitting or a cheap substitute can leak, restrict flow or fail under vibration, and that air loss costs money every hour the compressor runs. A genuine ASCO accessory matched to your valves keeps the installation tidy, leak-tight and easy to service, and it avoids the fit problems that come with mixing brands.

The ASCO 34600137 is part of ASCO's Series 346 range of pneumatic line accessories.
