The Warex Valve System APS impresses with its constant, reliable pressure tightness and ensures a safe, gentle shut-off with minimal friction. This is an obvious advantage, especially with sensitive media and aggressive bulk materials. It goes without saying that we can also provide special designs.


1. Valve open

The special APS shut-off valve (Air-Pressure-Sealing) has a valve disc which is smaller than the corresponding sealing sleeve. The disc can close easily.

2. Valve closed

There is still a small gap remaining between the valve disc and sleeve – in this state, the fitting can be opened again with minimal torque.

3. Valve pressed

When the valve is closed, air is blown evenly on the seal, which ensures a secure and gentle shut-off with minimal friction. This is a major benefit with aggressive bulk materials, in particular.
