pressure lid

The "Spirig" pressure covers are a cost-effective solution when you need a manhole to the water chamber. They can be used as access to containers, especially in water supply systems and stormwater overburden tanks.

Pressure-resistant up to a water column of 10 m, opening on the pressure side, and flexible in terms of wall thickness. We offer various solutions to give the seal the necessary preload.

From the simple clamping bracket to the sophisticated self-twisting four-point locking system.

We have the right solution for every requirement.
