Universal centring system
revoseal System Vario
Centring rings of gaskets with the same nominal size but different pressure ratings differ only in their outside diameter. Installing non-matching dimensions can lead to incidents and gasket failure. The centring segments of the Vario system compensate for different outside diameters: misuse is prevented, the number of stock variants falls and plant availability increases.
1 for 8
One Vario gasket can replace up to eight gaskets for DIN and ASME flanges of the same nominal size
Highlights
What sets Vario apart
Fewer variants
One gasket covers several pressure ratings and flange standards. The number of gasket types kept in stock drops considerably.
Exact centring
The shape of the centring segments compensates for different outside diameters. There is no risk of the gasket sitting off-centre.
No mix-ups
Non-matching dimensions can no longer be confused, preventing incidents and gasket failures.
Easier installation
Time-consuming positioning with reduced-shank bolts is no longer necessary. Procurement and storage become significantly cheaper.
How it works
One system for DIN and ASME
Vario centring system
The revoseal Vario centring system is available for the encapsulated profile gaskets JG and JP developed by revoseal.
Example DN 150 / 6"
A customer with DIN flanges up to PN 160 replaces four gaskets (PN 10/16, PN 25/40, PN 64, PN 100/160) with one Vario gasket. The same applies to ASME flanges up to Class 600 (Class 150, 300, 400, 600). Where both standards are in use, one Vario gasket replaces eight gaskets from two standards.
