Variseal® are effective in a wide range of applications. They are chosen when higher resistance to chemical media is required, if the seal is required to operate in extremes of temperature and/or where good extrusion and compression characteristics are needed.
Method Of Operation
All Variseal® designs included on this page have the same operating principle and differ only in their profile form and the type of metallic spring used.
The Variseal® spring supplies the load required for sealing at low pressures (Figure 1). The “U” shaped jacket allows fluid pressure to energize the sealing lips, so total sealing pressure rises with increasing operating pressure (Figure 2).
