The principle of our valve design is to minimalize the friction between the sealing surfaces during the working cycle of the valve and thus to prolong its lifetime. But the main advantage of this valve is the application of the fully metallic seat instead of graphite or lamellar sealing. This sofisticated solution is mostly demanded in the critical applications whenever high pressure or high temperature are present or whenever long-term tightness, operation realiability are required.
