SAFETY VALVE FOR EXTREME CHEMICAL EXPOSURE

Feature produced  safety valves have exceptional resistance to all acids, solvents, oils, alkalis; inertia and resistance to water vapor, weather resistance, climatic and bacterial influences; with the exception melt alkali metals, solutions of alkali metals in ammonia, chlorine trifluoride and elemental fluorine at high temperatures.

Operating temperature range - up 196 °C to 260 °C.

Today we offer safety valves to prevent overpressure, vacuum or double action, with flanged or threaded connection with a working pressure up to 5 atm.

The safety valve can be used for installation on tanks from polymeric, composite materials, and metal.

Can be applied to a very aggressive environment (acids, alkalis and other aggressive products), also applicable for installation on a tank with foodstuffs.
