KREISEL DOME VALVES®

The KREISEL DOME VALVE® is a pilot-controlled safety valve. It is used at counter pressures being higher than those for standard valves. Thus they have a positive influence on the planned operating pressure and the system design. The KREISEL DOME VALVE® as a gas-tight isolation valve in pressure vessels was developed in Krauschwitz. The benefits arise from the cross-section being available to 100% in the opening condition. When opening or closing the dome valve, any relative motion between calotte, dome and pneumatically controlled sealing is exlcuded. The sealing is inflated by means of control air and pressed to the dome. Particles of bulk material smaller than 2mm are effectively retained. The KREISEL Dome valve tightly seals against high differential pressures.
