Vessels and tanks with minimal design pressures are effectively protected against the lowest overpressure and vacuum with ELEVENT® breather valves. They reliably prevent the escape of gases, environmentally harmful substances or explosive mixtures as well as the ingress of air. A constant controlled tank pressure level is assured. The extraordinarily light and compact design is achieved with a deep-drawn stainless steel or metal housing. The clamp connections result in a modular design with interchangeable components. Maintenance can be carried out quickly and easily. The trend-setting valve concept with deep-drawn housing parts offers a flexible design of the connections, i.e. an exact adaptation of the valve to all system specifications. Connection variants with ANSI flanges, Tri-Clamp and pipe fittings according to DIN 11851 as well as CF and KF flanges are available on request.
ELEVENT® is used in the oil and gas industries, food processing, the chemical and pharmaceutical sectors and power plant technology. The optimised "air cushion" sealing principle provides a smooth valve stroke and an extremely reliable leak-tight seal. This prevents abrasion and valve chatter. The metal housing is made from deep-drawn stainless steel.
