A GEA oferece diferentes tipos de válvulas de segurança: As válvulas a vácuo sanitárias são usadas para proteger as linhas em plantas de processamento contra a indesejada ocorrência de vácuo (por exemplo, após a esterilização). Nossas válvulas de segurança protegem de modo confiável as plantas contra a sobrepressão.
Constant Pressure Valve VARIVENT®, Type DHV
VARIVENT® constant pressure valves are used to adjust the inlet pressure of the valve on a constant level. In case of any process-related pressure fluctuations, the valve opens or closes to compensate them. The needed product pressure will set through the air supply pressure to the actuator. Therefore a constant air control pressure is required.
Safety Valves VARIVENT® 488, 483 & Hycom
VARIVENT® Safety valves were specially developed for the food, beverage, and pharmaceutical industries and meet all the relevant standards and regulations such as DIN 11866 or ASME BPE.
Vacuum Valve VARIVENT®, Type V
VARIVENT® vacuum valves are designed to hygienically protect tanks against vacuums. A protection is already ensured when a vacuum surpasses -2.5 mbarÜ. To minimize the cleaning effort and to protect the valve disc against conglutination, the seat ring is non-stick coated.
