GEA offers different types of safety valves: Hygienic vacuum valves are used to secure lines in processing plants against impermissibly occurring vacuums (e.g. after sterilization). Our safety relief valves reliably protect process plants from overpressure.
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.
