Safety valves made of stainless steel, angle-type with threaded connections.


The consequential expansion of the valve series 451 with smaller nominal diameters now allows the best and therefore most efficient design of safety valves with smaller discharge volumes.
The proven versatility in different variations leads to use for a variety of media with different aggregate conditions. The possibilities for use are in medical process equipment construction and in the food, beverage, pharmaceutical and cosmetics industries in secondary areas.
