Full Stroke (Rail Car) VALVES

Rieger‘s aseptic and hygienic Full Stroke Valves are best-in-class valves for high
viscosity products, such as tomato paste, jam or smoothies. With the full cylindric
stem, the valves open to 100% of the tube size, which avoids any dead spaces within
the valve and reduces pressure drops to a minimum. An optional steam barrier
guarantees hermetic sealing against the environment.
Industries of application: tomato processing, food, dairy and cosmetics.
