Angle Seat Valve SSV-80
The angle seat valve SSV-80 is a bellows-sealed shut-off valve for rail tank cars transporting liquids and liquefied gas. With smooth trapezoidal spindle actuation, a doubly protected spindle and a flow-optimised interior (Kvs value 130 m³/h), it enables fast, safe loading and unloading. Type-tested in accordance with EN 14432:2014, DN 80, in cast steel (SSV80-GS) or cast stainless steel (SSV80-ES).
Safe Shut-Off
The angle seat valve SSV-80 is a bellows-sealed shut-off valve particularly suited to use on rail tank cars transporting liquids and liquefied gas. The valve body is available in both cast steel and cast stainless steel. The internal components are always made from high-alloy stainless steel.
Smooth Actuation
The special material pairing of trapezoidal spindle and trapezoidal nut prevents the slip-stick effect and thus enables smooth, judder-free movement. The valve is therefore characterised by easy actuation for fast opening and closing.
Double Spindle Protection
The spindle is protected both from the medium and from external environmental influences, ensuring trouble-free valve operation over a very long period. On the one hand, the threaded spindle of the actuating shaft is protected against environmental influences and therefore against wear caused by contamination. On the other hand, the valve is fitted with a stainless steel bellows which protects the actuating shaft from the flowing medium and at the same time ensures a leak-free seal to the environment.
The spindle feed-through is additionally sealed with a shaft seal, so that the valve spindle remains sealed even if the bellows should fail.
Maintenance-Friendly Valve Cone
The valve cone is of multi-part construction. Its design is low-maintenance and allows the cone seal to be replaced quickly and easily. The cone seal is made from PTFE as standard, but is also available in other materials on request.
Flow-Optimised for Efficient Loading and Unloading
Thanks to the flow-optimised design of the valve interior, the SSV-80 achieves a Kvs value of 130 m³/h and therefore contributes to efficient loading and unloading.
