Flanged shut-off valve ZETKAMA 215 DN20 (stuffing box)

Flanged shut-off valve ZETKAMA 215 DN20 (stuffing box)

It is applied as shutoff valves on pipelines of industrial systems.

Working media: steam, water, non-flammable gases, air and other non-aggressive media compatible with the materials of the valve elements.

Design features:
The 215 Series Globe Valves are low cost shutoff valves with a metal-to-metal plug/seat seal and stem packing. The design of the valve is compact and ensures leakage-free shutoff (tightness class A). The locking element of valves up to DN50 inclusive is connected to the spindle by rolling (one-piece connection), for valves DN65 and more this connection is threaded. It is possible to replace the spindle or locking element individually.
Valves of this series have a so-called reverse seat. When the valve is fully open, the locking element is pressed against the body cover and prevents the working medium from flowing out through the spindle. This allows the spindle seal to be replaced without dismantling the valve. All you have to do is depressurize the pipeline.
