Shut-off valves of carbon, alloyed and stainless steel, types STK-VZS.

Shut-off valves are designed for installation as shut-off valves on technological pipelines. Shut-off valves are used for complete closure of its passage section, and therefore the flow of the working medium, that is, the locking element, which in the shut-off valve is most often a spool, in the process of operation is in the extreme positions of "open" or "closed".
Control of shut-off valves can be manual (by handwheel or through a gearbox) or from a general purpose or explosion-proof electric actuator.
Connection types: coupling (internal thread), under welding "in socket", flanged, flanged with mating flanges, under butt welding, socket (external thread).
Field of application: Chemical, oil, gas, power and food industries.
Working media: Water, steam, gas, oil products and other non-aggressive media neutral to basic materials of valve parts.
