When the position of the valve is changed, it is screwed into the landing nut, and as a result, the flow of the moving medium is shut off.Main criteria: it is easy to service and operate, high tightness. It is widely used both in pipelines and in public utilities systems. Product material brass grade LS-59-1 GOST 15527. Application temperatures + 1 ° C to + 75 ° C. Manufactured by injection molding.
