Sliding shutters for HF

The ZMS sliding shutters for HF are designed for being used in wellhead arrangements in the process of carrying out hydraulic fracturing.

The distinguishing feature of these shutters is the use of innovation technologies for strengthening the case and the “gate-saddle” shut-off device which increases the service life of the shut-off fittings during their operation in the process of HF.
