Disk revolving gate valve

ZDSH65 (100) – 210 (140,160,350) Мр

TU 3741-001-49652808-2000

The ZDSH MR gate valve is made on the basis of the ZD gate valve with similar technical characteristics.

Designed for stepwise regulation of the flow rate of liquid (industrial water, oil, etc.) and gas. Installed on high-pressure pipelines instead of choke blocks. The revolving gate has non-removable multilayer-coated fittings. The change in the flow area occurs by turning the gate to the required angle along the dial of the indicator.

The connecting dimensions of the gate valve are similar to ZMS (or any others on request).
