ZDSH65 (50,100) – 210 (140,160,350) M

TU 3741-001-49652808-2000

The gate valve is designed for installation on high-pressure pipelines or for operation as part of Christmas tree or injection valves.

The unique design feature of the gate valve made it possible to obtain a number of advantages over the gate valves of the “classic” design:

  • ¥ “Opening-closing” of the valve is carried out by the handle;
  • ¥ free internal volumes are minimal (since the gate rotates around its axis), which makes it possible to exclude freezing of the working medium in cavities at low temperatures

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

The ZDSH gate valve is made on the basis of the ZD 65-210M gate valve with similar technical characteristics and includes quick-change mineral ceramic fittings with throttling holes 2; 3; 4; 5; 6; 7; 8; 10; 12 mm (by order of any completeness and diameter).

Designed for stepwise regulation of fluid flow (industrial water, oil, etc.) and is installed on high-pressure pipelines instead of choke blocks.

The use of fittings made of mineral ceramics has shown their high wear resistance and durability.

Replacing the fittings in the gate valve is performed by one operator within 3-5 minutes with the gate closed position without relieving pressure from the system.

On request, the gate valve can be equipped with a non-return valve preventing the overflow of the working fluid in the opposite direction.
