ZD 65(50,80,100)-140(210,350)M
TU 3741-001-49652808-2000
Disk gate valve is intended for installation on the high pressure pipelines,
“classical” design:
- “opening-closing” is performed with the handle;
- free inner space is minimal (gate revolves around its axe) and allows to perform opening-closing of the disk gate valve without preheating in low temperatures.
ZD connection sizes are similar to ZMS gate valves (there’s a possibility to make gate valves according to the Customer’s requirements).
