ZDSh 65(100)-140(160,210,350)Mr
TU 3741-001-49652808-2000
Disk gate valve ZDSh Mr is designed on the basis of the disk gate valve ZD with equivalent technical characteristics. It is intended for step control of the flow (technical water, oil and etc.) and natural gas. It is installed on the high pressure pipelines instead of the choke blocks. Control of the gate position is performed according to the indication on the limb.
ZDSh connection sizes are equivalent to ZMS (there’s a possibility to make gate valves according to the Customer’s requirements).
