Low-pressure shutoff wedge gate valves
The equipment is intended for operation as locking devices at nuclear power plants. Products are used in systems with operating pressure up to 4 MPa.
Gate valves consist of a body, a cover, a flywheel, a wedge gate and a spindle. Due to the simple structure and reliable assembly, the products are widely used in pipelines with different working media.
General characteristics
Low pressure gate valves are operated in accordance with the classification according to NP-068-05 3CIIIv, 3CIIIc.
Safety class - 3 according to NP-001-15 (at the request of the customer - according to NP-001-97), groups B and C according to NP-089-15 (at the request of the customer - according to PNAE G-7-008-89)). Products are manufactured in accordance with TU 3741-003-83789628-2018.
