The valve body and flange plate in current gate valves are forged and then machined and assembled together. The production of valves by forging method consumes much material, heavy weight, time - consuming, power - consuming and high cost. Dalian cast steel gate valves are especially improved for these purposes.

This product relates to a gate valve, cast steel gate valve in particular to a gate valve with a guide structure. Some technical problems are also improved: a gate valve with no bias and no friction between the gate and the seat in the process of gate lifting is provided to extend the service life of the gate valve and ensure the sealing effect of the gate valve.

Some people will ask: dalian cast steel gate valve advantages of what? The most important thing is to ensure that the cover of the gate plate will not contact with the sealing surface of the seat, which will cause friction and wear, ensure the sealing effect of the gate valve, and improve the service life of the gate valve. That's good news for manufacturers, isn't it?
