Main Features:

Expanding gate valve is an efficient and reliable through-conduit gate valve, with two floating seats and parallel expanding gate and segment. The expansion action between gate and segment provides a tight mechanical seal on both upstream and downstream. Full bore through conduit design can eliminate flow turbulence. Pressure drop is no larger than through an equal length of pipe

Product Features：

1.Bidirectional seats design, so the seats can be sealed against pressure source in either direction.

2.Bidirectional seals, no limitation on the flow direction；

3.When valve is in full open position, seat surfaces are outside flow stream that always in full contact with gate that can protect seat surfaces, and suitable for pigging pipeline;

4.Non-rising stem design can be chosen;

5.Spring loaded packing can be chosen;

6.Low emission packing can be chosen according to ISO 15848 requirements;

7.Extended Stem design can be chosen;

8.Normally open type or normally close type with Through conduit design;
