A flat gate valve is a sliding valve in which the closing members are parallel rams. The closing member may be a single shutter or a double shutter with a distracting mechanism therebetween. The pressing force of the shutter to the valve seat is controlled by the medium pressure acting on the floating shutter or the floating valve seat. In the case of a double gate flat gate valve, the expansion mechanism between the two shutters can supplement this pressing force.


Flat gate valve structure

Second, structural characteristics and working principle

1. It adopts floating valve seat, two-way opening and closing, reliable sealing and flexible opening and closing.

2. The valve body has high bearing capacity, and the channel is straight-through. When fully open, it is similar to the straight pipe of the ram and the flow tube is small. The valve stem adopts composite packing and multiple sealing, which makes the sealing reliable and the friction is small.

3. Due to the double seal, the consumables can be replaced without affecting the work of the pipeline. This is an important feature of our products in preference to similar products at home and abroad.


Advantages of Resin Sand Casting

The new casting coating is improved and adjusted on the basis of the traditional casting coating. It can effectively prevent the oxidation of liquid metals at high temperature, and can not react with the casting mould and liquid metals at high temperature. And can absorb and digest nitrogen, sulfur, carbon and other gases.

Thus, the following problems can be solved thoroughly: sand sticking, sand hole, rough casting, blowhole, inclusion [slag], variation of ball mill iron, sulphurizing crack of cast steel, carburizing defect, etc.


What service we offer?

We offer you OEM service for casting parts , especially in sand casting.

Sand casting,also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand casting is relatively cheap and sufficiently refractory even for steel foundry use. In addition to the sand, a suitable bonding agent is mixed or occurs with the sand.
