C-G4 Through conduit gate valve,Fully welded Slab gate valve


C-G4 Through conduit gate valve is a type of flat gate valve developed according to

the demand of petroleum pipeline. The body and bonnet are made of ASTM A516 GR70 steel plate. Compared with flat gate valve casting molding, to avoid the quality defects such as sand holes, loose, deformation, the model of flat gate valve designed by American standard API6D pipeline valve, mainly used in oil pipeline, city pipeline network, with diversion Kong Quan sizes, DBB double block structure, double emissions can connect the inlet and outlet of the cleaning ball cleaning pipe and sealing pressure double insurance sealing function. In addition, we also specially improve the structure of the packing part of the flat gate valve, and the packing has a true triple seal effect.



Design standard :API 6D

Product range :
1. Pressure range :CLASS    150Lb~600Lb
2. Nominal diameter :   NPS        2~48″
3. Body material:ASTM A516 GR70/A515 GR60
4. End connection : RF   RTJ   BW
5.Mode of operation:Hand wheel, Gear box, Electric, Pneumatic, hydraulic device,

   Pneumatic-hydraulic device;

Product features:
1. Double block and bleed seat design;
2. Operating torque is smaller than normal gate valve;
3. Bidirectional seals, no limitation on the flow direction;
4. 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;
5. Spring loaded packing can be chosen;
6. Low emission packing can be chosen according to ISO 15848 requirements;
7. Stem extended design can be chosen;
8. Normally open type or normally close type with through conduit design;
