Structure Features
1. using single gate, two types of structure with diversion hole and without diversion, structure
with a diversion hole flow smoothly, suitable for oil and gas transmission;
2. Valve seat with O ring and float valve seat, it make inlet and outlet two way seal, the opening and closing torque is only half of normal valve;
3. When fully open with straight flow channel,minimum flow resistance coefficient;
4. Self seal packing structure, no need adjust and remain reliable seal; Gland box with auxiliary seal injection structure, really zero leakage;
5. When it is closed, it can automatically remove the high pressure inside the cavity;
6. Fully enclosed structure, good protection performance, can adapt to all-weather requirements.
The following data is for API 6D Flat Gate Valve, data for API 6A is available on request.
