- The bearing seat is equipped with a special oil cup for lubricating the bearing.
- The stem is provided with an inverted seal structure, which allows the valve to replace the stem packing under pressure (for safety, it is recommended that the packing be replaced after the pressure has been relieved).
- The lower part of the bonnet is equipped with a lubricator, which can be used for emergency sealing of the valve stem and lubrication of the stem nut and gate plate.
- Metal seals are used at the bonnet (for pressures of 10,000 psi and above, BX self-tightening metal seals are used, and for pressures of 5,000 psi and below, flat gasket metal seals are used).
- There are two non-rubber Lipseal seals between the gate and seat of GBS series gate valve, the sealing ring is spring accumulator, pressure self-tightening sealing, which can realize Lipseal sealing at low pressure and metal sealing at high pressure, this sealing structure can effectively prevent the wear of the metal sealing surface between the valve seat and the gate and improve the sealing performance of the valve at lower pressure. This double seal design minimizes the possibility of particulate matter intrusion into the cavity of the valve body, thus preventing sand particles from affecting the metal sealing surfaces between the valve body and seat, seat and gate, and protects the valve body from corrosion under drilling fluid conditions.
corrosion of the valve body under drilling fluid conditions.
- All-metal sealing between the gate and the seat, and the seat and the valve body.
- Simple, reliable gate and seat design facilitates oilfield service.
- The dual flow design not only provides flow versatility but also extends valve life.
- The stem packing is a pressure self-sealing ring that serves a wide range of temperatures and fluids and is coated with a nonrubber material that provides a low coefficient of friction for reduced torque.
- Various types of actuators are available.
