- The bearing seat is equipped with a special oil cup for lubricating the bearing.
- The bonnet sealing ring adopts pressure self-tightening metal sealing ring.
- All-metal seals are used between the gate and seat, and the seat and valve body.
If required, the stem and tailpiece can be inverted sealed, allowing the stem packing to be replaced under pressure (for safety, it is recommended that the packing be replaced after the pressure is relieved).
- GBS-R gate valves are equipped with a lubricator at the lower part of the upper stem and at the shoulder of the tailstock inverted sealing table for emergency grease sealing of the stem and greasing of the valve body center cavity.
- The tailstock is used to maintain pressure balance with the upper stem to reduce operating torque. Prevent the pressure in the middle chamber from increasing during operation, and the tailgate can provide position indication GBS series gate valve has two non-rubber Lipsea|seals between the gate and seat, the sealing ring is a spring-accumulated, pressure self-tightening sealing, which can realize Lipsea|sealing at low pressure and metal sealing at high pressure, and this sealing structure effectively prevents wear of metal sealing surfaces between the seat and the gate and improves the sealing performance of the valve at lower pressures. 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 intrusion of particulate matter into the valve body cavity, thus preventing sand influence.
- Metal sealing surfaces between the valve body and seat, seat and gate, and protects the valve body from corrosion under drilling fluid conditions.
- Dual flow design provides flow versatility and extends valve life
- The stem packing is a pressure self-sealing 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.
