BOVE Through-Conduit Slab Gate Valve is a position-sealed valve that uses spring pre-tensioning to provide the initial sealing force to the gate and seat under low pressure. The higher the medium pressure, the more reliable the sealing performance. The flat gate valve has a diversion hole and can be cleaned by sweeping the pipeline. It complies with the latest API6D and NACE MR-0175 specifications and is widely used in oil and gas pipelines.
Technical Features:
1. The full bore design can effectively eliminate eddy currents and pressure drops and achieve pipeline pigging.
2. Bidirectional seal.
3. When the pressure is high, the medium pressure starts to assist the seal, and when the pressure is 4. low, the spring and the O-ring assist the seal.
5. The seat sealing surface is not in the flow channel, reducing erosion.
6. The single-piston effect DBB valve seat has the function of self-releasing cavity pressure.
7. Valve seat and valve stem have secondary grease injection sealing device
