High Pressure Throttle Globe Valve
Product overview
High pressure throttle globe valve is suitable for the pressure control between the outlet of water injection pump, manifold and water distribution room, as well as the pipeline control of chemical, metallurgical and power plant industries.
Product Features
1. Sealing system: from low pressure to high pressure, the sealing can be ensured in the whole range. When the valve is in high pressure difference, the sealing is reliable.
2. Pressure balance piston: under any pressure difference, it can ensure the convenience of opening and closing. The energy required for full opening (or full closing) is only 10% of that of ordinary gate valve.
3. Pressure drop: due to the small change of flow surge direction, there is no closure area, so the pressure loss is small.
4. In the sealing area, the streamline is symmetrically distributed, and compared with the general control valve, the vibration is small, the noise is low and the erosion is prevented.
