Top-guide Type Electric Sleeve Control Valve
Product overview
The Company produces a series of double-sealed sleeve control valve, for which sleeve-guided and pressure-balanced plugs are adopted.The control valve of this series is a double-sealed sleeve structure, which is mainly used in occasions with low leakage requirements. Bec-ause both sealing surfaces of the double seal structure are metal seals, the temperature range for use is wider.
Product Features
The pressure balanced structure is used for the plug, with small opening and closing force, and the working condition of high-pressure difference can be controlled by a small actuator thrust. It is widely used in the fluid control of medium and low temperature, medium and low pressure pipelines with good dynamic stability. It has good sealing performance and large allowable pressure difference. It has sleeve guide, with large guide area, good stability, compact structure, quick on-line replacement of valve trim, high maintenance efficiency, saving manpower and time. Balanced valve plug construction ensures minimum actuator thrust.
