T947H Electric Sleeve Regulating Valve
I. Introduction:
The electric sleeve special control valve adopts a cage-type multi-hole valve core, featuring good regulation performance, low vibration, low noise, reasonable clearance and less leakage. It is equipped with a guide sleeve, ensuring accurate regulation and smooth operation. The sealing surface of the valve seat is surfaced with hard alloy, and the surface of the stainless steel valve core is sprayed with hard alloy, providing excellent erosion resistance, wear resistance and long service life. The adoption of cage structure and spraying technology significantly improves the technical performance and service life of the valve. It is used for flow regulation of various fluids, including condensate systems, deaerator water level regulation, pressure regulation, condensate recirculation regulation, condensate hot water, chemical make-up water regulation and other systems, low-pressure heater drainage and emergency drainage systems, boiler drainage systems, steam-water separator to continuous blowdown, continuous blowdown to regular blowdown regulation, water tank water level regulation, steam regulation for various auxiliary steam systems, heater, deaerator heating steam regulation, and medium regulation for various oil circuit systems and steam systems.
II. Features:
1. The valve body adopts an equal-section low-flow resistance channel designed according to fluid mechanics principles, with the rated flow coefficient increased by 30%.
2. Large adjustable range, with inherent adjustable ratio of 50, and flow characteristics including linear and equal percentage.
3. The valve plug of the electric sleeve control valve is equipped with pressure equalizing holes at the upper and lower parts, resulting in small unbalanced force, good valve stability, strong sleeve interchangeability, and applicable to large operating pressure differences.
4. The regulation and shut-off type adopts a soft-seal structure valve core, meeting the Class VI leakage standard (zero leakage).
5. The servo amplifier adopts deep dynamic negative feedback, which can improve the automatic regulation accuracy.
6. The electric actuator has multiple forms, suitable for 4~20mA DC or 0~10mA DC.
7. The electronic electric control valve can directly control the valve opening through current signals, without the need for a servo amplifier.
