Electric sleeve regulating valve T947H
Other Products
I. Introduction:
The electric sleeve-type 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 stable operation. The sealing surface of the valve seat is hardfaced 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 application of the cage structure and spraying technology significantly improves the technical performance and service life of the valve. It is used in various systems such as flow regulation of different fluids, condensate water systems, deaerator water level regulation, pressure regulation, condensate water recirculation regulation, condensate hot water and chemical make-up water regulation, low-pressure heater drainage and emergency drainage systems, boiler drainage systems, steam drum to continuous blowdown, continuous blowdown to intermittent blowdown regulation, drain tank water level regulation, steam regulation of various auxiliary steam systems, and heating steam regulation for heaters and deaerators, as well as medium regulation of various oil circuit and steam systems.
II. Features:
1. The valve body adopts an equal cross-section low flow resistance channel designed according to fluid mechanics principles, with the rated flow coefficient increased by 30%.
2. It has a large adjustable range, with an inherent adjustable ratio of 50, and the flow characteristics include 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, achieving leakage class VI (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, applicable to 4~20mA DC or 0~10mA DC.
7. The electronic electric control valve can directly control the valve opening degree via current signals, without the need for a servo amplifier.
