Electric Sleeve Regulating Valve

Electric sleeve regulating valve is a high-performance flow control valve that adopts a sleeve guided structure

High precision adjustment: The sleeve porous design achieves linear/equal percentage flow characteristics with an adjustment accuracy of ± 1%;

Anti vibration and wear-resistant: The guiding structure reduces valve core vibration and is suitable for high pressure differentials (PN16-PN40) and media containing particles;

Low leakage: Metal seal leakage ≤ 0.01%, soft seal can reach level VI;

Modular design: can quickly replace valve core/sleeve, suitable for different working conditions (-200 ℃~+550 ℃).

Widely used for precise flow control in harsh working conditions such as petroleum and chemical industries.

Modular interchangeability
High stability

Low noise and anti cavitation

01
Channel optimization
The cage sleeve structure disperses fluid energy, reduces turbulence and cavitation effects, and reduces noise by about 10dB compared to ordinary valves.

Long lifespan and wear resistance

01
Anti erosion design
The sleeve porous window disperses fluid impact, separates the valve core from the sealing surface, and reduces direct erosion of the medium.
02
Material weather resistance
suitable for a wide temperature range (-200 ℃~+550 ℃), metal hard seal leakage ≤ Grade IV, soft seal can reach Grade VI.

Maintain convenience

01
Online maintenance design
When disassembling the sleeve or valve core, there is no need to remove the valve body from the pipeline, greatly reducing maintenance time.
02
Simple and reliable structure
The components are assembled without threaded connections (such as self centering snap in valve seats), reducing the complexity of disassembly and assembly.

Modular interchangeability

01
Flexible adaptation to working conditions
Simply replace the sleeve to change the flow characteristics (linear/equal percentage) or flow capacity (Cv value), without the need for overall valve replacement.
02
Standardized components
The valve seat, valve core, etc. adopt a snap in structure, which is easy to disassemble and has strong universality.

High stability

01
Axial balance design
The valve plug is equipped with a balance hole to effectively counteract the force of the medium, eliminate the phenomenon of unbalanced force reversal, and avoid valve core oscillation.
02
Optimization of guiding structure
The sleeve and valve core are guided in a large area to enhance vibration resistance, suitable for high differential pressure conditions (such as PN16-PN40).
