Product Description

Electric Bellows Seal Control Valve

Electric Bellows Seal Control Valve


AEAD Electric bellows seal control valve is a top entry globe type valve, which is manufactured

under ISO 9001 quality assurance system. The body channel is streamlined by S shape with low 

pressure loss, high capacity, wide regulating range, and high accuracy in flow characteristics.

Bellows seal bonnet can reduce the possibility that the processing medium let out from the backlash 

of stem moving. This is oneremarkable characteristic of bellows seal valve. As the deformation

and anti-ageing of the bellows seal control valve, these kinds of valve have totally overcame the 

disadvantage of packing ageing and sensitivity of temperature difference of packing seal valve. It

has a wide application in the auto control systems with the special rare medium, such as poison, 

strong corrosion, and radioactivity. The plug features with guiding area and good vibration resistance.

The control valve is equipped with electric actuator and compact in structure as well as big in output

force. This valve is designed to control a broad variety of fluids, like steam, water, most of the medium

and gases.



1. Reduced trim can be chosen to provide wide capabilities for site applications 
2. Bellows seal bonnet to prevent the leakage from the backlash of stem moving
3. Electric actuator for wide application
4. Balanced trims are suitable for high pressure drop and shutoff 
5. Hardened trims to handle high pressure drop applications
6. Bellows seal for special medium
7. Extended bonnet for low temperature 
8. Finned bonnet for high temperature 
9. Higher maximum valve flow coefficients 
10. Bigger body volume to reduce cavitations
