Katup Semi-Bola Eksentrik Terpasang Trunion DELCO
Eccentric Half-ball Valve (Eccentric Half-ball Valve) is a kind of industrial valve, which is successfully developed by absorbing and integrating the advanced technology at home and abroad. Its design feature is that the ball is not located in the centre of the valve, but is installed eccentrically. The metal ball crown is fixed on the eccentric sphere, and the valve is opened and closed by rotating the eccentric crankshaft by 90 degrees. This design effectively reduces the friction and wear of the ball during operation, and is particularly suitable for the transport of easily scaled media. The hemispherical part of the valve fixes the metal crown on the eccentric sphere, and assembles different alloy crowns on the sphere, and the valve seat also overlays the alloy accordingly, and after special treatment, the sealing surface is equipped with anti-corrosion, abrasion-resistant and high-temperature-resistant and other characteristics, which can satisfy the needs of different working conditions. The valve seat and ball crown are designed with a certain amount of compensation, so that when the valve seat is worn out, a slight rotation when closing can still maintain a reliable seal, thus extending the service life of the valve and improving the operational efficiency. Eccentric half ball valves are widely used in industrial fields that require frequent operation and strict flow control, such as paper mills, waste water treatment and petrochemical and other fluid control systems.
Model: Eccentric Half Ball Valve
Size Range: 2″~24″(DN50~DN600)
Pressure Range: ASME CLASS 150~600(PN16~PN100)
Material: Carbon steel, stainless steel, alloy steel
Fitur
- Flexible operation: manual operation device enables the valve to respond and adjust quickly to meet the actual needs.
- Strong adaptability: the alloy material enables it to cope with the fluid control needs of various media and working conditions.
- Wear-resistant and anti-corrosion: Surfacing alloy and special treatment, the sealing surface with anti-corrosion, wear-resistant and high temperature resistance characteristics, suitable for different applications.
- Easy maintenance: simple structure, after the system is depressurised, it can be inspected and repaired online by opening the bonnet to lift out the ball crown and support body without dismantling the whole valve.
- Reduce friction and wear: Eccentric design reduces the contact area between the ball and the valve seat, reducing friction during opening and closing, and the seat and crown are designed with a compensating amount, so that a slight rotation can maintain a reliable seal after wear, prolonging the life of the valve.

Aplikasi
1. Wastewater treatment:
Eccentric hemispherical ball valves demonstrate superior anti-clogging performance and wear-resistant characteristics in handling media with solid particles and sludge during wastewater treatment. They effectively regulate wastewater flow, reduce maintenance requirements, and prolong equipment lifespan.
2. Paper industry:
In the paper industry, eccentric hemispherical valves control the flow of pulp and chemicals. Their eccentric design and robust sealing structure prevent scaling and wear, ensuring an efficient and stable production process that can handle high-viscosity and high-solids media.
3. Chemical processing:
The chemical industry necessitates handling corrosive media, high temperatures, and high-pressure environments. Eccentric half-ball valves’ corrosion resistance, wear resistance, and capability to withstand high temperatures make them ideal for controlling acids, alkalis, solvents, and other chemical fluids, ensuring system safety and reliability.
4. Oil and gas pipelines:
Valves in the oil and gas industry must operate reliably under high pressure, high temperature, and corrosive conditions. Eccentric semi-ball valves effectively control oil and gas flow, ensuring the safety, efficiency, and reduced maintenance of pipeline systems.
5. Power generation industry:
Eccentric half-ball valves in power plants regulate the flow of cooling water, steam, and fuel. Their high abrasion resistance and superior sealing performance enable stable operation in high-temperature, high-pressure environments, thereby reducing valve failures and enhancing the efficiency and safety of power generation equipment.
6. Hydraulic deslagging:
In hydraulic deslagging systems, eccentric hemispherical ball valves manage fluids containing solid particles and corrosive substances. Their design effectively prevents wear and clogging, ensuring continuous and efficient operation of the deslagging process.
