🔵 Manual Eccentric Hemisphere Valve
Categories：
Eccentric(Offset) Hemispherical Valve
🔵 Manual Eccentric Hemisphere Valve
An eccentric hemispherical valve specially designed for water treatment and large-diameter water transmission systems.
Manual eccentric hemispherical valve adopts Eccentric hemispherical structure , by actuating the hemispherical body via the valve stem, it achieves opening and closing of the pipeline medium as well as flow control within a certain range. Compared with conventional ball valves, the eccentric design reduces friction between the sealing pairs during operation, giving the valve Flexible opening and closing, reliable operation, stable sealing performance, and long service life. and other characteristics.
🏭 38 years of valve manufacturing experience | Specializing in water treatment | A leading manufacturer of eccentric valves
⚙️ Core Product Advantages
🔹 Eccentric hemispherical structure
The hemispherical body features an eccentric design, resulting in reduced friction between the sealing surfaces during opening and closing, which helps lower operating torque and minimize wear on the sealing faces.
🔹 Reliable sealing performance
Depending on the operating conditions, appropriate sealing configurations and materials can be selected, making it suitable for pipeline systems—such as water supply, drainage, and water treatment—that demand high sealing performance.
🔹 Smooth and flexible opening and closing
It is operated manually via a handwheel or handle, featuring an intuitive design and easy operation, making it suitable for piping systems that do not require automatic control.
🔹 Suitable for large-diameter pipelines
Especially suitable for Large-diameter water transmission pipelines, water treatment plants, pumping stations, and water treatment facilities , dimensions, pressure ratings, and material configurations can be customized to suit the project’s operating conditions.
🔹 Strong adaptability to water treatment operating conditions.
It can be applied to raw water, potable water, wastewater, circulating water, and other water‑based systems, and the appropriate materials and sealing solutions can be selected based on the characteristics of the medium.
💧 Typical Applications
✓ Urban Water Supply and Drainage Engineering
✓ Water treatment plants and wastewater treatment plants
✓ Raw Water Transmission System
✓ Pumping stations and water transmission pipelines
✓ Industrial Circulating Water System
✓ Reservoirs and Water Conservancy Projects
✓ Large-diameter water supply network
✓ Seawater and special aqueous media service conditions (depending on the specific material configuration)
🛠️ Manual operation, simple and reliable
Manual eccentric hemispherical valves do not require electric or pneumatic actuators; they are operated by… Handwheel operation The valve can then be opened or closed.
For water treatment pipelines with fixed installation locations, low opening/closing frequencies, or no need for remote control, manual operation solutions offer… Simple structure, easy maintenance, and low operating costs. and other advantages.
Meanwhile, different operating configurations and accessories can be selected to suit on-site installation conditions.
