Full Bore Horizontal Hemispherical Valves
🔵 Horizontal Full-Bore Hemisphere Valve
Full-bore design · Low flow resistance · Abrasion‑resistant · Suitable for large‑diameter water treatment and water transmission systems
A horizontal full-bore hemispherical valve is a type of valve suitable for… Large-diameter pipelines and water treatment systems of the spherical valve. The valve body adopts a horizontal configuration, and the internal flow passage utilizes Full-bore design After the valve is opened, the flow passage of the ball is essentially aligned with the pipe’s inner diameter, effectively reducing local resistance and energy loss as the fluid passes through the valve.
🏭 38 years of valve manufacturing experience | Specializing in water treatment | A leading manufacturer of eccentric valves
⚙️ Why choose a full-bore ball valve?
🔹 Full‑bore flow path | Reduces hydraulic losses
Once the valve is opened, it establishes a continuous, smooth flow path, resulting in low flow resistance and making it well suited for piping systems where minimizing pressure loss and maximizing conveyance efficiency are critical.
🔹 Suitable for large-diameter water transmission pipelines
Especially suitable for Large-diameter water supply, raw water conveyance, wastewater treatment, pumping stations, and hydraulic engineering projects , can be configured with different diameters and pressure ratings to meet specific project requirements.
🔹 Excellent erosion resistance
The hemispherical design helps mitigate the direct impact of the process fluid on critical internal components, and the ball, seat, and wear‑resistant materials can be selected to suit the specific characteristics of the fluid.
🔹 Stable opening and closing operation
The valve is opened and closed by rotating the hemispherical disc via the valve stem, featuring a compact design and stable operation. It can be equipped with manual, electric, or other actuation methods to meet project requirements.
🔹 Easy to inspect and maintain
The structural design fully accounts for long-term operation and on-site maintenance requirements, making it well suited for installation in water‑transmission and water‑treatment systems that demand stable, reliable performance over extended periods.
💧 Applicable Media
Horizontal full-bore hemispherical valves are primarily suitable for:
✓ Raw water
✓ Clear water
✓ Wastewater
✓ Recirculating water
✓ Industrial water use
✓ Reservoir water conveyance
✓ River water
✓ Other liquid media
Targeting Media containing silt, particulates, or exhibiting a certain degree of abrasiveness , the appropriate wear-resistant structure and materials can be selected based on the specific operating conditions.
🏗️ Typical Application Areas
Urban water supply system
Used for urban water supply main lines and large-diameter water transmission pipelines.
Water treatment plant
Suitable for raw water, treated water, and process water conveyance systems.
Wastewater Treatment Project
It can be used for sewage conveyance and related process pipelines.
Pumping station system
Suitable for pump station inlet and outlet pipelines as well as large-diameter water transmission systems.
Water conservancy project
It can be used in reservoirs, river channels, water diversion projects, and large-scale water conveyance systems.
Industrial circulating water
Suitable for circulating water and process water pipelines in industrial enterprises.
🛠️ Advantages of a full-bore design
Compared with conventional valves featuring reduced‑diameter flow passages, Full-bore hemispherical valve It can reduce the local resistance caused by changes in pipe cross-section.
In large-diameter, long-distance water transmission systems, the flow resistance of the valves themselves directly affects the operational efficiency of the entire pipeline network. Therefore, for… Large DN, high flow rate, and long continuous operating time The engineering project, with its full-bore design, exhibits significant practical value.
Meanwhile, the full-bore flow path facilitates the passage of the internal medium and also supports pigging and maintenance of certain pipeline systems.
🔧 Optional operation mode
Depending on the on-site automation requirements, different operating schemes can be configured:
⚙️ Manual operation — Suitable for piping systems with low opening and closing frequency.
⚡ Electric operation — Suitable for remote control and automation systems
💨 Pneumatic operation — Suitable for applications requiring rapid opening and closing.
🔄 Other drive methods —— Can be configured according to project control requirements.
