4 Inch Water Valve Full Port With ISO5211 Actuator Mount Base
DN100 full port 4 inch water valve, ISO5211 standard pad, can fit electric/pneumatic actuator for municipal & circulating water pipeline control.
Description
This DN100 (4″) water valve is primarily deployed in municipal water supply, building circulation loops, large‑scale irrigation, and wastewater treatment networks. Its main function is to isolate water flow in piping systems. The full‑port design minimises pressure losses during water conveyance, while the integrated standard mounting pad allows for easy retrofitting with various actuators – enabling either manual on‑site operation or remote automated control. It serves as a critical shutoff device in medium‑ to large‑capacity water networks.

Structural & Material Features
The valve body follows the mainstream 4 inch flanged water valve design, with grooved‑end options available for rapid on‑site installation. Internally, the full‑port passage has no obstructions or throttling protrusions, ensuring extremely low head loss even at high flow rates. An ISO5211 top flange is provided as standard, allowing direct mounting of electric actuated ball valve or pneumatic ball valve units without modifying the valve body – facilitating a simple upgrade to remote intelligent control. The EPDM seals offer good resistance to water corrosion, maintaining leak‑free performance over extended service.
Typical Applications
This valve suits municipal water stations, commercial building water recirculation, agricultural irrigation systems, and wastewater treatment plants. For example, in a commercial complex circulation system in Calgary, Canada, the entire building’s chilled‑water mains adopted the 4‑inch water valve. The full‑port design guaranteed adequate flow for the large area, while the standard mounting pad allowed batch installation of electric actuators – enabling centralised control and significantly reducing manual labour costs.
Key Advantages
Compared with reduced‑bore water valves, the full‑port design prevents media stagnation, reducing the risk of scaling and clogging. The unified actuator mounting standard means future upgrades require no valve replacement, lowering modernisation costs. The ductile iron body is coated with anti‑corrosion protection, ensuring stable long‑term performance in both outdoor and underground installations.
