2 Inch Motorized Valve Full Port DN50 Low Pressure Drop
motorized valve 2 inch full-port DN50, low pressure drop for irrigation, HVAC and water-treatment applications.
Description
1. Product Overview
The motorized valve 2 inch (DN50) is a large‑bore automated valve designed for commercial and light‑industrial medium‑to‑high flow pipelines. It incorporates a full port ball, where the ball’s opening nearly matches the pipe’s inner diameter, drastically reducing flow resistance. The high‑strength forged body must be paired with a high‑torque electric actuator to drive the ball through a 90° switching cycle.
A manual override permits local emergency operation, and an optional spring return mechanism ensures automatic closure upon power loss. Both threaded (BSP/NPT) and flanged connections are available. Unlike reduced‑port designs, the full‑bore configuration prevents the valve from becoming a system bottleneck – making it suitable for water treatment, large‑scale irrigation, and energy stations in industrial parks, while resolving issues such as insufficient flow and excessive pressure drop.

3. Application Scenarios
Typical deployments include branch lines in medium‑ and small‑sized water treatment plants, main headers for large farm irrigation, central air‑conditioning energy stations in industrial parks, building main water supplies, large swimming‑pool circulation, industrial cooling systems, boiler main feedwater lines, and packaged wastewater treatment equipment.
4. Real‑World Project
At the Wasser Versorgung Graz water supply station in Graz, Austria, the motorized valve 2 inch has been installed in bulk on supply branches. The full‑bore design effectively controls system pressure drop, ensuring high‑volume water transfer while reducing pump loads. For simple on‑off control on irrigation mains, the 2‑wire motorized valve 2 inch is selected to simplify on‑site wiring.
5. Selection Guide & Distinctive Strengths
The core strength lies in the full‑bore construction: when fully open, the valve provides an ample flow cross‑section with minimal resistance, preserving the system’s designed flow rate and cutting pumping energy costs.
-
For projects where a central control system needs to read the valve’s actual open/closed status → choose the 5‑wire motorized valve 2 inch.
-
For seawater or weak acid/base media → prefer the stainless steel motorized valve 2 inch.
-
For unattended supply mains → configure with the spring return motorized valve 2 inch to automatically shut off on power failure, preventing spillage incidents.
Important note: The DN50 size demands a properly sized high‑torque actuator – never use an undersized actuator, as it will lead to damage or incomplete switching.
The product holds CE export certification; the actuator is IP54‑rated, suitable for equipment rooms and protected outdoor environments. Customisation options include flange standards, voltage, and body material. Each shipment comes with actuator selection guidelines, dimensional drawings, and pressure test reports – facilitating project design and acceptance for overseas contractors. Bulk orders are welcome, and separate replacement actuators are available to reduce future on‑site maintenance costs.
