Brass Two-Way Three-Way Ball Valve DN15-DN50 Threaded 1.6MPa 95C Electric Actuator Manual Automatic Integrated for Solar Water Tap Air Conditioner
Brass Electric Ball Valve DN15-DN50 with Manual Automatic Actuator

This brass ball valve is designed for controlling water flow in solar water heating and air conditioning systems. It combines a manual override with an electric actuator, so you can operate it by hand during setup or use the motorised function for everyday switching. The valve is available in two-way and three-way configurations across nominal diameters from DN15 to DN50, giving you a size to match common domestic and light commercial pipework. The brass body and PTFE seals are rated for a working temperature of 95°C and a nominal pressure of 1.6MPa. Threaded connections keep installation straightforward with standard fittings.
Features and Construction

The valve is built around a brass body with PTFE sealing material, which is suited to the stated temperature and pressure range. The manual and automatic integrated actuator includes a built-in limit switch to control valve movement. This section covers the main materials and the sizes available.
Material and Build
The body is made from brass, a common choice for water pipework because it resists corrosion and holds up well in closed systems. PTFE is used for the sealing material, which helps maintain a tight seal at the stated working temperature of 95°C. The electric actuator has a built-in limit switch that stops the motor at the end positions. The nominal pressure rating is 1.6MPa. No other coatings or finishes are stated in the source information.
Size and Practical Fit
Nominal diameters run from DN15 to DN50. In the available options, DN15 is described as 4 points, DN20 as 6 points, DN25 as one inch, DN32 as 1.2 inch, DN40 as 1.5 inch, and DN50 as 2-inch. Both two-way and three-way versions are offered. The connection method is thread, so the valve fits standard threaded pipe fittings. Choose the size that matches your existing pipework.
Uses and Placement

These valves are suited to water-based heating and cooling pipework where flow needs to be switched or diverted. The manual and automatic functions make them useful in systems that need occasional manual adjustment as well as regular powered operation. This section outlines event and professional use alongside everyday home applications.
Event or Professional Use
In solar water heating installations, a two-way valve can isolate or open a flow path, while a three-way version can divert water between circuits. Air conditioning pipework can also use these valves for flow control. The 220V actuator with built-in limit switch supports consistent positioning. The threaded connection and brass body suit standard pipe fitting work. Sizes up to DN50 cover larger pipe runs.
Everyday Home Use
For home solar water systems, the manual override lets you operate the valve during maintenance or if power is interrupted. The automatic mode handles regular switching without needing to reach the valve by hand. A three-way valve can direct flow between two outlets, which is useful in simple diverting setups. The DN15 to DN25 sizes are most likely to match common household pipework, while larger sizes suit bigger systems.
Benefits and Buying Value

The main practical benefit is the combination of manual and automatic control in one unit, which reduces the need to choose between the two. Brass and PTFE construction support the stated pressure and temperature ratings. This section covers reuse, maintenance, and the reasons to choose this valve.
Reuse and Low Maintenance
The brass body and PTFE seals are materials that suit long-term use in water systems when operated within the stated limits. The built-in limit switch helps prevent over-travel, which can reduce wear on the actuator. Routine checks for leaks at the threaded joints and a test of manual operation are sensible low-risk practices. No specific service interval is given in the source data.
Why Choose This Product
This valve offers a single unit that can be operated by hand or by the 220V electric actuator. It comes in two-way and three-way configurations and in nominal diameters from DN15 to DN50, so you can match it to a range of pipe sizes. The brass body and PTFE sealing material are stated for a working temperature of 95°C and a nominal pressure of 1.6MPa. Threaded connections keep installation simple.
