## Overview

The U.S. Solid 1" Brass Motorized Ball Valve DN25 is a high-performance, energy-efficient valve designed for professional and DIY irrigation or fluid control systems. Featuring durable brass construction with British Standard threading, it operates on 9-24V AC/DC with a rapid 3-5 second open/close cycle. Its innovative 2-wire automatic return setup ensures the valve safely closes on power loss, preventing overwatering or leaks. With a lifespan of up to 100,000 cycles and near-zero power consumption when idle, it’s a reliable, cost-effective alternative to traditional solenoid valves.

## Description

The U.S. Motorized Ball Valve Solid 1" Brass with Auto Return is a blessing for many DIYers. The body and stem of this valve are made of brass. The valve will activate when AC or DC power from 9V to 24V is brought to it. The valve is normally closed, when powered on, it opens in 3-5 seconds. Then the limit switches will keep the power production at a negligible level. If the power is turned off, the valve will return to a closed position. Most solenoid valves are fully powered on when opened, which can lead to overheating. This valve takes so little energy once fully opened, so it will never be overheated. Specifications Valve Material: Brass Ball Seat: PTFE Seals: silicone rubber Close/Open time: 3-5 seconds. Working voltage: 9-24 V AC/DC. Maximum power: 5 W Max torque: 2 N m Max Pressure: 1.0 MPa Temperature range for medium: 0°C - 90°C Ambient temperature: -10°C - 40°C Housing classification: IP65 Life expectancy: 80,000-100,000 cycles Thread Type: G Standard Port, 20 mm WARNING: This product may expose you to chemicals, including lead, which is known to the State of California to cause cancer and birth defects or other reproductive disorders. And it is not allowed to be installed in drinking water pipes.

Review: Great product - Tested and works perfectly. Using it for an automated gravity fed irrigation system, automatic close on power removal/failure is a great feature for preventing over watering. Uses virtually zero current when in the open position too.
Review: Electric Ball Valve - Motorhome use - I got so fed up of having to get out the cab (motorhome) walk round to a locker door, open that then pull a lever - like an old fashioned handbrake - then kneel down on the floor to undo a large black waste water cap to release the grey water tank contents, i looked into an electronic waste water gate that would connect in line with the waster water hose but found they were very expensive, so i purchased this for less than £50 then purchased a few stepper flexi pipes from my local caravan/camping shop - less than £10, fitted this ball valve in line and made a bracket to support it under the van, ran the electrics straight to the battery with an in line fuse and then onto a toggle switch mounted by the driver on the dashboard, i now dont even after to get out my seat to empty the waste tank, for me personally this has been one of many best things ive fitted - along with solar panels etc. . well worth the money and effort to fit it - highly recommended for this use.

## Features

- G THREADING- 1” Brass threading, manufactured and measured according to British Standard Pipe Thread.
- 9V-24V AC/DC- Works effectively over entire voltage range; Will open or close valve in 3-5 seconds; No power expended once fully open or fully closed.
- 2 WIRE AUTOMATIC RETURN SETUP- Simple two wire connection, valve largely de-energizes after opening; Returns to fully closed if power is removed.
- ALTERNATIVE TO SOLENOID VALVES- Automatically cuts off power once fully open or fully closed; This reduces likelihood of overheating, making it a great alternative to solenoid valves for projects where a valve needs to be open for an extended period of time.
- RELIABLE- Lifespan of 80,000-100,000 cycles means a valve that will last.
