What Is the PURO XD12 Water Inlet Valve?

The PURO XD12 is a DC 12V solenoid-operated water inlet valve with a 6.5mm 2-point connection, rated at 6.5W. When energized, the solenoid opens to allow water flow; when de-energized, a spring returns the valve to the closed position. Commonly found in appliance and fluid handling systems, from coffee machines to laboratory water circuits.

In short: A normally-closed DC 12V solenoid water valve with 6.5mm barbed inlet — opens electrically to allow water flow in appliances, dispensers, and automated fluid control systems.

Key Features

1. Normally-Closed (NC) Operation

What it means: The valve stays shut with spring force when not powered — opens only when 12V is applied.
Why it matters: Fail-safe — loss of electrical power automatically stops water flow, preventing flooding.
Result: Intrinsic safety in unattended or remotely-controlled water systems.

2. Low 6.5W Power Consumption

What it means: Draws approximately 0.54A at 12VDC — modest power that can run from small power supplies or battery systems.
Why it matters: Minimal heat generation during continuous-duty applications; suitable for solar or battery-powered installations.
Result: Energy-efficient operation over extended duty cycles.

3. 6.5mm Barbed Inlet

What it means: 6.5mm outer-diameter barbed connection for flexible tubing push-on installation.
Why it matters: Quick connect/disconnect without threaded fittings — common in appliance manufacturing for rapid assembly.
Result: Easy field replacement with standard flexible tubing and hose clamps.

Key Specifications

Typical Applications

• Coffee and Espresso Machines: Controlling water inlet to boilers and brew groups in commercial and super-automatic machines.
• Ice Makers: Filling ice tray reservoirs in commercial ice production equipment.
• Laboratory Water Systems: Automated filling and dispensing in analytical instrument sample preparation.
• Humidification Systems: Controlling water supply to evaporative pads and misting nozzles in HVAC and greenhouse applications.

Frequently Asked Questions

"What is the minimum and maximum water pressure for this valve?"

Solenoid inlet valves of this type typically operate from 0 to 1.0 MPa (0-10 bar). Verify the exact pressure range from the product label. Too little pressure and the valve may fail to seal fully when closed; too much and the solenoid may not have enough force to open against the water pressure.

"Can this valve be used with hot water?"

Verify the temperature rating from the product label or datasheet. Standard solenoid water valves are typically rated for cold water up to 60 degrees Celsius. For hot water or steam applications, a high-temperature valve with appropriate seal materials (EPDM, PTFE, or Viton) is required.

"How do I prevent water hammer when this valve closes?"

Rapid solenoid valve closure can cause water hammer in rigid plumbing. Install a small expansion chamber or water hammer arrestor downstream of the valve. Alternatively, use flexible tubing connections that absorb the pressure spike naturally. Avoid long straight rigid pipe runs immediately downstream.
