Water valve Sourcing C322N10QB — 1in x 1/2in, 2-way, cold water

Sourcing C322N10QB is a compact 2-way water valve engineered for cold water systems. With inlet and outlet connection sizes of 1 inch and 1/2 inch, the valve is intended to control flow in residential and commercial plumbing installations, repairs and system upgrades where a small two-port shutoff or control valve is required.

Advantages

The valve provides a simple, space-efficient solution for controlling cold water flow. Its two-way design allows reliable on/off or proportional control in line with common plumbing layouts. The differing inlet and outlet diameters make it adaptable to transition points between pipe sizes without bulky adapters, and its compact form factor supports installation in confined spaces such as service cabinets, behind fixtures, or inside distribution manifolds.

Suitable for

• Residential cold water lines (sink, toilet, shower shutoffs)
• Commercial plumbing where a compact 2-port control is needed
• Repair and replacement of valves with 1" to 1/2" connections
• System upgrades where pipe diameter reduction or transition is required

When it may not be suitable

This valve is designed specifically for cold water applications and should not be used with hot water systems unless the manufacturer confirms temperature compatibility. It is not intended for use with gases, chemicals, or high-pressure industrial fluids. For installations requiring full bore flow rates equal to the larger inlet size, or for applications demanding three-way flow paths or mixing functions, a different valve type will be required.

Key specifications

• Valve type: 2-way (two-port) control valve
• Suitable medium: cold water
• Connection sizes: 1 inch inlet × 1/2 inch outlet
• Typical applications: plumbing shutoff, flow control, pipe size transition
• Form factor: compact inline valve for confined installations

How to use

Install the valve in-line with the cold water supply following local plumbing codes and standard installation practices. Ensure the flow direction matches the valve orientation if marked, and use appropriate sealing methods (thread tape or sealant) compatible with potable water. Tighten connections to manufacturer-recommended torque to avoid leaks or damage. Operate the valve handle or actuator to open or close the flow; if a tool is required, use the correct size to prevent damage to the control mechanism.

What to consider before purchase

• Confirm required connection orientations and pipe sizes at the installation point
• Verify suitability for cold water only and check temperature/pressure limits with installer or product literature
• Assess space constraints to ensure the compact valve will fit the installation area
• Check compatibility with existing fittings and whether adapters or additional seals are needed

Usage recommendations

For long service life, avoid exposing the valve to temperatures or pressures beyond the recommended range and perform periodic inspections for leaks. During installation, follow local plumbing regulations and, when in doubt, consult a licensed plumber to ensure proper fitment and safe operation.
