Full Bore Lever Ball Valve C/W Red & Blue Bands - 15mm

Full Bore Lever Ball Valve C/W Red & Blue Bands - 15mm

The 15mm Full Bore Lever Ball Valve is a high-quality isolation valve designed for use in domestic and commercial plumbing and heating systems. This specific model features a black lever handle supplied with interchangeable red and blue indicator bands, allowing you to clearly identify hot or cold water lines.

The "Full Bore" design ensures that the internal diameter of the ball matches the pipe size, providing unrestricted flow and minimal pressure drop.

Key Technical Specifications

Size: 15mm Compression ends (suitable for copper pipe).

Bore Type: Full Bore (Maximum flow efficiency).

Operation: 1/4 Turn Lever handle.

Material: Chrome or Nickel-plated Brass body with a chrome-plated brass ball.

Max Temperature: Typically rated up to 120°C (depending on pressure).

Max Pressure: PN16 or PN25 (System dependent).

Approvals: Often WRAS approved for use with potable (drinking) water.

Why Use Lever Ball Valves?

Quick Isolation: The 1/4 turn mechanism allows for almost instantaneous shut-off in an emergency, unlike traditional gate valves that require multiple turns.

Visual Confirmation: You can tell at a glance if the valve is open or closed; the lever is parallel to the pipe when open and perpendicular when closed.

Durability: Ball valves are less prone to "seizing" over time compared to gate valves, making them more reliable for long-term isolation.

Installation Best Practices

Direction: While ball valves are generally bi-directional, it is best practice to install them so the lever points in the direction of flow when open.

Compression Joints: Ensure the copper pipe is cut square and deburred. Do not over-tighten the compression nuts; usually, a finger-tight turn followed by one full turn with a spanner is sufficient.

Color Coding: Fit the Red band for hot water/heating flow and the Blue band for cold water/mains supply during the final commissioning to assist future maintenance.
