The Primaflow 15mm Gate Valve (302209) is an ideal solution for plumbers and homeowners seeking reliable flow isolation for cold water feeds, tank supplies, and central heating circuits. Its primary benefit is the full-bore design, which minimizes pressure loss by allowing the gate to lift entirely out of the water path when fully open. One important caveat is that this valve is designed for use specifically in either the fully open or fully closed position, rather than for throttling or regulating flow, to ensure the internal seal maintains its integrity over time.

No, this is an isolation valve designed to be either fully open or fully closed. It is not designed for throttling flow.
Yes, it is designed for cold feeds, tank supplies, and general heating circuits, which includes domestic hot water pipework.
A full-bore valve allows the internal gate to pull completely out of the pipe diameter, ensuring zero flow restriction and no pressure drop.
The rising wheel head moves vertically as you turn it; when the wheel is at its highest position, the valve is open.
Yes, but it is generally recommended to install it in a position that allows easy access to the wheel handle for future operation.
Apply a small amount of penetrating lubricant to the valve spindle and gently work the handle back and forth to loosen deposits.
Check the packing nut under the handle and tighten it slightly clockwise to compress the seal.
Ensure the handle is turned until it physically stops; if it still leaks, there may be debris caught under the gate requiring a temporary flush.
This 15mm valve is compatible with standard 15mm copper or compatible plastic piping systems. During installation, ensure the valve is oriented correctly according to the directional flow markings if applicable. Use appropriate jointing compounds or PTFE tape as required by your specific piping material. For maintenance, it is recommended to cycle the valve (open and close it) at least once or twice a year to prevent mineral deposits or debris from seizing the internal mechanism. Do not overtighten the handle, as this can strain the internal gate spindle over time.
