Product Information
Full details
The Primaflow 22mm Gate Valve is an ideal choice for homeowners and professional plumbers looking for a robust, reliable mechanism to isolate water flow in domestic plumbing systems. Featuring a durable brass body and a high-visibility red handle, it is designed for applications where valves are used infrequently, such as maintenance shut-offs. While it offers excellent flow characteristics, users should note that gate valves are intended for fully open or fully closed positions and are not suitable for throttling or precise flow regulation.

FAQs
Can I use this valve to control the flow rate of a shower?
No, this is a gate valve designed only for fully open or fully closed operation. It is not suitable for throttling or regulating flow.
Does this valve work with plastic piping?
Yes, provided you use an appropriate pipe insert inside the plastic pipe to ensure the compression fitting maintains its shape and seal.
What is the maximum pressure rating?
The valve is designed to withstand standard domestic water pressure requirements; please consult local plumbing codes for specific pressure ratings in your region.
Can this valve be installed vertically or horizontally?
Yes, the valve can be installed in either orientation without affecting performance.
Do I need any specialized tools to install it?
No, you only need two adjustable spanners or wrenches to tighten the compression nuts.
Troubleshooting
Valve leaking at the compression joint
Tighten the compression nut slightly further. If it still leaks, disassemble, check that the pipe is square, and ensure the olive is not damaged.
Handle is stiff or difficult to turn
Mineral deposits may have built up. Gently work the handle back and forth to loosen the debris; avoid using excessive force which could damage the spindle.
Water continues to flow when valve is shut
The gate may be obstructed by debris. Cycle the handle several times to flush the seat, or check if the internal assembly is fully seated.
Pros and Cons
Pros
- Durable brass build ensures longevity
- Easy installation with compression fittings
- Provides unrestricted, full-bore flow
- Clear visual status with red handle
- Ideal for infrequent use
Cons
- Not suitable for throttling or regulating flow
- Larger footprint compared to ball valves
- Can be slower to actuate fully
- Requires proper tightening to ensure compression seal
Setup, Compatibility & Care
To install the valve, ensure the 22mm pipe ends are clean, square, and free of burrs. Slide the nut and compression olive over the pipe before inserting the pipe into the valve body. Tighten the nut firmly with a wrench to compress the olive against the pipe and the valve seating. Do not overtighten, as this can damage the fitting.
Compatibility: Designed specifically for 22mm outer diameter piping. Verify that your pipe material is compatible with standard compression fittings.
Care: To maintain smooth operation, cycle the handle from fully open to fully closed twice a year. This prevents the internal gate from seizing due to scale buildup or mineral deposits in hard water areas.
