The Primaflow 42mm Gate Valve is an essential plumbing component designed for professional plumbers and DIY enthusiasts needing reliable flow control in 42mm piping systems. Its primary benefit is the ability to isolate specific sections of a water circuit, allowing for targeted maintenance or repair without the necessity of draining the entire domestic system. While it provides a robust seal, users should note that as a gate valve, it is intended primarily for fully open or fully closed positions rather than fine-tuned flow regulation.

This valve is designed specifically for water supply systems and should not be used for gas applications.
No, this is a compression valve, meaning it uses nuts and olives to create a seal, removing the need for heat or solder.
While not strictly necessary for compression fittings, a small amount of plumbers' tape or sealant on the threads can provide extra security, though the seal is primarily made by the olive.
Yes, this gate valve can be installed vertically or horizontally, though it is usually best practice to ensure the handwheel remains easily accessible for future maintenance.
It is rated for standard domestic water pressures; please consult your local plumbing regulations if you are dealing with unusually high-pressure systems.
Ensure the pipe is cut squarely and the olive is seated correctly; tighten the compression nut slightly further.
Check for mineral deposits or debris; if persistent, ensure there is no excessive pressure on the valve body from misaligned pipes.
Verify that the handwheel is tightened fully; if the problem persists, the internal gate seat may be obstructed by debris.
Installation requires standard pipe-fitting tools, specifically adjustable wrenches to tighten the compression nuts. Ensure the 42mm pipe is cut squarely and deburred to prevent damage to the olive. Slide the nut and olive onto the pipe, insert the pipe into the valve body, and tighten the nut firmly by hand followed by a quarter to half-turn with a wrench. Over-tightening can deform the olive, so apply pressure gradually. Care should be taken to support the weight of the pipe on either side of the valve to prevent mechanical strain. Periodically operate the valve fully open and closed once a year to prevent mineral build-up and ensure the internal gate mechanism remains free-moving.
