Product Information

Full details

The Primaflow 2-inch gate valve is an essential component for professional plumbers and experienced DIY enthusiasts who need a reliable method for isolating water supply lines. Its primary benefit is the ability to shut off water to a specific branch or the main line, allowing for repairs and maintenance without needing to drain the entire building's plumbing system. Please note that this is a full-bore gate valve designed for isolation purposes, and it is not intended for flow regulation or throttling water pressure.

Extended Product Information

FAQs

Can I use this valve to regulate water pressure?

No, this is a gate valve designed specifically for fully-open or fully-closed operation. Using it in a partially open position may lead to vibration, noise, and erosion of the gate.

Is this valve suitable for central heating systems?

Yes, the brass construction is compatible with most standard residential and commercial heating systems.

What does BSP stand for?

BSP stands for British Standard Pipe, which is the standard thread type used for plumbing fittings in many parts of the world.

Does it matter which way the water flows through the valve?

Gate valves are generally bidirectional, meaning they can be installed with flow moving in either direction.

How do I know if the valve is fully open?

Turn the handwheel counter-clockwise until you feel it stop. Do not apply excessive force once it hits the stop.

Troubleshooting

Valve leaking from the spindle nut

Gently tighten the packing nut located beneath the handwheel to compress the internal seal.

Valve handle is difficult to turn

Apply a silicone-based lubricant to the spindle threads and gently work the handle back and forth to loosen mineral buildup.

Leakage at the pipe connections

Check that sufficient PTFE tape was used; if not, unscrew the connection, clean the threads, re-apply sealant, and tighten again.

Pros and Cons

Pros

  • Extremely durable brass construction
  • Easy to install with standard BSP threading
  • Effective isolation of water branches
  • Full-bore design prevents flow restriction

Cons

  • Not suitable for throttling or adjusting flow rate
  • Requires significant clearance for handle operation
  • Brass can be heavy and requires proper support in vertical pipe runs

Setup, Compatibility & Care

Installation requires standard plumbing tools, including large pipe wrenches and high-quality thread sealant or PTFE tape to ensure a watertight seal on the BSP threads.

  1. Ensure the pipe ends are clean and free of debris.
  2. Apply thread sealant to the male threads of your pipework.
  3. Carefully thread the valve onto the pipe by hand to avoid cross-threading.
  4. Tighten using pipe wrenches, taking care not to overtighten and crack the brass body.
  5. Test for leaks by slowly pressurizing the system.

For ongoing care, cycle the handle once every six months to prevent the accumulation of scale or mineral deposits that could cause the valve to seize over time.
