What are the seals made from?
What are the seals made from?
Santoprene. The manufacturer states these seals are fully resistant to chemicals and suited to both vacuum and pressure use.
What is the valve body and blade made from?
What is the valve body and blade made from?
The body is PVC, with a stainless steel blade and spindle, and a metal handle.
A PVC slide valve sized for 110mm (4 inch) solvent weld pressure pipework, suited to residential and commercial plumbing where you need dependable on/off control over flow. The sealed spindle and reinforced blade help keep shut-off reliable, reducing the risk of leaks developing at the top of the valve over time. Optional reducing sleeves, sold separately, let you adapt it to waste pipework too.
Overview This is a rigid PVC slide valve built for 110mm (4 inch) solvent weld pressure pipework, with a stainless steel blade and spindle, and sealing at the top that goes beyond a basic single O-ring design. It suits residential and commercial plumbing and drainage setups where you need to isolate a section of pipe or control flow into a tank. The multi-point sealing at the spindle helps keep the valve watertight where the handle passes through, so shut-off stays dependable each time you open and close it.
Key benefits The stainless steel blade and spindle are chosen for their resistance to corrosion, which keeps the slide mechanism moving freely rather than seizing up. Santoprene seals give the valve a rating for vacuum and pressure use, per the manufacturer's own specification, so it can go into both pressurised flow lines and vacuum-side applications. A metal handle offers a secure grip, so opening and closing the valve by hand doesn't take much effort.
You receive one slide valve, ready to join into your pipework. If you're connecting it to waste pipe rather than pressure pipe, you'll need the optional reducing sleeves separately, as these aren't supplied with the valve.
Choosing your size This valve is offered in one size, 110mm (4 inch), so check this matches your existing pipework before buying. It's built for solvent weld pressure systems as standard; for solvent weld waste pipework, add the optional reducing sleeves (sold separately) to adapt the fit.
