Product Questions & Answers

Got a refuse hauler that needs a reliable check valve rated for 5000 psi. This the one?

Question by: Bobby C on Apr 9, 2025, 8:44 PM

For a refuse hauler running at that pressure, the 4SK1403S3 fits right in. It's rated to 350 bar, which works out to 5000 psi, and it handles up to 140 litres per minute of flow. The poppet-style design gives you positive sealing so you're not dealing with backflow creep under load. It's actually listed for refuse hauler applications specifically, so you're in the right place with this one.
