Question by: Steve R on Jan 14, 2026, 3:14 PM
Reckon this check valve would hold up okay on a refuse hauler? Those things take a beatin'.

Designed for demanding industrial environments, the Vickers 4CK30 series is well-suited for mobile applications like refuse haulers, offering reliable performance under high pressure.
Question by: Warren H on Dec 12, 2025, 4:57 PM
What kind of pressure can this check valve actually hold up to, and is it built for heavy-duty equipment like harvesters?
Answer by: Customer Support on Dec 14, 2025, 1:55 PM
Rated at 350 bar, which works out to 5000 psi, it's well within the range for demanding equipment like harvesters and refuse haulers. The poppet style construction gives it solid sealing under those pressures, and the low spring settings help keep fluid control consistent even in tough working conditions.
