VICKERS 3CA20-3.5S

Description & Features

Designed for mobile and industrial hydraulic circuits, the Vickers 3CA20-3.5S is a ball-style check valve from the 3CA20 Series, rated to 350 bar (5,000 psi) with a maximum flow capacity of 227 L/min (60 USgpm). This unit carries a flow rate of 40 litres per minute and features a low spring setting, which supports reliable backflow prevention with minimal pressure drop across the valve.

Well-suited for demanding mobile equipment including harvesters and refuse haulers, as well as stationary industrial hydraulic systems, the 3CA20-3.5S is built to maintain high operational efficiency across variable load conditions. The compact form factor, with a product width of 0.87, makes it compatible with tight installation envelopes typical of mobile machinery.

Question by: Rod R on Jul 29, 2025, 7:53 PM

What kind of machines does this valve work on? Looks like I need a replacement for a harvester.

Use-case-first: It's a good fit for harvesters, yes, along with refuse haulers and other mobile or stationary industrial hydraulic systems.

Question by: Chad B on May 3, 2025, 2:27 PM

Got a harvester that keeps dropping pressure on the return side, would a ball-style check valve like this one hold up for that kind of application?

Answer by: Customer Support on May 4, 2025, 5:04 PM

Ball-style check valves handle that kind of backflow prevention well in mobile equipment, and harvesters are actually a listed application for this valve. The low spring setting keeps pressure drop across the valve minimal, so you're not fighting the system just to move flow in the right direction. Rated to 350 bar (5,000 psi) and capable of handling up to 227 L/min (60 USgpm), it's got enough headroom for most harvester hydraulic circuits without becoming a restriction point.
