Sun Common Cavity Cartridges Deliver
Excellent Solutions for your Application
We are proud to announce the launch of the Sun Common (SC) cavity cartridge valves. Joining the broad range of existing Sun Hydraulics cartridge valves, these new SC cavity cartridges are optimized for lower pressure systems.
These valves boast a common SAE style cavity, which is compliant to SAE cavity standard ISO 17209:2013. Several great options that will allow you to engineer optimized, interchangeable solutions and enhance the functionality of your demanding applications are available now.

Proportional pressure reducing and relieving, solenoid-operated cartridge valve

The PRTS is a proportional, direct-acting reducer/reliever that reduces a high primary pressure at the inlet port (Port 2) to a constant reduced pressure at Port 1, with relief function from Port 1 to tank (Port 3). Biased to relieving mode, this valve energizes the coil connection between Port 2 to Port 1. Rated to 3000 psi (210 bar) and featuring a nominal flow rate of 1 gpm (4 L/min), the PRTS consumes low levels of oil due to being closed in the transition between reducing and relieving.
