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.

Manual Hydraulic Hand Pump with Dual Integrated Check Valves

The manual hydraulic hand pump, HPUA, is one of the newest featured products in the Sun Common cartridge cavity family. Featuring dual integrated check valves, this product ensures optimal flow control and prevents backflow. The lever socket can rotate 360°, allowing for easy and convenient operation. The HPUA is rated to 3000 psi (210 bar), and is constructed with zinc plating to ASTM specifications for 240 hours of salt spray resistance, making this valve capable to withstand harsh environments.
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.

2-way, 2- position solenoid-operated, direct acting, balanced spool directional valve
The DLUT is a solenoid-operated, direct-acting, 2-way, 2-position balanced spool directional valve that is offered in an SC-10-02 cavity and a normally closed configuration. This bi-directional valve has a preferred flow path of 2 to 1. No minimum hydraulic pressure is required for the operation of the valve. The DLUT is compatible with the 780 Series coils. The valve offers great functionality and can serve as an optimal solution for sweepers or other industrial hydraulic machines with maximum pressures less than 3000 psi (210 bar).
