The 289 Series relief valves are spring-loaded throttling relief valves used downstream of pressure regulators to protect the downstream system from overpressure. A smooth throttling action minimizes pressure surges in the system during relief operation. The 289 Series relief valves are ideal for low-pressure settings due to the increased sensitivity provided by a large diaphragm area. The 289 Series relief valves are designed for pressure control; they are not ASME safety relief valves.

YUKEN MODULAR VALVES are designed to Simplify hydraulic systems, to eliminate the use of pipe connections and thus to save space, time and costs. The modular valves have standardized interfaces (lSO 4401. CETOP. NFPA) and thickness in accordance with each valve size. Any hydraulic circuit can be composed by stacking the modular valves in the correct sequence one upon another and bolting the various stacks to a common manifold base.
•Modular valves remarkably minimize the installing area and space.
• No expert skill is required to assemble, and furthermore, a supplement and a change to the circuit can easily and quickly be carried out.
• Problems such as oil leaks, vibration and noise resulting from pipes and tubes are minimized because pipes and tubes are not necessary.
•Checks and maintenance of these valves can be performed with ease because of the method of installation.

APPLICATION:
To control the flow of Water, Air, Gas, Solvents, Vacuum and any other fluids not reactive with construction materials and free of sediment. Buna N seating of the pilot and main orifices make the valves ideal for TIGHT SEATING, LOW PRESSURE and LOW FLOW conditions. Valve operates from zero to maximum differential pressure indicated in table. Valve must be mounted in horizontal pipe with solenoid enclosure vertical and on top.
OPERATION:
Valve closes when energized and opens when de-energized. When the coil is energized the plunger presses the poppet, closing the pilot orifice, and opens a bleed passageway to permit pressure to build above the piston and seat it. Upon de-energizing the coil, the pilot orifice is opened, relieving the pressure above the piston allowing it to leave its seat. The bottom spring allows the valve to operate at zero pressure drop.

The Brand, Series 83 is a two port, non-adjustable, pressure compensated, inline flow control, with free reverse flow. The amount of flow is determined by the diameter of the orifice in the compensator piston. The spring and piston are held in place when it is connected to an #8 SAE male fitting. This flow control is inexpensive and gives the customer the ability to change the flow rate by swapping the piston with another that has a different size orifice.

Continental Hydraulics PowrFlowTM Directional Control Valves offer some of the highest flow and pressure ratings in the industry today, making them the perfect choice whether you are designing a new system or just simply trying to get more out of your current system. Noted for superior performance and durability, Continental Hydraulics Directional Control Valves are a great investment.
With 12 standard spools, numerous specialty spools and 7 functions, these directional control valves can be ordered to meet the specific needs of your applications.
Precise bore honing and spool grinding results in less cross-port leakage and less wasted energy. These precision valves also allow for interchangeable spools for easy field maintenance and eliminate the need to change valve body when changing spools.
Spools utilize U-groove machining making them more tolerant of contaminants than v-groove designs resulting in less spool hang-ups. Bolt heads are below the spool centerline to reduce the body distortion that can lead to sticking spools and loss of production.
Control options include solenoid, lever, air, soft shift and cam operators.
All valves are 100% tested and come with a standard 3-year warranty.
Our CAD/CAM system takes the design directly from computer to high-speed CNC machining centers. Set ups are fast and multi-part designs are no problem. We can easily produce directional control valve variations for even greater flexibility. Click here to tell us what you need.
