Assembly Build Process

Sun's Assembly Build Process allows you to configure a cartridge and manifold, or main stage and pilot stage cartridge, and build a digital assembly in three dimensional space. The resulting output of this process is the assembly product page, including configuration-specific images, symbols, product information and CAD files for download.

The Assembly Build Process can be accessed from either a cartridge or manifold product page. Only valid choices are allowed.

From a manifold page, you must first choose your cartridge function. Once you choose your function, click on the BUILD ASSEMBLY button below the WHERE TO BUY BUTTON. Once clicked, you will be presented with valid cartridges for your manifold. Select the cartridge of your choice and follow the instructions at the top of the page. If your particular combination has been generated before, the resulting assembly page will be available immediately. If not, you will be asked to enter your email address. Once the page is complete, an email will be sent to you including a link to the assembly product page.

From a cartridge product page, click on BUILD ASSEMBLY and you will be presented with a listing of compatible manifolds. In the case of main stage and pilot stage cartridges, you can either build a cartridge to cartridge assembly or a cartridge to manifold assembly. Once your choice has been made, follow the instructions at the top of the page. If your particular combination has been generated before, the resulting assembly page will be available immediately. If not, you will be asked to enter your email address. Once the page is complete, an email will be sent to you including a link to the assembly product page.

Please note that the Assembly Build Process is an automated process. It can be utilized at any time. Pages are generated typically within minutes but delays can occasionally be expected. In the event of a delay, a team at Sun will work to resolve the issue to ensure you receive your information as quickly as possible.

Direct-acting relief valve, 6000 psi (420 bar) - common cavity

Capacity: 10 gpm40 L/min. | Cavity: SC-10-02

Expand All

Technical Features [ + ]

This direct-acting relief cartridge is a normally closed, pressure-limiting device used to protect hydraulic systems from over pressurization. When the pressure at the inlet (Port 1) reaches the valve setting, the valve opens to tank (Port 2) to prevent over pressurization. This valve is dirt-tolerant and is designed to be very fast-acting with a low rate of pressure rise, but at the expense of smoothness.

Available in Daman D03 and D05 standard manifolds. Click Here! for more information.
The cartridge installation torque of 44 lbf ft (60 Nm) is required for best performance.
Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio and should be limited to tank pressure.
Not suitable for use in load holding applications.
The adjustment mechanism under the tamper resistant cap can be fully uninstalled while the valve is in the cavity. This will expose system fluid to the atmosphere. Care should be taken when adjusting the valve setting while installed. The setting procedure is: check the setting, remove the pressure, adjust the valve, check the new setting.
These valves come with standard settings established at the factory. Any setting adjustments not carried out by the factory should adhere to the valve's setting procedure. We will consider custom settings, set at the factory, on an individual basis. To submit your custom requirements, please use the 'New Product Ideas' link found under the 'Contact' tab.

FAQs [ + ]

What are the tolerances on pressure settings for Sun's pressure control valves?

Pressure setting tolerances are listed in our Performance Data page. A link to this page can also be found in the Additional Resources tab of the applicable product page.

How big is a drop of hydraulic oil?

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.

Can I use a kick-down relief for my system relief?

Maybe not. We build in a good amount of overlap in the kick-down reliefs to prevent false tripping. This means they are not as fast as our standard pilot-operated reliefs. A direct-acting relief valve set just above the kick-down relief valve would be good insurance.

Direct acting or pilot operated - what do I use?

Direct-acting valves are used to prevent over pressure, and pilot-operated valves are used to regulate pressure. If you are unsure, use a direct-acting valve. Sun's direct acting valves are very fast, dirt tolerant, stable, and robust. Sun's pilot-operated valves are moderately fast, they have a low pressure rise vs. flow curve, and they are easy to adjust.

Where would I use a kick-down relief?

One graphic example is on a portable grain auger for silos. When the farmer gets caught in the auger the kick-down relief trips and allows him to escape.

What parts of the Sun cartridge valve are field serviceable?

Only external seals are serviceable. Sun offers replacement seal kits for all cartridge models. The applicable kit part number can be found in the product page's Technical Data table or by using our Cartridge Seal Kit search function located under Accessories. Please note: Converting the external seals from one material to another does not ensure fluid compatibility with that material due to the existence of internal seals within the cartridge.
