CR08-38 Bi-Directional Relief Valve, Vented (CR08-38)

<div>
The CR08-38 is a direct-acting, dual cross-over relief valve in a single cartridge format. It blocks flow from 1 to 2 bi-directionally, with the spring chamber constantly drained at 3. 
On attainment of a pre-determined pressure at either 1 or 2, the poppet is forced from its seat. Back pressure on port 3 will affect the nominal setting on a 2:1 basis. 
NOTE: If pressure is applied simultaneously at port 1 and port 2, the pressure isadditive and may cause the valve to shift at a pressure lower than the pre setpressure setting.
</div>
<div>
<h3>Product Features</h3>
• Adjustments cannot be backed out of the valve. 
• Adjustments prohibit springs from going solid. 
• Hardened parts for long life. 
• Industry common cavity.

CR10-28 Relief, Bi-Directional (CR10-28)

<div>
<h3>Product Operation</h3>
The CR10-28 is a direct-acting, dual cross-over relief valve in a single cartridge 
format. When pressure at either port exceeds the nominal setting value, flow will be 
transmitted to the opposite port. Back pressure at either port will affect the nominal 
setting of the opposite port on a 1:1 basis. 
For correlation purposes, pre-set value will be measured at port ➁. Pressure at port ➀ will not exceed ±150 psi from the port ➁ value.

Savery hydraulic power packs and mini power packs are the culmination of many years of experience in manufacturing AC and DC power packs.

Small HydraulicPower Packs

The PB300 series of power units offer the latest design and features not normally associated with this type of unit. The units have a pressure up to 300 bar, which is achieved by the use of high specification materials. The centre adaptor can be machined to give a vast range of integral control options for single and double acting circuits.
Applications for this type of unit are numerous DC units for battery powered use include our tail lift packs and can be found on tippers, aerial access equipment and material handling trucks. AC units with power ratings from 0.25kW to 5.5kW have an even greater range of applications including the retail and service industry for the handling of goods &#8211; loading and unloading of vehicles and the lift industry for lifts installed in the home, disabled lifts and automotive assembly plants.
Savery has developed hydraulic power packs specifically for applications such as dock levellers, which provide a bridge between the loading bay and the truck being loaded or unloaded.
PB300 units have;
<ul>
<li>DC units 12V &amp; 24V / 0.2 – 3.5kW.</li>
<li>AC units 3 Phase &amp; 1 Phase / 0.25 – 5.5kW.</li>
<li>A vast range of control options for single and double acting circuits.</li>
<li>Advanced pressure die-cast aluminium centre adaptor.</li>
<li>The ability to eliminate porosity.</li>
