<h3>Product Operation</h3>
</div>
<div>
In its steady state, the ER10-S30 allows flow from ➁ to ➀ with the spring chamber constantly drained at ➂. On attainment of a pre-determined pressure at ➀, set by a (remote) pilot relief valve connected to port ➂, the spool shifts to restrict input flow at ➁, thereby regulating pressure at ➀
</div>
<div>
<h3>Product Features</h3>
• Adjustments cannot be backed out of the valve. 
• Adjustments prohibit springs from going solid. 
• Optional spring ranges to 207 bar (3000 psi). 
• Hardened spool and cage for long life. 
• Industry common cavity.

PR50-38 Pressure Reducing/Relieving Spool Valve (PR50-38)

<div>
<h3>Product Operation</h3>
In its steady state, the PR50-38 allows flow to pass bidirectionally from port 2 to port 1, with the spring chamber constantly drained at port 3. Upon attainment of a predetermined pressure at 1, the spool shifts to block flow at 2, thereby regulating pressure at 1. In this mode, the valve will also relieve from port 1 to port 3, at a variable value over the set reducing pressure. Tank port pressure is additive to the pressure setting at a ratio of 1:1.
</div>
<div>
<h3>Product Features</h3>
• Adjustments cannot be backed out of the valve. 
• Adjustments prohibit springs from going solid. 
• Optional spring ranges to 227.5 bar (3300 psi). 
• Optional 233 micron screen at port 2. 
• Industry common cavity.

A screw-in, cartridge-style, direct-acting, spool-type, hydraulic pressure reducing/relieving valve, with internal spring-chamber drain and spool damping chamber. It is designed to act as a pressure regulating valve for secondary circuits. Internal damping makes this valve particularly suitable for use in circuits with unstable input flows in demanding applications requiring enhanced stability.

PR58-38 Pressure Reducing/Relieving Spool Valve (PR58-38)

<div>
<h3>Product Operation</h3>
In its steady state, the PR58-38 allows flow to pass bidirectionally from port 2 to port 1, with the spring chamber constantly drained at port 3. Upon attainment of a prede-termined pressure at 1, the spool shifts to block flow at 2, thereby regulating pressure at 1. In this mode, the valve will also relieve from port 1 to port 3, at a user-specified value over the set reducing pressure. Tank port pressure is additive to the pressure setting at a ratio of 1:1.
</div>
<div>
<h3>Product Features</h3>
• Adjustments cannot be backed out of the valve. 
• Adjustments prohibit springs from going solid. 
• Optional spring ranges to 248 bar (4200 psi). 
• Optional 233 micron screen. 
• Hardened parts for long life. 
• Industry common cavity.

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 of 300 bar, which is achieved by the use of high specification materials. The centre adaptor where the unit is cased, is made using an advanced aluminium manifold die-casting process, eliminating porosity to give a lightweight assembly.
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>
</ul>
