Piloted, 3-Way Spool Valves, Vented

PD12-40 Piloted 3-Way Spool, External Vent (PD12-40)

<div class="product-info group">
<div>
<h3>Product Operation</h3>
In neutral (unpiloted), the PD12-40 allows flow from ➂ to ➁ bidirectionally, while flow is blocked at ➃. V is a spring chamber vent-to-atmosphere, which is internally O-ring sealed from the cartridge flow paths. 
On remote pilot signal at ➀, the valve shifts to open from ➂ to ➃, while blocking flow at ➁Because of the vented spring chamber, the cartridge may be fully pressurized at any 
port without affecting required pilot pressure.

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>

PD42-M40 Piloted 3-Way Spool, External Vent (PD42-M40)

<div>
<h3>Product Operation</h3>
In neutral (unpiloted), the PD42-M40 allows flow passage from ➂ to ➁ bidirectionally, while flow is blocked at ➃. V is a spring chamber vent-to-atmosphere, which is internally O-ring sealed from the cartridge flow paths. 
On remote pilot signal at ➀, the valve shifts to open from ➂ to ➃, while blocking flow at ➁The vented spring chamber allows PD42-M40 to be fully pressurized at any port 
without affecting required pilot pressure.
