Pilot-Operated Check Valves, Lock Valves

DC08-40 Pilot Operated Check Valve (DC08-40)

<div>
<h3>Product Operation</h3>
The DC08-40 will block flow from 1 to 2, and from 4 to 3. Flow is allowed in the opposite direction when pressure is applied to port 2 and/or port 3. 
The valve has a 3:1 pilot ratio, so at least 1/3 of the load pressure at port 1 or 4 is required at the pilot lines (ports 2 or 3) to open the flow passage to allow flow from ports 1 or 4. 
The check is spring-biased at 25 psi to assure holding in a static or no load condition. An optional spring biased at 135 psi is available. 
Note: Orifice disc cannot be used with this product.
</div>

<h3>Product Features</h3>
• Hardened seat for long life and low leakage. 
• Low pressure drop.

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>

<h3>Product Operation</h3>
The PC10-38 allows flow from ports 2 to 3, while blocking flow in the opposite direc-tion. If the presure at port 3 exceeds the thermal relief setting, a small amount of oil will be allowed to pass from port 3 to port 2, preventing cylinder damage from pres-sure intensification.

A screw-in, cartridge-style, pilot-operated, hydraulic check valve for use in blocking or load-holding circuits. Pilot ratio is 3:1. The cartridge incorporates a low flow thermal relief valve intended to prevent cylinder damage resulting from temperature-induced pressure intensification. Note: The thermal relief feature is not intended for use in dynamic pressure-limiting applciations.

PC10-32 Check, Pilot-to-Open, 2:1 Pilot Ratio (PC10-32)

<div class="product-info group">
<div>
<h3>Product Operation</h3>
The PC10-32 allows flow passage from ➁ to ➂, while normally blocking flow from ➂ to ➁. Flow will be allowed from ➂ to ➁ when pressure is applied at ➀The cartridge has a 2:1 pilot ratio, meaning that at least one-half of the load pressure 
held at ➂ is required at ➀ to open the valve.The check is spring-biased to assure holding in static or no-load conditions. 
A sealed pilot piston option is available.
