Proportional Pressure Control Valves, Reducing:Relieving

EHPR08-33 Proportional Reducing/Relieving Valve (EHPR08-33)

<div class="product-info group">
<div>
<h3>Product Operation</h3>
The EHPR08-33 allows free flow from ➀ to ➂ when no current is applied to the coil. When the coil is energized, ➁ is connected to ➀. Increasing current applied to the coil will increase the control (reduced) pressure proportionally. If pressure at ➀ exceeds the setting induced by the coil, pressure from ➀ is relieved to ➂Note: Back pressure on port ➂ becomes additive to the pressure setting at a 1:1 ratio.
</div>
<div>
<h3>Product Features</h3>
• 12 and 24 volt coils standard. 
• Optional manual override. 
• Industry common cavity. 
• Optional waterproof E-coils rated up to IP69K.

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>

A screw-in, cartridge-style, pilot-operated, spool-type reducing/relieving valve, which can be infi nitely adjusted across a prescribed range using a variable electric input. Pressure output is proportional to DC current input. This valve is intended for use as a pressure control device in demanding applications.



TS90-31 Proportional Reducing/Relieving Valve, (TS90-31)

<div>
<h3>Product Operation</h3>
Without applied current, the TS90-31 allows flow from 3 to 4 while blocking 2. When the coil is energized, 3 is connected to 2, and pressure at 3 is controlled pro-portional to the amount of current applied to the coil. If pressure at 3 exceeds the setting induced by the coil, pressure is relieved to 4. Back pressure on port 4 becomes additive to the pressure setting at a 1:1 ratio. 
Note: This product may be customized for special OEM performance characteristics. Consult factory.

TS12-36 Proportional Electric Reducing/Relieving (TS12-36)

<div>
<h3>Product Operation</h3>
The TS12-36 allows flow from ➁ to ➀ until pressure at ➀ equals the setting determined by the coil current. Port ➂ is typically connected to the reservoir. If external load increases the pressure at ➀ beyond this setting, pressure is relieved by allowing flow from ➀ to ➂. Minimum pressure at ➀ without any current is 100 psi.If external circuitry allows the pressure at ➁ to fall below the pressure at ➀, the valve will allow free flow from ➀ to ➁ regardless of the setting of the valve or the amount of current in the coil.

TS10-36 Proportional Electric Reducing/Relieving (TS10-36)

<div>
<h3>Product Operation</h3>
With current applied to the valve coil, the TS10-36 blocks flow from 2 to 1 until sufficient pressure is present at 1 to open the pilot section by offsetting the electrically induced solenoid force. Increasing electric current will increase the control (reduced) pressure at 1. With no current applied to the solenoid, the valve will relieve pressure at 1 at approximately 6,9 bar (100 psi), regardless of pressure at 2. 
The TS10-36 has an optional manual override feature. This allows the valve to be set when the electric supply is lost. The manual setting is added to the electric setting, so when using the manual override feature to establish a minimum setting, care is required to prevent the system from becoming over-pressurized.

A direct-acting, spool-type, drop-in-style, fl ange-mounted, pressure reducing/reliev-ing valve, which can be infi nitely adjusted across a prescribed range using a variable electric input. Pressure output is proportional to DC current input. The Ecoil is an integral part of the valve assembly, and cannot be replaced or fi eld-serviced.

EHPR98-T33 Proportional Reducing/Relieving (EHPR98-T33)

<div class="product-info group">
<div>
<h3>Product Operation</h3>
The EHPR98-T33 allows free flow from ➀ to ➂ when no current is applied to the coil. When the coil is energized, ➁ is connected to ➀. Increasing current applied to the coil will increase the control (reduced) pressure proportionally. If pressure at ➀ exceeds the setting induced by the coil, pressure from ➀ is relieved to ➂Note: Back pressure on port ➂ becomes additive to the pressure setting at a 1:1 ratio.

<h3>Product Features</h3>
• Economical drop-in style. 
• Integral waterproof coil standard. 
• 1000-hour salt spray protection. 
• 10, 12, 20 or 24 VDC coils. 
• Several push-on termination options.
