high pressure hydraulic relief valve

Inline Pressure Relief valves are commonly used to set the correct pressure on hydraulic systems. · Good for protecting hydraulic motors on overrun in high 

The relief valves are also factory set for a specified cracking pressure (i.e. set pressure). When inlet pressure is reduced by 25% of set pressure, the relief valve reseals. The set pressure may be specified custom or standard ranging from 1250 to 5500 psi. Test reports may be supplied if requested.

Only after the system pressure has been reduced to a predetermined safe level will the relief valve close. Sargent’s experience with hydraulic systems provides a strong basis from which to support aircraft, spacecraft, and aerospace relief valve requirements. Sargent engineers routinely work with our customers to help define specifications if

High Pressure Equipment Company has developed a line of High Pressure products to assure safe and easy plum for 30,000, 40,000 and 60,000 psi. These needle valves, fittings, line filters, check valves, safety heads, rupture discs, anti-vibration gland assemblies, tu and nipples are engineered to the highest standards of repeatable quality.

Logan found some articles of AAK about the 450Bar high-pressure hydraulic valves on the B2B website, including 68HRC materials. He emailed the drawing of hydraulic relief valve directly to AAK and asked AAK for samples. After communication, we learned that the sample of this hydraulic relief valve was stuck on the material hardness.

Hydraulic Relief Valves. Northern Tool offers professional-grade adjustable relief valves that come ready to install and protect your hydraulic system from 

Fig. 18-15. NC solenoid relief valve used for high-flow bleed-off flow-control circuit. Shown at rest with pump running. Figures 18-15 through 18-16 show the schematic diagram for a high-flow, on-off, bleed-off flow control circuit. Set the solenoid relief valve higher than system pressure so it never passes fluid unless vented.

To inspect the valve 's components isolate the valve from voltage and fluid. Remove the top nut, I.D plate, coil and armature tube. Check for sediment, debris or corrosion inside the tube and valve body. Check that the armature/spring assembly moves freely inside the tube.

6/11 · These valves are smooth and quiet, low leak, dirt tolerant, immune to silting and are very fast. Features: • Factory set to user’s requested pressure relief up to 4000 psi (276 bar) • Inline valve will operate when mounted in any position in your hydraulic system. • Standard material is zinc plated steel or optional 316 stainless steel.
