HydraForce RV58-20 Relief Valve

The HydraForce RV58-20 is a screw-in, cartridge style, direct acting, poppet type, hydraulic relief valve intended for lower flow circuits, requiring low internal leakage.

The RV58-20X blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to force the spring opposed poppet from its seat.

Key features include:

• Rated for higher operating pressure of 345 bar (5000 psi).
• Bi-directional pressure option available.
• Adjustments cannot be backed out of the valve.
• Adjustments prohibit springs from going solid.
• Variety of adjustment options available.
• Rapid response to pressure changes.
• Compact size.

Pressure ratings:

• Pressure rating: 344.7 bar (5000 psi)
• Proof pressure: 517.1 bar (7500 psi)
• Burst pressure: 1294.4 bar (18774 psi)
• Relief pressure defined: pressure evident at 0.95 lpm (0.25 gpm)

Flow rating: 22.7 litres / minute (6 gallons / minute)

This valve can be used with mineral based or synthetic hydraulic fluid with lubricating properties.
