The Sun Hydraulics PRDNXEN2C24V (Material Number: PRDNXEN2C24V) is an electroproportional, direct-acting reducer-reliever valve designed to reduce high primary pressure at inlet port 2 to a constant reduced pressure at port 1, while offering a full flow relief function from port 1 to tank port 3. This valve is biased towards the reducing mode, allowing connection from port 2 to port 1 at a specified pressure setting. By increasing the current to the coil, the reduced pressure at port 1 decreases proportionally. Should the pressure at port 1 exceed the coil-induced setting, it will be relieved to port 3. Notably, this transition between reducing and relieving modes is closed, resulting in minimal oil consumption and leakage. The maximum allowable pressure at port 3 is limited to 3000 psi (210 bar), with pressure being directly additive to the valve setting in a 1:1 ratio. For optimal performance, it is recommended that an amplifier with current sensing and adjustable dither between 100-250 Hz be used. The valve's coils are interchangeable with other Sun solenoid-operated valves and can be mounted in either direction on the tube. When there is no electrical signal, the reduced pressure defaults to a customer-specified value. This valve is suitable for accumulator circuits due to its design that minimizes secondary circuit leakage by eliminating pilot control flow. The PRDNXEN2C24V features Sun's floating style construction which reduces internal part binding risks due to excessive installation torque or machining variations of cavity/cartridge interfaces. It supports up to a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 5 gpm (20 L/min). Its robust design ensures reliable operation even in contaminated systems or dead-headed conditions.

This electro-proportional, direct-acting reducer/reliever valve reduces a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, with a full flow relief function from port 1 to tank (port 3). The valve is biased to the reducing mode, connecting port 2 to port 1 at a customer specified pressure setting. Increasing the current to the coil will proportionally decrease the reduced pressure at port 1. If pressure at port 1 exceeds the setting induced by the coil, pressure at port 1 is relieved to port 3. This valve is closed in the transition between reducing and relieving resulting in very low consumption of oil.

  • Maximum pressure at port 3 should be limited to 3000 psi (210 bar).
  • Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 3000 psi (210 bar).
  • Leakage specified in Technical Data is out of port 3 with a supply pressure of 2000 psi (140 bar) and the valve set at mid range. This leakage is directly proportional to pressure differential and inversely proportional to viscosity expressed in centistokes.
  • The transition from reducing to relieving is closed. The result is very low leakage. However, there is a transitional step increase in pressure between reducing and relieving modes. This step equals about 5% of the high end of the adjustment range, independent of the valve setting.
  • For optimum performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable between 100 - 250 Hz.
  • Coils are interchangeable with Sun's other full flow, solenoid-operated valves and can be mounted on the tube in either direction.
  • With no electrical signal, the reduced pressure setting will default to the customer specified value. Increasing the command to the coil will proportionally reduce the secondary pressure value.
  • Suitable for accumulator circuits since the absence of pilot control flow results in reduced secondary circuit leakage.
  • Direct acting concept provides highly reliable operation in contaminated systems, especially at dead headed conditions.
  • Full reverse flow from reduced pressure (port 1) to inlet (port 2) may cause the main spool to close. If reverse free flow is required in the circuit, consider adding a separate check valve to the circuit.
  • All three-port pressure reducing and reducing/relieving cartridges are physically interchangeable (i.e. same flow path, same cavity for a given frame size). When considering mounting configurations, it is sometimes recommended that a full capacity return line (port 3) be used with reducing/relieving cartridges.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
