The Sun Hydraulics PVHBLAN (PVHBLAN) is a ventable, pilot-operated pressure reducing/relieving valve designed to reduce a high primary pressure at the inlet to a constant reduced pressure at port 1, while also providing a full-flow relief function from port 1 to tank port 3. This valve features an additional vent port, port 4, which allows for remote control by pilot or two-way valves. The valve is constructed with Sun's floating style design to minimize internal binding due to excessive installation torque or machining variations. It operates with maximum pressures up to 5000 psi (350 bar) and accommodates a control pilot flow of 15-20 in\u00b3/min (0.25-0.33 L/min). The valve's adjustment can be modified through a clockwise turn mechanism that increases the setting over 5.5 turns. The PVHBLAN is equipped with EPDM seals, suitable for systems using phosphate ester fluids but not compatible with petroleum-based fluids, greases, or lubricants. The valve exhibits low deadband transition between reducing and relieving modes and maintains exceptionally flat pressure-flow characteristics for stable operation with low hysteresis. When reverse free flow is necessary from reduced pressure port 1 to inlet port 2, it is recommended to incorporate an additional check valve into the circuit as reverse flow may cause the main spool to close. The effective setting of the PVHBLAN can be controlled below the nominal value by adjusting the pressure at vent port 4. It has been factory-tested under blocked control conditions and offers various spring ranges with specific maximum differential pressures: ranges A, B are tested at up to 3000 psi (210 bar), D, E at up to 2000 psi (140 bar), and W at an inlet pressure of up to 5000 psi (350 bar).

Ventable, pilot-operated pressure reducing/relieving valves reduce a high primary pressure at the inlet to a constant reduced pressure at port 1, with a full-flow relief function from port 1 to tank (port 3). The vent port (port 4) can be used as a means for remote control by pilot or 2-way valves.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 3000 psi (210 bar).
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Pilot operated valves exhibit very low dead-band transition between reducing and relieving modes.
- Recommended maximum inlet pressure is determined by the adjustment range. Ranges D, E, N, and Q are tested with a 2000 psi (140 bar) maximum differential between inlet and reduced pressure. Ranges A, B, and H are tested with a 3000 psi (210 bar) maximum differential between inlet and reduced pressure. Ranges C and W are tested with 5000 psi (350 bar) of inlet pressure.
- Pilot operated valves exhibit exceptionally flat pressure/flow characteristics, are very stable and have low hysteresis.
- 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.
- By controlling the pressure at the vent (port 4), the effective setting of the valve can be controlled below the nominal valve setting.
- 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.
