Sun Hydraulics offers many small solenoid and non-solenoid pilot valves that can be used to provide directional pilot control. Pilot controls that feature a T-8A cavity can also be directly installed into the hex end of many of Sun’s pilot operated and ventable cartridges to provide integrated pilot control. Pilot offerings include:
- 2-way and 3-way 5000 psi (350 bar) solenoid cartridges
- Hydraulically operated 2-positon, 2-way and 2-position, 3-way pilot cartridges
- Air piloted 2-position, 2-way and 2-position, 3-way pilot controls
- Manually operated, 2-position, 2-way, intermittent pilot control
2-position 2-way, Spool Directional Valve – Pilot Capacity
- Maximum operating pressure = 5000 psi
- Maximum leakage at 150 SUS = 10 drops/min. at 5000 psi
- Switching frequency = 15000 cycles/hour
- Cartridge can be installed directly into a cavity in some Sun pilot operated and ventable cartridges to provide electrically operated pilot control functions.
- Proper installation of solenoid valves requires an extra deep socket to clear the solenoid tube.
- Sockets are available from Snap On tools (P/N SIML280) or Sun Hydraulics (P/N 998-100-006).
Hydraulically Operated, 2-position 2-way, Spool Directional Valve – Pilot Capacity
- Maximum operating pressure = 5000 psi
- Maximum leakage at 150 SUS = 10 drops/min. at 5000 psi
- Minimum pilot pressure to operate = 200 psi
- All ports will accept 5000 psi including the pilot control port.
- The preferred flow path through the valve is port 2 to port 1.
- The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required torque value.
Air-operated, 2-position 2-way, Spool Directional Valve – Pilot Capacity
- Maximum operating pressure = 5000 psi
- Maximum leakage at 150 SUS = 10 drops/min. at 5000 psi
- Maximum pilot pressure = 70 psi
- Minimum pilot pressure to operate = 20 psi + port 1 pressure/100 psi
- All ports will accept 5000 psi with the exception of the pilot port which accepts 500 psi maximum.
- The preferred flow path through the valve is port 2 to port 1.
- The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required torque value.
Manually Operated, 2-position 2-way, Spool Directional Valve – Pilot Capacity
- Maximum operating pressure = 5000 psi
- Maximum leakage at 150 SUS = 10 drops/min. at 5000 psi

Direct Acting, Adjustable Pilot Relief
- Maximum operating pressure = 5000 psi
- Maximum leakage = 5 drops/min. at reseat (reseat = 85% of cracking pressure).
- Ports 1 and 2 may be pressured to 5000 psi.
- Back pressure at port 2 (outlet) is directly additive to the pressure setting at port 1 (inlet).
- The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required torque value.
Air-controlled, Directing Acting Pilot Relief
- Maximum operating pressure = 5000 psi
- Maximum leakage = 5 drops/min. at 5000 psi
- Maximum pilot pressure = 150 psi
- Ports 1 and 2 may be pressured to 5000 psi.
- Back pressure at port 2 has no effect on the valve setting.
- The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required torque value.
Fully Adjustable Needle Valve – Pilot Capacity
- Maximum operating pressure = 5000 psi
- Maximum leakage at shutoff = less than 5 drops/min. at 5000 psi
- Effective orifice size = 0.035 in.
- Number of counterclockwise turns fully closed to fully open = 3
- Ports 1 and 2 may be pressured to 5000 psi.
Electro-proportional Pilot Relief
- Maximum operating pressure = 5000 psi
- Maximum leakage = 1.5 in³/min at reseat
- Back pressure on the tank port (port 2) is directly additive at a 1:1 ratio to valve setting
- Reseat exceeds 85% of cracking pressure.
- Hysteresis with dither <4%
- Hysteresis with DC input <8%
- Linearity with dither <2%
- For optimum performance, an amplifier with current sensing and adjustable dither should be used.
- Dither should be adjustable between 100 – 250 Hz.
