Sun Hydraulics offers 2-, 3- and 4-port flow control cartridges for metering and flow regulation. Sun flow control options include:
- Electro-proportional throttle valves
- Needle valves with or without free flow check
- Fully adjustable needle valves
- Pressure compensated valves
- 3- and 4-port priority flow controls
Fully Adjustable Needle
- Maximum operating pressure = 5000 psi
- Maximum valve leakage at shutoff = less than 5 drops/min.
Fully Adjustable Needle, High Capacity
- Maximum operating pressure = 5000 psi
- Maximum valve leakage at shutoff = less than 5 drops/min.
Fully Adjustable Needle with Reverse Flow Check
- Maximum operating pressure = 5000 psi
- Maximum valve leakage = 5 drops/min.
Fixed Orifice, Pressure Compensated
- Maximum operating pressure = 5000 psi
- Customer must specify flow setting
- Accurate pressure compensated control requires that a 200 psi minimum pressure differential be maintained across the valve.
- The tuneable control option provides +/- 25% variation from the nominal factory pre-set flow.
Fixed Orifice, Pressure Compensated with Reverse Flow Check
- Maximum operating pressure = 5000 psi
- Customer must specify flow setting
- Accurate pressure compensated control requires that a 200 psi minimum pressure differential be maintained across the valve.
- The tuneable control option provides +/- 25% variation from the nominal factory pre-set flow.
Fully Adjustable Pressure Compensated with Reverse Flow Check
- Maximum operating pressure = 5000 psi
- Accurate pressure compensated control requires that a 200 psi minimum pressure differential be maintained across the valve.
Free Flow Side-to-Nose with Bypass Orifice
- Maximum operating pressure = 5000 psi
- Will accept 5000 psi at ports 1 and 2.
- * Orifice range = CNAC, CNCC: 0.015 – 0.062 in., CNEC: 0.015 – 0.078 in., CNGC: 0.015 – 0.094 in., CNIC: 0.015 – 0.125 in.
Electro-proportional, Normally Closed Throttle
- Maximum operating pressure = 5000 psi
- Maximum valve leakage = 6 in³/min. at 3000 psi
- For optimum performance, an amplifier with current sensing and adjustable dither should be used.
- Dither should be adjustable between 100 – 250 Hz.
Electro-proportional, Normally Open Throttle
- Maximum operating pressure = 5000 psi
- Maximum valve leakage = 6 in³/min. at 3000 psi
- For optimum performance, an amplifier with current sensing and adjustable dither should be used.
- Dither should be adjustable between 100 – 250 Hz.
