The Burkert 468758 is a 2/2 way solenoid valve designed for automated fluid control in industrial applications. It offers reliable shut-off functionality for liquids and gases, operating efficiently with a 120V AC coil. A key benefit is its robust brass housing and FKM sealing, suitable for moderate to high temperatures and pressures. However, it requires a small differential pressure to operate, meaning it's not suitable for systems with zero pressure difference.

A Normally Closed (NC) valve is shut when not powered and opens when energized. A Normally Open (NO) valve is open when not powered and closes when energized.
No, the DIN connector for the electrical connection is not included with this valve and must be purchased separately.
This valve requires a minimum differential pressure of 0.2 bar (approximately 3 psi) to operate correctly.
It is suitable for neutral liquids and gases, such as water and air, provided they are within the specified temperature (-10 °C to 120 °C) and pressure (0.2 to 16 bar) limits. The FKM seals offer good compatibility.
No, this is an indirectly operated valve and requires a minimum differential pressure of 0.2 bar to function. It is not suitable for zero-pressure systems.
The Kv-value is 3.8 m³/h. For water at a differential pressure of 1 bar, this translates to a flow rate of approximately 63.35 liters per minute.
If the valve fails to actuate and power supply is confirmed, the coil may be faulty. Check for continuity and resistance values if specified by the manufacturer, or if it shows signs of overheating.
Verify the 120V AC power supply is correctly connected and energized. Check for a minimum differential pressure across the valve (at least 0.2 bar). Ensure the coil is properly wired and functional. Inspect for internal blockages.
Ensure power is completely removed from the coil. Check for debris preventing the valve seat from closing properly. Verify the differential pressure is not too high for the spring to overcome.
Tighten NPT connections using appropriate sealant. Inspect FKM seals for damage or wear and replace if necessary. Ensure the valve is not subjected to pressures or temperatures exceeding its specifications.
Check for unstable power supply voltage. Inspect electrical connections for corrosion or looseness. Ensure the differential pressure is within the operating range.
