Burkert Type Solenoid Valve with Pivoted Armature | 178896 00227538 00271158

The high-performance Pivoted Armature Solenoid Valve series by Chengyuan Hydraulic is a precision component engineered to meet the industrial fluid control standards of Burkert. This range serves as a premium replacement for Burkert classic part numbers such as 178896 (typically Type 0330), 00227538, 00271158, and 00501234.

The core advantage of this series lies in its pivoted armature design, which provides total physical separation between the electromagnetic actuator and the fluid media. Chengyuan ensures 100% original-place interchangeability regarding mounting interfaces, electrical connections, and flow parameters. Every valve undergoes 100% leak testing and functional reliability testing before shipping, ensuring exceptional performance in corrosive environments and high-cycle applications.

Key Technical Advantages:

• Total Media Separation: A flexible diaphragm completely isolates the solenoid coil and moving parts from the fluid chamber. This prevents corrosive, viscous, or particle-laden media from damaging the internal core, dramatically extending service life in harsh chemical applications.

• Robust Pivoted Actuator: Unlike direct-acting valves, the pivoted structure offers superior vibration resistance and stronger return force. This design ensures highly precise and rapid shut-off even under zero differential pressure conditions.

• Low-Power/Low-Heat Design: Chengyuan has optimized the solenoid winding and magnetic conductivity, significantly reducing power consumption and heat generation. This is critical for controlling temperature-sensitive fluids and preventing overheating in compact cabinets.

• Universal Modular Mounting: Supports sub-base or manifold mounting. The compact body includes a manual override as standard, allowing for manual switching during commissioning or power failures.

Application Areas:

• Chemical Processing: Dosing and metering of acids, alkalis, and aggressive reagents.

• Water Treatment & Analysis: Automated sampling, filtration control, and bypass switching in water purification systems.

• Laboratory Equipment: Fluid circuit control in high-precision analytical instruments.

Expert Maintenance Tips:

• Electrical Verification: Always confirm the coil voltage (AC vs. DC) and power rating before replacement. AC models often have integrated rectifiers and are not interchangeable with standard DC units.

• Manual Override Reset: After commissioning, ensure the manual override knob is returned to the neutral “0” position. Failure to do so may prevent the solenoid from closing or opening the valve electronically.

• Crystallization Prevention: If the media is prone to crystallization, flush the circuit before system shutdown to prevent deposits on the pivoted seal, which could hinder the next startup.
