Burkert Type 0450 Solenoid Valve 00162153 H 14.0 G1/2

The industrial-grade Burkert Type 0450 Series Heavy-Duty Pilot-Operated Piston Solenoid Valves, engineered by Chengyuan Hydraulic, are premium fluid control actuators designed for high-frequency switching, medium-to-high pressure cutting, and pneumatic/hydraulic pilot system regulation. This product profile specifically targets a high-demand, high-volume part identifier embedded extensively in global B2B industrial procurement and automation repair setups: BURKERT TYPE 0450 H 14.0 G1/2 24V (Order ID / Material Number: 00162153).

Utilizing an advanced pilot-operated piston framework, the Type 0450 solves the technical limitations that direct-acting solenoid valves encounter when operating under simultaneous large flow volumes and elevated fluid pressures. By leveraging the internal differential pressure of the medium itself to assist the primary piston stroke, it ensures smooth, energy-efficient shifting. Chengyuan’s premium replacement configuration guarantees 100% direct drop-in interchangeability with authentic German Burkert standards. Every critical dimension—including the total face-to-face body length, G 1/2 internal female thread standard, large internal orifice ($\phi 14.0\text{ mm}$), low-wattage 24V DC power draw, and standard DIN 43650 Form A plug terminals—aligns exactly with original blueprints, allowing seamless on-site replacements without altering existing PLC logic or physical plumbing arrays.

In automated processes, a sticking pilot component or internal fluid bypass directly triggers un-scheduled factory shutdowns, loss of loop pressure, or erratic actuator movements. Because the primary piston seal operates within a micro-tolerance sliding guide sleeve, fine pipeline contamination or continuous thermal cycles can trigger premature wear or mechanical sticking. To ensure field reliability, 100% of Chengyuan’s replacement solenoid valves undergo 100% strict dynamic simulation on digitized fluid test stands. Validated under full rated pressure differentials and variable flow speeds, every single valve is certified for ultra-precise response times (measured in milliseconds), coil thermal equilibrium under 100% ED duty cycles, and bubble-tight zero-leakage closure.

Key Technical Advantages

• PTFE Rider-Ring Friction-Reduction Piston System: The main piston assembly integrates a precision-turned carbon-filled PTFE rider ring. This advanced material matrix minimizes dynamic drag forces and completely eliminates metal-to-metal binding or valve sleeve scoring caused by poor fluid lubricity, ensuring consistent stroke performance.

• Low-Remanence Fast-Response Armature Core: The internal pilot armature components are ground from specialized soft-magnetic alloys characterized by high permeability and minimal residual magnetism. This ensures that under a 24V DC control signal, the valve registers an immediate response time of 20 to 40 milliseconds, eliminating lag times typical of standard pilot valves.

• Vacuum-Molded Epoxy Encapsulated Class H Coils: The coil assembly is wound with high-purity copper magnet wire on automated CNC machines and fully encapsulated using high-density epoxy resin under complete vacuum. The Class H thermal rating ($180^\circ\text{C}$) ensures excellent heat dissipation and shock resistance, maintaining zero insulation decay during continuous 100% ED (Continuous Duty) operation.

• CFD-Engineered Low-Turbulence Flow Paths: The internal valve cavity geometry is sculpted using 3D Computational Fluid Dynamics (CFD) simulation to eliminate sharp corners and turbulent dead zones. This structural enhancement yields a 12% increase in the Kv flow coefficient compared to traditional designs, drastically cutting localized pressure drops and fluid shear noise.

Application Areas

The high-efficiency replacement Type 0450 solenoid valves from Chengyuan are widely used in robust fluid networks and automated process lines, including:

• Heavy Machinery Pneumatic Workholding & High-Flow Main Line Air Systems: Executing high-frequency, rapid charging and venting for pneumatic actuators.

• Hydraulic HPU Proportional/Sliding Spool Valve Pilot Supplies: Functioning as the electro-hydraulic pilot command stage for main system activation, unloading, or multi-circuit safety interlocks.

• Industrial Spray Coating, Automated Component Washers, & Water Processing: Providing reliable fluid direction switching and process automation cut-off for medium-pressure pipelines.

Expert Maintenance Tips

• Flush and Purge the Connecting Pipe Networks Completely Before Final Installation: Pilot-operated piston valves (especially with larger H 14.0 orifices) utilize tiny pilot feed channels that are typically only $1\sim 1.5\text{ mm}$ in diameter. If pipe scale, weld spatter, or thread sealant shreds enter the line, they will clog these micro-channels, causing the valve to lock up (failing to open when energized or leaking continuously when shut).

• The Pilot System Strictly Requires an In-Line Operating Pressure Differential of at Least 0.05 MPa (0.5 bar): This is a vital operational parameter for pilot-operated fluid valves. If the system fails to build pressure, or returns straight to an open reservoir without backpressure, the valve cannot establish the necessary pressure differential across the piston. In such cases, the valve will not cycle properly even if fully energized, and a direct-acting valve should be used instead.

• Never Energize the 24V DC Coil Assembly While It Is Mechanically Separated from the Valve Body Sub-Assembly: While DC coils resist burning out better than AC equivalents, operating them without the closed magnetic circuit provided by the iron core distorts the electromagnetic flux fields. This increase in localized eddy currents causes abnormal heat buildup, so always verify that supply voltage variance stays within $\pm 10\%$ to prolong coil service life.
