Product Description

20PS-3.0 High Pressure Copper Tube

A specialized high-pressure control solution, the 20PS-3.0 is engineered for precise pressure switching in high-demand systems. Featuring a Φ6(6.35)×1mm copper tube design and reliable auto-switching performance, it delivers stable protection for equipment operating under high pressure, combining durability and user-friendliness.

Core Advantages

High-pressure precision: Triggers OFF at 3.0MPa to prevent system overpressure and auto-resets ON at 2.4MPa, ensuring timely protection and recovery.
Robust construction: Φ6(6.35)×1mm high-pressure copper tube ensures pressure resistance and leak-proof performance, adapting to harsh working conditions.
Easy integration: Factory-pre-set pressure parameters enable direct use without on-site adjustment. Supports flexible installation via copper tube welding or compatible connections.

Working Principle

Built with an internal reversible stainless steel diaphragm. When system pressure reaches 3.0MPa, the diaphragm flips to disconnect the switch (OFF), preventing overpressure damage. As pressure drops to 2.4MPa, the diaphragm automatically resets, re-engaging the switch (ON) to restore system operation—achieving seamless auto-protection without manual intervention.

Application

Key Application Scenarios

HVAC & Refrigeration High-Pressure Systems

Ideal for commercial and industrial air conditioning units, large-scale refrigeration systems, and cooling equipment with high-pressure refrigerant circuits. The Φ6(6.35)×1mm copper tube ensures compatibility with high-pressure pipelines, protecting compressors and pipelines from damage caused by pressure spikes, and maintaining stable cooling efficiency.

Industrial High-Pressure Equipment

Suitable for hydraulic systems, high-pressure pneumatic tools, pressure vessels, and industrial process pipelines. Adapts to ambient temperatures of -30°C~+80°C and medium temperatures of -50°C~+120°C, providing reliable pressure protection for manufacturing machinery, construction equipment, and precision industrial systems operating under high pressure.
