Product Description

20PS-0.15 Pressure Switch (Black Housing, Welded Tube)

A compact and reliable low-pressure control device, the 20PS-0.15 comes with a black housing, Φ6(6.35)×1mm welded tube, and blade connection. Engineered for precise low-pressure switching, it’s tailored to meet the protection needs of HVAC systems, refrigeration equipment, and small industrial machinery, combining practical design and stable performance.

Core Advantages

Precise low-pressure protection: Triggers OFF at 0.15MPa to prevent overpressure and auto-resets ON at 0.05MPa, ensuring timely system protection and recovery for low-pressure circuits.
Convenient installation: Φ6(6.35)×1mm welded tube enables secure pipeline integration, while blade connection ensures quick electrical assembly. Factory-pre-set parameters eliminate on-site adjustment.
Durable & distinctive: Black housing offers good corrosion resistance, paired with a sealed structure for leak-proof performance. Wide temperature tolerance adapts to diverse working environments.

Working Principle

Built with an internal reversible stainless steel diaphragm. When system pressure reaches 0.15MPa, the diaphragm flips to disconnect the switch (OFF), avoiding low-pressure system damage. As pressure drops to 0.05MPa, the diaphragm automatically resets, re-engaging the switch (ON) to restore operation—achieving seamless auto-control without manual intervention.

Application

Key Application Scenarios

HVAC & Refrigeration Systems

Perfect for small air conditioning units, household refrigerators, commercial display freezers, and mini cold storage. The Φ6(6.35)×1mm welded tube fits compact low-pressure pipelines, protecting compressors from damage caused by pressure fluctuations. Blade connection ensures quick wiring, maintaining stable cooling efficiency for daily and commercial use.

Small Industrial & Precision Equipment

Suitable for low-pressure pneumatic tools, small hydraulic systems, lubrication circuits, and laboratory precision instruments. Widely used in light manufacturing, electronic assembly, and automotive maintenance tools. Its compact size, black corrosion-resistant housing, and reliable switching make it ideal for scenarios requiring precise low-pressure control in limited installation spaces.
