Product Description

20PS-2.65 Pressure Switch (Wired, 7/16-20UNF Female)

A reliable medium-high pressure control solution, the 20PS-2.65 is engineered for precise pressure switching with a 7/16-20UNF female thread and wired connection. It’s tailored to meet the protection needs of HVAC systems, refrigeration equipment, and industrial machinery operating under medium-high pressure, combining robust performance and user-friendly design.

Core Advantages

Precise pressure control: Triggers OFF at 2.65MPa to prevent overpressure damage and auto-resets ON at 2.0MPa, ensuring timely system protection and recovery.
Easy integration: 7/16-20UNF female thread (standard for industrial pipelines) enables secure connection. Wired design ensures stable electrical transmission, while factory-pre-set parameters eliminate on-site adjustment.
Durable & safe: Sealed structural design enhances leak-proof performance and reliability, with wide temperature tolerance to adapt to harsh working environments.

Working Principle

Equipped with an internal reversible stainless steel diaphragm. When system pressure reaches 2.65MPa, the diaphragm flips to disconnect the switch (OFF), avoiding overpressure-related failures. As pressure drops to 2.0MPa, 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 Medium-High Pressure Systems

Ideal for commercial and industrial air conditioning units, large-scale refrigeration systems, and cooling equipment with medium-high pressure refrigerant circuits. The 7/16-20UNF female thread fits standard industrial pipelines, protecting compressors and pipelines from damage caused by pressure spikes, and maintaining stable cooling efficiency in commercial buildings and industrial facilities.

Industrial Medium-High Pressure Equipment

Suitable for hydraulic systems, high-pressure pneumatic tools, pressure vessels, and industrial process pipelines. Widely used in manufacturing, construction machinery, and automotive production lines. The wired connection ensures stable signal transmission, while the wide temperature adaptability (-30°C~+80°C) allows operation in various industrial environments, providing consistent medium-high pressure protection for critical machinery.
