Description
The HTP 91609 Water Pressure Switch regulates fluid pressure in hydraulic heating systems, activating or deactivating equipment based on the predetermined thresholds. This electromechanical part uses in a diaphragm or bellows mechanism that responds to pressure changes, opening or closing electrical contacts to control pumps, boilers, or safety circuits. Its adjustable setpoint allows technicians to calibrate switching pressure according to specific operational parameters within HVAC system applications. The corrosion-resistant construction withstands continuous water exposure and temperature changes, providing the accurate pressure sensing that maintains system safety and performance standards.
