Product Description
ST307 Series Piston-Type Hydraulic Pressure Switches (FKM Sealed)
Product Overview:
The ST307 Series pressure switches are high-precision piston-actuated components designed for direct inline or threaded mounting in industrial hydraulic circuits. These switches are engineered to monitor system pressure and deliver accurate electrical feedback for sequence control and safety interlocks. Specifically equipped with V2 Fluororubber (FKM/Viton) seals, the ST307 series excels in applications involving phosphate ester fire-resistant fluids, high temperatures, and corrosive media. Whether in heavy-duty presses or precision power units, the ST307 series ensures exceptional repeatability and extended service life.
Featured on this page are the high-pressure ST307-V2-350-B, the ST307-SCH-V2-350-B equipped with high-reliability switching components, and the low-pressure specialized ST307-V2-AS-H2-55-B.
Key Technical Advantages:
Enhanced V2 FKM Sealing: Standard Viton seals offer superior thermal resistance and chemical compatibility, effectively preventing leaks in specialized fluid environments.
Shock-Resistant Piston Design: The piston architecture provides far greater stability than diaphragm types when handling high pressures (up to 350 Bar) and frequent pressure surges.
SCH-Grade Reliability: Models with the SCH suffix feature reinforced micro-switch components, significantly enhancing electrical life during high-frequency switching cycles.
Wide Pressure Coverage: Ranges from 55 Bar for low-pressure logic to 350 Bar for heavy-duty system monitoring are available.
