SG307 Series Subplate Mounted Hydraulic Pressure Switches

Product Overview:

The SG307 Series consists of premium subplate-mounted, piston-type hydraulic pressure switches designed for precise control in industrial hydraulic systems. Its primary function is to sense system pressure and convert it into electrical signal outputs, widely used in automatic cycles, safety interlocks, and pressure sequencing circuits. The high-strength piston design provides exceptional repeatability and superior resistance to system pressure pulses. The SG307-F features a standard subplate interface for direct mounting on manifolds or baseplates, significantly reducing leakage risks.

This page features the full range of models: low-pressure SG307-F-55, mid-range SG307-F-150, high-pressure SG307-F-350, and the V2 FKM-sealed versions.

Key Technical Advantages:

• Precision Switching Accuracy: Utilizing a precision-ground piston and micro-switch assembly, it ensures a repeatability tolerance within $\pm 1\%$.

• Versatile Sealing Options: Models with the V2 suffix feature Viton (FKM) seals, ideal for phosphate ester fire-resistant fluids and high-temperature applications.

• Shock & Vibration Resistant: The piston architecture naturally withstands heavy vibrations from reciprocating pumps and high-frequency valve shifting.

• Fast Pressure Adjustment: Equipped with a calibrated adjustment knob or hex socket for intuitive and accurate on-site pressure setting.
