FEATURES

  • Product Portfolio & Market Positioning

    1.1 Product Introduction

    Stainless Steel Float Valves: These precision-engineered valves utilize a float mechanism to automatically maintain preset liquid levels in tanks and vessels. Manufactured in stainless steel materials (SS304, SS316L), they are suitable for aggressive liquids and hygienic applications. The float actuates a pilot valve that shuts off flow when the liquid reaches the high-level set point and opens when the level drops. Seal materials are selected based on application requirements—NBR for water applications, EPDM or Viton for aggressive chemicals and elevated temperatures.

     

    Water Level Control Switches: These magnetically actuated level switches utilize a float containing a permanent magnet that travels along a stem containing hermetically sealed reed switches. As the float rises or lowers with the liquid level, the magnetic field actuates the reed switch, providing open or closed contact signals for pump control, valve actuation, or alarm systems. Available in vertical and horizontal configurations with stainless steel construction.

     

    Oil Tank Level Float Switches: Designed specifically for hydrocarbon and oil-based fluid applications, these switches feature stainless steel housings and floats with chemical compatibility optimized for oils, fuels, and lubricants. They operate reliably in high-temperature environments and provide accurate liquid level control for automotive, industrial, and fuel storage applications.

     

    Oil Level Intelligent Float Sensors: These advanced sensing devices integrate precision float mechanisms with intelligent electronics for real-time oil level monitoring. Engineered for demanding applications in automotive engines, heavy-duty trucks, and industrial equipment, these sensors provide continuous level indication with exceptional reliability. Material selection is critical—PPS (Polyphenylene Sulphide) offers superior chemical resistance up to 120°C, while PVDF provides excellent resistance to strong acids and bases with continuous service up to 105°C.
