USF Series Brass 2/2-Way Solenoid Valve
- Pilot Operated, Normally Closed
- Port Size: 1/2"–2" (flanged)
- Fluid Temperature: -5°C to 180°C
- Operating Pressure: 0.07–1.6MPa
- Media: hot oil, hot water, steam
USF series is a solenoid valve specifically designed for high-temperature steam environments. It adopts a plunger with a dual-directional guide system that prevents deformation or sticking under extreme heat while maintaining precise alignment and reliable sealing. The metal-encased coil provides excellent heat dissipation, and the flanged connections comply with industrial piping standards for secure installation. By addressing common failure issues in high-temperature solenoid valves, this valve delivers enhanced durability, extended service life, and stable operation under continuous high-temperature conditions.
- The plunger structure with upper and lower PTFE sealing rings resists high-temperature deformation and ensures long-term reliable sealing
- Dual-direction guide system enables smooth piston motion and prevents sticking from heat fluctuations
- Open-top design allows easy inspection and maintenance of internal components
- High-voltage magnetic field design with self-balancing clearance structure improve operational stability under high-temperature
This solenoid valve is mainly used in steam distribution systems in high-temperature industrial environments that require reliable shut-off and control of saturated or high-temperature steam, such as:
- Pharmaceutical sterilization equipment
- Food-processing machinery
- Industrial dryer equipment
