Series 38KRI liquid solenoid valve pilot

The Spartan Scientific Series 38KRI liquid pilot valve is a miniature solenoid-operated pilot valve, specifically designed for the precise control of liquids and inert gases. This 3-way, 2-position valve is optimized for mounting on flat manifolds and offers a compact, reliable design with a fully molded coil assembly. The valve is unique due to its internal piloted exhaust, making the normally open (NO) version more cost-effective by having all ports contained within the valve body. The valve is equipped with a turn-lock manual override and a fast response time of 8–15 ms, making it ideal for pneumatic control circuits, medical equipment, and industrial automation. It supports pressures up to 150 psi and a temperature range of +10°C to +50°C, with IP65/NEMA 4 protection against dust and water.

Advantages

  • Dust-tight and water-resistant (IP65/NEMA 4) for demanding industrial environments.
  • Wide voltage range for flexible application in various systems.
  • Simple mounting with two standard screws.
  • Suitable for liquids and inert gases in industrial and medical applications.
  • Long lifespan due to high-quality materials and precision engineering.
  • Flexible connection options (spade terminals or flying leads) for easy installation.
