Introduction
The U.S. Solid USS-SV series 3-way solenoid valve is a versatile directional control valve designed for various industrial applications. By selecting different inlet ports, this valve can be configured for either Normally Closed (NC) operation or Changeover operation with a Normally Open default flow path. Designed with high-quality EPDM seals for excellent water and steam resistance, and rated IP65 for outdoor use.
Applications
Features
- 3-Way Design: Switchable between Normally Closed and Changeover operation - versatile for multiple applications.
- IP65 Waterproof: Rated for outdoor use, resistant to rain and splashes.
- EPDM Seal: Excellent resistance to water, steam, and weathering.
- Junction Box Connection: Easy wiring with terminal block, polarity-free for simple installation.
- NPT Thread: Standardized National Pipe Taper (NPT) connection provides a tight, reliable seal. Teflon tape is recommended for proper sealing.
- Valve Body Material: Constructed from corrosion-resistant stainless steel. Suitable for drinking water applications (compliant with standards).
- Normally Closed / Changeover: Normally Closed mode blocks flow when de-energized; Changeover mode redirects flow between two outlets upon energizing, offering flexible circuit control.

Operating Principle
- Normally Closed (NC) — Port 2 as Inlet: In the de-energized (power-off) state, all flow paths are blocked. When energized, fluid flows from Port 2 to Port 1, while Port 3 remains closed.
- Changeover Function (Normally Open Default) — Port 1 as Inlet: In the de-energized state, fluid flows from Port 1 to Port 3 (default open path). When energized, the flow path switches to Port 2, and Port 3 is shut off.
FAQ
Problem 1: What's the difference between JFSV02001 and JFSV02002?
USS-SV02001 features a brass body while USS-SV02002 features a stainless steel body. Stainless steel offers better corrosion resistance for harsh environments.
Problem 2: Can this valve handle steam?
Yes, the EPDM seal is excellent for steam applications up to 248°F (120°C). EPDM is not compatible with petroleum oils, fuels, lubricants, ketones, esters, chlorinated solvents, or strong oxidizers.
Problem 3: Is this valve suitable for outdoor use?
Yes, with IP65 rating, this valve is protected against water spray and can be used outdoors. However, it is recommended to install in a protective housing for permanent outdoor installations to ensure long-term durability.
Problem 4: How do I wire this valve?
This valve uses a Junction Box connection. Simply open the junction box and connect your power wires to the terminal block inside. Polarity does not affect operation.
Problem 5: Can this valve be used continuously?
It is recommended to not energize for more than 6 hours continuously. If continuous operation is required, use a fan to keep the coil cool.
Problem 6: Can this be used for drinking water?
Yes. This solenoid valve is made of food-grade stainless steel, meeting drinking water standards. It is safe for potable water with no lead risk (unlike brass valves).
Precautions
- It is recommended to filter the fluid before use to prevent impurities from blocking the valve, which could lead to incomplete closure.
- Flow Direction: During installation, ensure the arrow on the valve body aligns with the medium's flow direction. If reverse pressure is possible, install a check valve to prevent backflow.
- To ensure optimal performance and extend the solenoid valve's lifespan, install it horizontally with the coil facing vertically upward. Avoid vertical or backward coil orientation.
- The solenoid valve generates heat during operation. Avoid direct contact with your hands.
- Solenoid valves that have been out of service for an extended period should be cleaned to remove any accumulated impurities or condensation before use.
- To ensure a secure seal, always use Teflon tape when connecting NPT threads.
- Do not energize the valve for more than 6 hours continuously to prevent coil burnout.
