Liebert 127935P9S Valve
The Liebert 127935P9S Valve is a critical OEM replacement solenoid designed for high-performance fluid and gas regulation within Liebert environmental control systems. This 2-way normally closed solenoid valve features a 5/8" ODF (OD Female) x 5/8" ODF (OD Male) connection, specifically engineered to provide a secure, leak-proof fit in refrigeration and air conditioning circuits. By utilizing an electromagnetic field to actuate internal flow, the 127935P9S ensures precise metering and rapid shut-off, making it essential for maintaining the operational integrity of precision cooling units in data centers or labs.
Built for the rigors of commercial HVACR applications, this solenoid valve integrates seamlessly with existing system controllers. The "Male x Female" configuration simplifies field installation by allowing direct coupling without additional adapters in many configurations. As a 2-way valve, it serves as a reliable gatekeeper for refrigerant flow, preventing migration during the off-cycle and ensuring system efficiency during active cooling demands.
Key Benefits
- Precision Flow Control: Engineered for refrigerant flow regulation, ensuring accurate thermal management in mission-critical environments.
- Robust OEM Construction: Designed to withstand high-cycle operations common in Liebert precision cooling systems.
- Versatile 5/8" ODF Connections: Features a mixed ODF Male x Female interface for streamlined piping and reduced potential for leak points.
- Normally Closed Logic: Provides safety-first operation by remaining closed during power loss, preventing uncontrolled refrigerant migration.
Common Questions
What is the primary application for the 127935P9S?
This valve is typically installed in Liebert precision cooling units to control the liquid or suction line flow, preventing slugging or liquid migration when the compressor is idle.
Does this valve include the solenoid coil?
The 127935P9S is often sold as the valve body assembly; technicians should verify if the existing coil is compatible or if a new 24V or 120V coil is required based on the system's control voltage.
Can this replace the obsolete 127935P9?
Yes, the 127935P9S is the direct factory replacement for the older 127935P9 model, adhering to the same technical specifications and performance standards.
