1/2" IPS Posi-Temp Pressure Balancing Rough-In Valve (With Stops)

Moen 62390 Posi-Temp 1/2" IPS Pressure-Balancing Valve with M-PACT System

The Moen 62390 is a four-port, pressure-balancing valve engineered for 1/2" IPS connections. It incorporates Moen's Posi-Temp® technology to deliver consistent water temperature performance and prevent fluctuations caused by pressure changes in the hot or cold supply lines. Designed for use with the M-PACT® common valve system, this valve enables fast and flexible trim upgrades without disturbing plumbing behind the wall.

Product Highlights

• Pressure-Balancing Function: Maintains consistent outlet temperature even when supply conditions vary.
• M-PACT® Valve Platform: Allows trim swaps without valve replacement, streamlining fixture updates over time.
• 1/2" IPS Inlets/Outlets: Standard connection size compatible with copper or iron pipe installations.
• 1222 Cartridge Included: Pre-installed Posi-Temp cartridge offers durable, reliable water flow control.
• Four-Port Configuration: Supports conventional tub/shower installations with top outlet for shower riser and bottom outlet for tub spout.

Installation Considerations

Designed for new construction or retrofit work, the Moen 62390 should be installed according to local plumbing codes. Mounting depth, valve orientation, and rough-in alignment are critical for proper trim fit. Threaded IPS connections require appropriate sealing methods (e.g., PTFE tape or pipe dope). Professional installation is recommended for accuracy and code compliance.

Field Notes for Contractors

• Trim Change Flexibility: The M-PACT system allows quick upgrades without replacing the rough-in body, reducing future service time.
• Anti-Scald Performance: Integrated pressure-balancing mechanism provides consistent temperature for end-user safety in residential and commercial environments.
• Rugged Design: Brass valve body construction ensures long service life and resistance to corrosion.

Applications

• Residential and light commercial shower/tub installations
• Projects requiring code-compliant temperature control valves
• Installations where long-term trim flexibility is desired
