Riobel PATM23PN 2-Way Thermostatic/Pressure Balance Coaxial Complete Valve, Polished Nickel — Bathroom Sink Faucets & Parts

The Riobel PATM23PN is a 2-way Type T/P valve, combining thermostatic temperature control with pressure-balance protection in a single coaxial cartridge, sold as a complete valve. A 2-way configuration runs two outlets - commonly a shower head and a hand shower, or a shower head and tub spout - from one control.

The thermostatic function holds water temperature steady even when pressure changes elsewhere in the house, while pressure balance protects against sudden temperature spikes. Finished in polished nickel, it pairs with matching Riobel trim for a complete, coordinated shower system.
