Valterra 3 Piece Gate Valve [1 1 2"MPT x 1 1 2"Union] [45 PSI] (6124) leviton 5 kW PS electronic heater 5 kW PS electronic heater is designed for compatible heating applications where a 240 volt L shape heater with a long cord and clamp supported installation is required This type of part is especially useful in power related wiring where removable quick connect terminals are less appropriate than a secured stud mounted connection This model is especially useful in installations where the plumbing layout already favors a removable union on one end rather than a permanently glued connection on both sides The 6124 is a practical option when a compatible 1 1 2 inch system needs a shutoff valve that supports both proper fit and more efficient maintenance planning
