Not your cheap valves! These are built to last! An essential part of installing a pool or spa.heat pump, this valve installation kit includes Two 3-Way 40 or 50mm Valves from Jandy or Hayward. 

This allows you to set the correct bypass flow through the heat pump to achieve the 2-5° differential between Inlet & Outlet, as required by most heat pump manufacturers. 

Comes with Genuine Jandy or Hayward valves. 2x Three-way Valve plus 1x Check Valve

Options:

• One-speed Standard Pumps:  Set valves for a 2-3° differential.
• Two-Speed Pumps: Set the 2-3° differential temperature based on low-speed.
• Variable-Speed Pumps: Find what speed your pump is set to when heating, then set the valves for the 2-3° differential.
