This fixed price listing is for a Adjustable Spear Valve used for Micro Hydro power projects.  Made from high density plastic for Turgo wheels and Pelton wheels.

     The same Spear Valve is used in a Motenergy hydro power system and kit.  For the Motenergy Hydro Power Generators, you can have up to 4 nozzles on one blue base box.

     Threads are 1 1/2 inch G threads.  You can connect with a Rubber Adapter and hose clamp, or buy a 1 1/2 inch G Female to 1 1/2 inch Male NPT adapter.

     Here are a few good equations you my need to calculate the power on your site:

Flow in GPM x Height in Feet x 0.18 x 0.5 = Output Power

(Flow in Liters per second x 15) x (Height in Meters x 3.3) x 1.8 x 0.5 = Output Power in watts

Note:  For international buyers, you may have to pay some Duty or VAT when the goods arrive in your country.
