• For AG chemicals, the standard Santoprene valves are suitable for most applications.                            
• For special applications, different Viton valves & diaphragms may be required.                                   
• Whenever selecting a pump, you should always refer to a chemical compatibility chart (refer to Silvan customer service on 1300 SILVAN) to match the chemical to be used with your pump.                                                                                                                                                   
• Selecta now distribute a Shurflo pump that is fully Viton equipped (Diaphragm & Valves) model 361-.8000-342-136.

•  When agitation is required to direct the flow of liquid back into the tank.                                                                               
• When control of the flow and pressure is required, ie: boom spraying and adjusting pressure for the right application through a spray pistol.                                                                                                              
• Important- suitable to use only on pumps providing more than 5.3L/Min open flow.

The 12v Stripperdomes are fitted with a constant pressure valve (2bar) to stop pump pulsations affecting spray pattern.

The PTO model has a standard non-drip valve. (These parts are not interchangeable)

It reduces the cycling pulsation and increases pump life.  The accumulator tank also assists in controlling and maintaining constant pressure.
