No – TIR Pressure regulators are NOT polarity specific.
Check that the pressure adapter is installed between the pump and the pressure regulator. Then check for by-pass flow likely to the agitator being too great.
Assemble into the first solenoid valve for 2500, 2100, and 2502. Assemble into the center boom outlet on the 1999.
Depends on the GPM per boom and expected spray pressure.
The pressure at which you spray plus up to 20 psi normality based on GPM. GPM is quickly arrived at adding the GPM of nozzle on that section of boom to arrive at a total GPM per boom. Allow 10% over the calculation to determine a minimum for the valve need.
The TIR Pressure Regulator is installed with the return line connected to it.
Check the resistance – should be about 6 for the 2.0A solenoids and 11 for the 1.1 solenoids. The other way to test is to use jumper sires and energize from a battery holding the plunger in the tube to determine if the solenoid will draw it in.
The solenoid works or it does not. Partial flow indicates that there is block between the plunger and the top inside of the solenoid, the seal is sticking to the seat.
Have a loose connection on the positive wire on that solenoid.
The motor was installed while energized open. Pull the motor cotter pin and remove the motor. Rotate the ball stem 180′ and realign the motor to the stem shaft and insert the pin.
Blue – Left / Brown – Middle / Black – Right.
Plug a red wire on to each solenoid, then plug in the colored wires according to boom.
No “click” – likely “Stuck” either the seal or the plunger
It is best to place the valves in a position where they will drain with gravity when not in use. When that is not possible, straight RV Antifreeze it recommended to fill the valve bodies.
Solenoids only control the On/Off flow. From TIR’s known instances of cause – check the steel seal disc to verify that the rubber is still bonded to the washer on both sides — the pilot holes must remain open. Check the diaphragm that it returns to semi flat shape when disassembled. If it retains the cup form like when the valve is closed, it needs replaced.
It is a solenoid that has an imbedded computer chip that senses electrical flow and provides full power (amperage) to the valve for 1 second and then reduces the power to about 1/3 the amount rated on the valve while the valve is open. This saves electrical load on the system and the valve will remain open with the temperature maintaining about 10’F over ambient temperature regardless if it is running wet or dry.
The basic set up for the Control System is Pump to Tee to Pressure Adapter to Solenoid Valve to Pressure Regulator to return line. At the tee, the tee goes to an adjustable valve to the agitator line/return line to regulate agitation/system pressure to approximately 15 psi above spraying pressure (use the tractor RPM needed for ground speed when spraying) as a starting point for system set up. Check pressure with valves open and adjust as needed from that point.
A return line is needed to control pressure if the pump will deliver more than the desired spray pressure or the pressure drops below the needed pressure. The return line function is to return varying amounts of by pass fluid to keep the system spray spraying at a constant pressure with varying amounts of volumes being sprayed from the pressure side of the system.
TIR has a Standard RC3 package for connection to competitor ball valves using 3-Pin weather pack connectors
Parts are available. Better? Parts required, time and money is the consideration. Money: If only the internal parts of seals and plungers are needed, cost wise replacement kits are the best value. If the solenoid is needed with the internal parts, the cost is about 65% that of a need valve. Time: Any** of the TIR valves are rebuild able using the parts from off the shelf new valves and leaves the valve body (plumbing) in place. IF you are spraying this can get you back up faster than ordering a needed part.
Suggest trying straight RV Anti Freeze
Spade Terminals use blue connectors from TIR factory and 1/4″ wide thin blades that individual wires connect to. Weather packs are plastic housing that contain both the Pos and Neg wires, clip together like connectors used for making connections for automotive and agricultural vehicles.
The TIR Pressure Regulator is a Butterfly designed valve. It uses interval electrical pulses to actuate clock wise and counter-clock wise, but the TIR control applies these using a toggle switch vs a computer applied pulse based on an algorithm loaded into a computer chip on a circuit board.
Check the main cables for positive wires being exposed to bare metal. Next check for a shorted solenoid.
TIR Pressure Regulator use the Yellow and Green Wires for every system built. The valve is connected to the Yellow and Green wires meant for the Pressure Regulator.
