TSJ & TSJ-PRS Series Swing Joints

Maximize the Performance of Your Rotors

TSJ Series Swing Joints connect ¾” (1,9 cm) and 1” (2,5 cm) sprinklers or quick coupler valves to lateral pipes. This allows for easy adjustment of head to grade to prevent heads or pipes from breaking when run over by equipment.

The Rain Bird Turf Swing Joint with Pressure Regulating System (TSJ-PRS) controls and maintains a preset inlet pressure for rotors with 1" inlets. Pressure regulation right at the rotor gives designers more control over the irrigation system performance than other means of regulation.

In very high pressure or fluctuating pressure situations, the TSJ-PRS ensures optimal droplet size and eliminates misting, resulting in improved uniformity and reduced water consumption. The TSJ-PRS can also be used to provide the same pressure to each rotor on a zone in applications where high flow rates result in significant friction losses or where there are elevation changes.

Features

Preassembled units save the contractor time and reduce installation costs
Excellent structural integrity from the swept elbow design reduces the costs associated with fatigue related failures
Double O Ring provides extra protection against leaks and keeps threads clean of debris making hand tightening easy
The TSJ-PRS combines the great flow characteristics of the Rain Bird turf swing joint with an inline pressure regulating outlet elbow for controlling and maintaining constant pressure right at the rotor inlet
Double O Ring provides extra protection against leaks and keeps threads clean of debris making hand tightening easy

1" joint pressure loss: 1.5 psi at 18 gpm; 2.5 psi at 23 gpm (0.1 bar at 1.1 l/s; 0.2 bar at 1.5 l/s)
TSJ-PRS maximum flow: 22 gpm (1.4 l/s)
TSJ-PRS Application Information:
The TSJ-PRS is not recommended for use in systems where the pressure in the lateral lines is equal to or less than the nominal regulation pressure, as the increased pressure drop may adversely affect the performance of such systems
To reduce the effects of water hammer, Rain Bird recommends flow rates in the supply line not exceed 5 ft/sec (1.5 m/s). The TSJ-PRS is not intended to function as a water hammer prevention device
There are no user-serviceable parts inside. The internal spring is under compression. Do not open the PRS unit under any circumstances
