21. If there are any problems with the valve upon reassembly, or if difficulties arise in assembling

with the proper spring torque, please contact Champion immediately and do not install a faulty

valve into any application.

NOTE: EYE PROTECTION IS RECOMMENDED WHEN DISASSEMBLING AND ASSEMBLING CHAMPION

CHECK VALVES.

Installation of Replacement Spring

1. Carefully detach the spring from the spring adaptor and eye bolt. Spring may have tension so be

careful in this step. Removing a loaded spring can cause serious injuries if done without caution.

2. Install new or replacement spring by carefully looping one of the looped ends through the eye

bolt at the bottom of the bracket and then stretching the spring to loop the top loop through

the arm of the spring adapter. If this is too difficult, try loosening the eye bolt and repositioning

to make the spring length shorter. Be careful with the spring when it is loaded as releasing a

loaded spring can cause serious injuries.

3. Once the spring is installed, sit the valve upright and test the cracking pressure of the valve by

pushing against the disc in the downstream direct.

4. If the valve opens too easily, the spring needs to be stiffened. This can be done by detaching the

spring, and detaching the eye bolt and moving it downwards away from the spring adapter. Re-

tighten the eye bolt into place, and then reinstall the spring. Again be careful when installing the

spring as releasing a loaded spring can cause serious injuries.

5. If the valve is too hard to open, and it is clear that it is because the spring is too stiff, the spring

needs to be loosened. This can be done by detaching the spring, and detaching the eye bolt and

moving it upwards towards the spring adaptor. Re-tighten the eye bolt into place, and then

reinstall the spring. Again be careful when installing the spring as releasing a loaded spring can

cause serious injuries.

6. If there are any problems with the valve upon reassembly, or if difficulties arise in assembling

with the proper spring torque, please contact Champion immediately and do not install a faulty

valve into any application
