- Pilot valve housing
- Pilot valve spring
- Pressure nut
- Ball spring
- Diaphragm
- Pressure disc
- Control piston
- Guide ring
- O-rings and seals
The pilot valve sub-assembly is installed in the pilot valve body and connected to the inlet and outlet piping. When the pressure in the inlet piping reaches the set point of the relief valve, the pilot valve opens and allows fluid to flow from the inlet to the outlet piping. This relieves excess pressure in the system and protects the equipment from damage.
The Waterous Pilot Valve Sub-Assembly is a critical component of the Waterous pilot-operated relief valve. It is important to inspect and replace the sub-assembly regularly to ensure that the valve is operating properly.
