INTRODUCTION
NOTICE
• Drawings and/or pictures in this manual may be exaggerated for
clarity.
• The valve, along with this operating and maintenance instructions
manual, contains trademarks, copyrights, and/or patented
features that are the exclusive property of Victaulic.
The 869E-3D deluge valve operates by an electric three-way solenoid
valve (Figure 1, call out 8), which actuates a hydraulic relay valve
(Figure 1, call out 7) and requires a listed system control panel with a
compatible electric detection system.
The specific trim for the 869E-3D deluge valve includes a hydraulic relay
valve (HRV). The HRV is normally held closed by the actuating pressure
maintained in the hydraulic supply system, and a manual emergency
release (Figure 1, call out 5).
In fire conditions, the fire activates the detection system. The system’s
control panel reacts and opens the solenoid valve to atmosphere (Figure
1, call out 8), releasing pressure from the HRV and causing it to open.
The open HRV releases the pressure from the upper chamber, allowing
the deluge valve (Figure 1, call out 1) to open. Water enters the system
piping and flows from any open sprinklers and/or spray nozzles.
Deluge systems are commonly used where it is desirable to
simultaneously spray water from all open sprinklers and/or nozzles while
the system is operating.
UL LISTING
The 869E-3D deluge valve is UL Listed when installed with specific
components and accessories. Refer to the current UL Directory. Consult
the manufacturer for the most up-to-date component approval in the UL
fire protection equipment directory.

I-869E-3D / 869E-3D On-Off Deluge Valve / Installation, Maintenance, and Testing Manual
OPERATION
The 869E-3D deluge valve is suitable for systems that include electric fire detection, a piping system, and a wide variety of open nozzles.
In the SET position, the line pressure, which is supplied to both the main valve control chamber (Figure 2, call out 1) and hydraulic relay valve (Figure
2, call out 2), through the priming line (Figure 2, call out 3), a check valve (Figure 2, call out 4), an accelerator/priming restriction (Figure 2, call out 5)
and a three-way solenoid (Figure 2, call out 6), is trapped by the check valve, by the closed HRV, and by a closed manual emergency release (Figure
2, call out 7).
The trapped pressure holds the main valve’s diaphragm and plug against the valve seat (Figure 2, call out 8), sealing it drip tight and keeping the
system piping dry. The HRV is held closed by the line pressure through the solenoid.
In the OPERATING position, an electric detection system working through a control panel triggers the solenoid to release to atmosphere, which then
opens the HRV. This causes water to exit through the accelerator/priming restriction faster than it can be supplied. Pressure is then released from the
main valve control chamber by the opened HRV or the manual emergency release, allowing the main valve to open and water to flow into the system
piping and to the alarm device (if mounted).
MANUAL OPERATION
Whenever the handle of the manual emergency release valve (Figure 2, call out 7) is pulled, pressure is released from the top chamber, the deluge
valve will open, and water will flow into system piping and alarm devices.
