STYLE 8840 HI CYCLE ELECTRIC VALVE
INSTRUCTIONS AND PARTS LIST
GENERAL INFORMATION
The Style 8840 Valve utilizes a flat ball concept providing an open area greater than a typical 4” waterway. This design features a 4” long body and has
easy operation with limited friction loss.
The valve has the Swing-Out™ feature and is designed for easy service with only one seat and an aluminum bronze flat ball which will rarely need to be
changed.
The valve has a rated working pressure of 250 PSI in the flow direction, but will hold 100 PSI in the reverse direction. It is hydrostatically rated at 500
PSI.
This valve is single directional and must be installed with the 250 PSI directional arrow (cast on valve body) pointing away from the pump regardless if it
is for discharge or intake applications.
NOTE: If the valve is used as an intake, it must be installed with the 250 psi directional arrow towards the swivel intake.
The electric actuator is reduced to 25:1 and will travel from full open to full close in approximately 8-10 seconds.
INSTALLATION
1. Plumb into the pump system as usual being sure to heed the flow directional arrow cast on the body.
2. The actuators can be mounted in one of four positions.
3. Keep the piping aligned so undue stresses are not placed on the valve. Victaulic connections in lieu of pipe threads do help.
4. Be sure the white flange seal rings are in place before installing the valve. Close the flat ball before attaching flanges to body.
5. Snug up flange bolts alternately (not adjacently) when securing flanges to valve body. Tighten each to 60-70 foot pounds. (Also alternately)
6. Electric actuators should be installed in a direction where the manual override is accessible.
7. If any welding is to be done on the truck, disconnect electrical connections until welding is finished.
NOTE: If the actuators are removed for repositioning, always use Loctite 222 or Permabond LM113 on the mounting screws.
NOTE: Pressures over 100 psi in the direction opposite to the arrow cast into the body could allow a small volume of water to pass through the valve
on the upstream side. Back pressures up to 250 psi, will not affect the valve seating system or fire pump.
PRESSURE TRANSDUCER
Use a thread seal and tighten only until snug plus an extra 1/8 to 1/4 turn. Over tightening of the metal fitting may cause a slight zero shift.
CAUTION: Reverse excitation will permanently damage the unit. Follow the wiring instructions carefully.
