Temperature: 32 to 180°F Duty: Continuous duty to 150% of rated voltage
Available Voltage: 6, 12, 24 VDC

Description:
R-781 is a combination venturi vacuum generator and an independent pilot actuated electronically controlled, spring return, fully
ported 3-way valve. Applying pressure at port 5 creates a vacuum at port 7. The 3-way valve can be used to turn the vacuum
generator on or off or it can be used to switch the vacuum on or off. To shift the 3-way valve 40 psig is required at port 4 along
with the appropriate DC voltage being applied to the solenoid.

Description:
The R-782 is a combination venturi vacuum generator and an independent pilot actuated electronically controlled, air pilot return,
fully ported 3-way valve. Applying pressure at port 5 creates a vacuum at port 7. The 3-way valve can be used to turn the vacuum
generator on or off or it can be used to switch the vacuum on or off. To shift the 3-way valve 20 psig is required at port 4 along
with the appropriate DC voltage being applied to the solenoid. To return the valve a pilot pressure of 20 psig is required at port 6.
