(2) Input signal pressure and the set delay time
Input signal pressure and supply pressure are fed from separate lines for the VR2110 Time Delay
Valve. It is possible to operate the valve at pressure levels independent of each other.
Supply pressure fluctuation is not related to the time delayed switch ON operation. However,
fluctuation of the input signal pressure does influence the time delay. The time delay will decrease
by increasing the input signal pressure with the setting handle fixed in place. Fig. 3 shows this
relationship.
(3) Reset time
The time delay from when Input is turned OFF until Output is turned OFF is the Reset time. The reset
time of the Time Delay Valve varies depending on the signal generating valve type, pressure and
piping length
Note 1)
as shown in Fig. 4.
Note 1) Piping length is the distance for piping from the OUT port of the signal generating valve to the signal
port of the Time Delay Valve.

e.g. “A” in the graph shows the
position when the time delay is
set to 60 seconds for a input
signal pressure of 0.25 MPa. The
time delay will be changed to
position “B” (approximately 40
seconds) when the input signal
pressure is increased to 0.8 MPa.
