Butterfield, MN | What type of valve is programmed in? If it's a PWM valve, you'll be in good shape, since you can program in a Minimum PWM value to make sure the control valve never closes enough to let the pressure drop down. If it's a servo valve, standard or fast type, you can program in a low limit, which will not let the valve close down below a certain point typically for the number of gallons per minute. This will help prevent the valve from closing all the way so you lose all of the system pressure. | |
