A three-way valve having a valve body with an internal output chamber. A supply means is in fluid communication with the output chamber for providing a source of fluid to pressurize the output chamber and thereby obtain a desired device output signal. An exhaust means in fluid communication with the output chamber provides a passage for the fluid to vent from the output chamber out to atmosphere. An output means, also in fluid communication with the output chamber, is included for directing the device output signal from the output chamber to a pneumatic device. A single bending element selectively actuates the supply means or the exhaust means to obtain a predetermined pressure value to be maintained by the valve. The bending element is positioned adjacent and between the supply and exhaust means.
