ABSTRACT:
An apparatus comprising a valve body having first, second and vent ports and a generally tubular valve element having a peripheral wall with first, second and vent openings in the peripheral wall leading to the interior of the tubular valve element. The valve element is mounted in the valve body for rotational movement between first and second rotational positions and for axial movement between first and second axial positions. A pressure sensor is exposed to the fluid pressure within the valve body. In the first rotational position of the valve element, drip flow is provided between the first and second ports, and in the second rotational position, the vent port is open to provide communication between the pressure sensor and the atmosphere. To provide flush flow between the first and second ports, the valve element is moved to the second axial position.
