<p>A sensing module for a fluid valve utilizes a sensor body (40) having a sensing chamber (41). An extension member (42) is fixedly coupled to a main valve element (27), is slidable within the sensing chamber (41) along a first axis, and has an inclined cam surface (52). A plunger (54) has a cam follower (57) for engaging the cam surface (52) and is slidable along a second axis between a first position when the valve element (27) is in its deactuated position and a second position when the valve element (27) is in its actuated position. The plunger (54) is exposed to the sensing chamber (41). A sensing switch (55) is coupled to the plunger (54) for generating a switch signal indicative of the first and second positions. The valve body (20) and the sensor body (40) cooperate to form a fluid passage between the outlet port (25) and the sensing chamber (41), and the plunger (54) moves to the second position when the valve element (27) is in the deactuated position if a fluid pressure greater than a predetermined pressure is present at the outlet port (25).</p> |
