Abstract: A switch assembly for a valve actuator can include a bracket, a rotatable switch rotatably coupled to the bracket at an adjustable angle, a fixed switch fixedly mounted to the bracket, an arm rotatably coupled to the bracket, and an adjustable switch trigger coupled to the arm. The rotatable switch can be tripped by the valve actuator and a trip point of the rotatable switch can be calibrated by setting the adjustable angle. The fixed switch can be tripped by the switch trigger on the arm and a trip point of the fixed switch can be set by adjusting the switch trigger relative to the arm. The assembly can include a calibration fixture for calibrating the switch assembly to the valve actuator independently of the valve actuator.

Abstract: A pinch valve can include a finger guard or tubing retainer for blocking at least a portion of a tube slot. A headpiece for a pinch valve can include a tube slot for receiving tubing and can be adapted to couple with a guard. A guard can include a base and an extension and can be removably coupled to a headpiece. The extension can be adapted to block at least a portion of a tube slot.

Abstract: A control module for a pinch valve can include a housing, a controller, a display, one or more indicators and one or more sensors, such as flow sensors, proximity sensors or tube sensors. A control module can support monitoring or operation of one or more pinch valves within a fluid control system. A pinch valve can include one or more control modules and a pinch valve system can include a plurality of pinch valves and a plurality of control modules. A method of controlling a pinch valve can include controlling fluid flow operations based on input from one or more sensors.

Abstract: A valve assembly having a valve body; at least one port to receive tubing; and a collar group to secure the tubing to the port, wherein the collar group is selected from a first collar group configured to secure the tubing by a flattening a washer, thereby driving teeth of the washer into the tubing, and a second collar group having a smooth interior surface to which the tubing is bonded, wherein either the first or the second collar groups may be interchangeably threaded onto the port.
