TEMPERATURE CONTROL DEVICE AND PROCESS CONTROL APPARATUS INCLUDING A TEMPERATURE CONTROL DEVICE
A process control apparatus includes a housing, a process control device disposed in the housing, and a temperature control device operably coupled to the housing for regulating a temperature of an atmosphere internal to the housing. The temperature control device includes a vortex tube and a flow control valve. The flow control valve is coupled to the vortex tube and includes a temperature sensing feature configured to sense a temperature of an atmosphere internal to the housing and configured to move a control element of the flow control valve based on the sensed temperature between a plurality of positions to selectively direct the flow of fluid from the first and second vortex outlets to the atmosphere internal to the housing.

A gas-over-oil actuator system for use with a valve in a natural gas pipeline. The system includes a gas-over-oil actuator and a wireless position monitor operatively coupled to the gas-over-oil actuator. The wireless position monitor includes an integral opened spool valve and is adapted to be communicatively coupled to a remote workstation via a wireless network and a wireless gateway. At least one switching relay is operatively coupled to the gas-over-oil actuator and the wireless position monitor. Upon receiving a wireless command from the remote workstation, the wireless position monitor drives a pressure signal from the opened center spool valve to the at least one switching relay to manage high pressure supply to the gas-over-oil actuator and move the valve to a desired position.

POSITION SENSOR MOUNTS FOR A DIAGNOSTIC SYSTEM FOR FLUID CONTROL VALVES
Position sensor mounts for mounting one or more position sensors to one or more various fluid control valves and/or actuators for such valves. One such position sensor mount includes a base, a toggle clamp fixedly attached to the base, and an engagement assembly. The base has a mount for coupling to a position sensor and a first clamp jaw. The toggle clamp automatically adjusts to provide a fixed clamping force at difference distances between the first clamp jaw and the second clamp jaw. The engagement assembly is carried by the second jaw and includes at least a first clamp pad having a distal end that directly faces the first clamp jaw and swivels relative to the second clamp jaw.

VISUAL INDICATOR MODULES FOR USE WITH CONTROL PANELS AND RELATED METHODS
Visual indicator apparatus for use with control panels and related methods are disclosed. An example visual indicator disclosed herein includes a base defining a light chamber and a first cover removably coupled to the base to cover the light chamber. A light assembly is positioned in the light chamber of the base. The light assembly has a first connector projecting from the base and the first connector is to pass through an access opening formed in an outer surface of a control panel when the visual indicator is coupled to the control panel. The base is to engage the outer surface of the control panel when the visual indicator is coupled to the control panel. The visual indicator is to enable an ingress protection rating of the control panel to be maintained when at least one of the visual indicator is removed from the control panel or the first cover of the visual indicator is replaced with a second cover different than the first cover.
Disk valves to provide an equal percentage fluid flow characteristic are disclosed. An example apparatus includes a disk body (102), a sealing surface (108) of the disk body to form a seal with a valve body in a closed position, and a wall (120) protruding from the disk body. The wall includes an outer surface (122) adjacent a portion of the sealing surface and a depression (126) defined by the outer surface of the wall. The outer surface and the depression provide a substantially equal percentage fluid flow characteristic when the disk body transitions between the closed position and an open position.
