Abstract: A venting probe insertion chamber that is attached to a uniquely designed port which combines the attributes of a probe insertion chamber along with the ability to vent to atmosphere gasses that are present in piping system. This invention combines the functions of two existing products in an economically viable product. This inventive design performs all task required without the need for O-rings or sealing elements present on prior art products. Creating a simpler to manufacture and maintain device that allow for a user to obtain accurate readings of temperature and pressure while using a minimal amount of tooling. The user is able to remove the protective cap while using only a single tool to prevent dislodgement of the product from the associated port. Current state of the art can potentially place a user in harm as accidental dislodgement of their product can occur having only a single operator.

Abstract: An improved replaceable valve shaft sealing system is disclosed that enables the operator to greatly reduce the maintenance needs of valves where rotational movement of a shaft, that is connected to the actual metering apparatus of the valve, actuates the opening or closing of the valve thereby regulating fluid flow. Such valves are subjected to differentiations in pressure, including the suction that occurs during pressure drops, temperature, which directly effects the valve body material and tolerances through thermal expansion, degradation of the sealing members due to presence of chemicals and absence of lubrication and wear due to the constant adjustment of the valve due to environmental variables, Current designs use O-rings to prevent the seepage of fluid into the valve body and though the rotating shaft, but current designs do little to prevent contamination of the lubrication into the fluid flow nor eliminate any of the axial loads that can cause O-rings to fail.

Abstract: A high differential pressure, low torque precision temperature control valve is disclosed herein. This valve is trunnionated with stem components that are separable from the plug for ease of maintenance and manufacturability and thus reducing the need to remove the entire plug and sealing assemblies in the field. Field repair of stem sealing devices can be accomplished inline. The stem design can be smaller in diameter with smaller bearing surfaces than would be anticipated creating a lower requirement of torque to rotationally transposition the plug within the fluid chamber while under high pressure. This valve's lower trunnionated stem is stationery reducing the problems associated with o-ring failure and leakage problems with objects that rotate. Due to the design of the orifices in the plug, this valve is capable of repeatability at lower opening ranges than prior art valves and reduces jetting, caviation and erosion often associated with lower opening ranges.
