A mechanical shutdown valve for preventing an over pressure condition is described. A valve body has an inlet, an outlet, and a channel extending from the inlet to the outlet. A valve seat and a diaphragm are positioned in the valve body. The diaphragm controls a fluid flow through the valve body. A mesh is coupled to the diaphragm such that the mesh and the diaphragm separate an upstream portion of the channel from a downstream portion of the channel. The mesh extends from the diaphragm to an inner surface of the valve body and limits fluid flow between the diaphragm and the valve body. A spring biases the diaphragm towards the open position. A characteristic of the spring determines a differential pressure threshold between the upstream portion of the channel and a downstream portion of the channel at which the diaphragm engages the valve seat.

The claimed method and system develops a useful lifetime profile for a component of a process control device, such as a valve, and uses that lifetime profile to determine a projected remaining lifetime for the device component in operation. The lifetime profile is developed from using real world operational data of similar process control devices, used under substantially the same operating conditions as to be experienced during operation. Profiles may be developed for numerous device components, from which a projected lifetime profile for the entire process control device is developed. Based on the projected remaining lifetime, notification warnings may be sent to remote computers and maintenance scheduling may be automatically achieved.

A method for determining the degree of wear of a valve, the degree of wear of the valve being dependent on the degree of wear of an operating element that is made of an expandable material and performs a mechanical movement each time the temperature changes, the change in temperature resulting in wear, the operating element made of an expandable material being mechanically connected to a piston; the movements of the operating element (3) made of an expandable material are calculated by initially sensing the change in temperature on the operating element (3), whereupon the changes in temperature are recalculated as movements on the basis of the temperature/expansion curve applicable to the operating element (3) made of an expandable material.

An integrated diagnostics system utilizes online and offline diagnostics techniques to evaluate control valves found in process plant environments. The integrated diagnostics system improves on existing diagnostic systems, which typically rely exclusively on online diagnostics or offline diagnostics.

A method for determining the end-of-travel positions of a diaphragm in a diaphragm valve having an actuator: initiating displacement of the diaphragm into a first end-of-travel position; ascertaining the first end-of-travel position of the diaphragm, wherein said first end-of-travel position is ascertained by monitoring an actuating current value, wherein the first end-of-travel position is reached when a predefined current value is reached; saving the first end-of-travel position; moving autonomously, preferably in the opposite direction, towards a second end-of-travel position of the diaphragm; ascertaining the second end-of-travel position of the diaphragm, wherein said second end-of-travel position is ascertained by means of a predefined travel length (a) of the diaphragm from the first end-of-travel position; saving the second end-of-travel position.

The embodiments disclosed herein relate to a bracket for a valve system, having an actuator side of the bracket, defining a first set of one or more holes; a valve side of the bracket, wherein the valve side is opposite the actuator side, and further wherein the valve side defines a second set of one or more holes; a wall connecting the actuator side and the valve side; and a strain gauge mounted to the wall.

The present disclosure relates to the technical field of faucets, in particular to an information pushing method and system for a smart faucet. According to the information pushing method and system for the smart faucet of the present disclosure, a trigger signal and a termination signal are acquired by the faucet; an information pushing duration is obtained through calculation based on the trigger signal and the termination signal; and fee-based information is obtained through calculation based on the information pushing duration. Therefore, the duration during which a user actually receives the information pushed by the faucet is reflected, real statistical data which can be provided for an information provider, and meanwhile, an intelligence life experience is brought to users.

A shut-off member for a fluid valve is proposed. The shut-off member includes a blind hole that is made in the shut-off member, the blind hole leading from a dorsal side into a ventral portion; an electronic data carrier which is arranged in a base region of the blind hole; and a casting compound that is introduced into the blind hole and that fixes the electronic data carrier to the shut-off member.
