Pressure Control Valves: Releasing Build-up

Any industrial, commercial, refining, circulation, or other production operation involving a system of machinery is also likely to have a system of pipes to move process media throughout the necessary network. These systems often exist within the context of a factory, or another type of location where the systems running circulation for a building or complex are housed. All of these locations are prime spots where pressure can build up during the course of production operations. Pressure control valves are implemented into systems to help control this build-up, and they are able to open and provide necessary release when build-up occurs. Pressure control valves are highly necessary, because the issues that could result from a build-up of too much pressure within a system range from mildly annoying to dangerously severe. In a small mishap related to a large amount of pressure, production may be halted for a certain amount of time and a piece of equipment may need to be repaired. A larger mishap due to pressure build-up, however, could create widespread damage, and possibly injure people close to the source. Pressure control valves can work to release pressure throughout the course of production, and prevent these unwanted situations from occurring at all.

Pressure control valves are designed to open, at which point they allow gas and pressure to escape from an area. Some pressure control valves are designed to be opened manually. This provides a human supervisor with the power to open a valve to release pressure whenever they are able to determine it is necessary to do so. Other types of pressure control valves are designed to respond to a sensor, which determines when the pressure build-up has taken place. The sensor then instructs the valve to open, which releases the extra gas and pressure that has been building within the system. The sensors can be set to a certain point, because every factory condition will have a different ideal point for when it is necessary for the pressure to exit.

The most basic pressure control valves are comprised of a spool and a channel. Gas or pressure is able to use the channel as an exit to escape from the system. In more intricate designs for pressure control valves, a spring is utilized in controlling a bolt, which is able to open or close to allow the excess pressure and gas access to the opening for the escape channel. The spring is designed to respond to the pressure build-up in the context of the factory setting. As pressure builds, the spring condenses, and at a certain point the spring will have condensed enough that the bolt to the channel moves to open the valve. Springs can be designed to respond to different amounts of pressure within a system, which allows companies to order a valve that respond to their needs and open at the pressure level that is most appropriate for their particular operation. Each component of pressure control valves are specially made and intended to respond to pressure conditions within a certain location.
