Post indication valves were developed and patented by innovators Crookham and Lee in 1972 for Clow Corp., a pipeline manufacturing company, and were publicly installed for the first time in 1974.

Understood as PIV, indication post, I publish, IP, post indicator, or wall post, a post sign valve is a valve assembly used for the function of underground piping for water supply to fire defense systems such as sprinklers, sprays, foams, deluges, and so on. These systems usually have a lockable actuator which appears like a red metal guiding wheel or a wrench/handle on top of a post. It likewise has a glass or plastic window, which suggests whether the valve is open or shut. These valve systems can be recognized by the post indicator valve symbol, which http://www.bbc.co.uk/search?q=plumbing shows the acronym PIV inside a circle.

Kinds of Post Indication Valves

PIVs can be broadly divided into 3 types:

Ground Post: This is an indication post which has its base buried in the ground, and normally has a lockable manage or wrench. It is utilized when the valve is located out of the structure.

Wall Post: This is a brief sign post, generally bolted horizontally to the wall of the structure through a flange. This post is run through a handwheel. This is utilized when the water mains go through a wall cavity.

Pedestal Post: This sign post looks much like a ground post. Nevertheless, rather of being buried in the ground, it is bolted through a flange to a horizontal surface area, generally a platform of concrete. It is likewise run through a lockable handle or wrench. It is utilized when the valve lies inside a structure, and the water mains are underground.

All these are readily available in a range of sizes, which range from 3 – 10 inches in width. Nowadays, electronic PIVs are also offered, which communicate with the emergency alarm system whenever the valve is opened or closed.

Post sign valves and fire department connections are typically situated close to each other, so that the water can be supplied to the system even in case of PIV failures. The fire department connections can be found in 2 unique styles.:

Wall Mounts: These setups have 2 nozzles that are mounted on a round plate of brass, horizontally on a wall.

Free Standing: This setup likewise usually includes two nozzles. Nevertheless, they are installed on a vertical pipe instead of a wall.

The fire department connections are not controlled by PIVs, but rather utilize fire department pumpers. Let's now take a look at what a post indication valve does while running the mechanism.

How Do Post Sign Valves Work?

The actuator and the visual sign are on the post, which permits the valve to be opened and closed quickly by moving the actuator, and examining its position through the 'OPEN' or 'SHUT' notification in the sign.

Functioning

A post sign valve functions to manage the water flow to control plumbers in albuquerque fire systems such as hydrants and sprinklers that lie in or near public or private structures, factories, and warehouses, to secure the structures from fires. It is used to cut off supply of water to the systems in case of emergencies or for upkeep factors, and may or may not be needed depending on the fire department requirements for the area.

PIVs are likewise utilized to transfer process water, i.e., water which, throughout manufacturing or processing, comes into direct contact with or arises from the production or use of any raw material, intermediate item, completed product, byproduct, or waste product. While red post sign valves are designated for stopping fires, the yellow, green, and blue ones are utilized for domestic functions and for managing water utilized for commercial purposes.

It is necessary that PIVs are preserved regularly so that problems such as leaks or failures in operation are taken on promptly. This will save a great deal of cash by preventing replacement of parts, and fines for carelessness.
