Post Indicator Valve

Post Indicator Valve:

Post Indicator Valves (PIV) is used to access the fire water ring, these posts are installed on NRS (Non-Rising Stem Valve), Fire post valves allow this possibility It allows you to open and close the valve on the fire line without accessing the pit, and the opening and closing of the valve is shown by the display on the indicator of post valve.

Types of Post Indicator Valve:

Arka Sanat company produces all kinds of post indicators and according to below codes, post plates for firefighting valve and these valves are made in two models; casting body and welding body:

Cast iron body Post Indicator with manual lever type actuator with model number: RK-PIV-120

Carbon steel welded body Post Indicator with manual lever type actuator with model number: RK-PIV-121

Cast iron body Post Indicator with gearbox type actuator with model number: RK-PIV-220

Carbon steel welded body Post Indicator with gearbox type actuator with model number: RK-PIV-221

Carbon steel welded body Post Plate Valve with manual lever type actuator with model number: RK-PIV-321

Post Indicator Valve Size:

Post Indicator Valve and Post Plate Valve are produce with sizes from 2 inches to 24 inches.

Arka Sanat Company produces its indicators with cast iron and carbon steel telescopically up to 24 inches, which allows to adjust the height and depth of the post indicator.

Components of Post Indicator Valve:

Post indicator valves are generally divided in two parts: the main valve and the post that is mounted on the valve and other components are detailed as follows:

Main Valve Indicator

post body

Stem and main shaft

Valve open and closed display

Shaft interface with bolts and nuts

Telescopic to increase and decrease height

Interior mechanism of gears to transfer the open and closed position of the valve to the display

Special wrench with lock or gearbox

Suitable Valves to install post indicator valve and post plate:

The valves related to these indicator valves are supplied valve manufacturing companies from AVL, and Arka Sanat post are mounted on its, the valves on which it is possible to install posts, including:

Gate Valve (EPDM, Non-Rising Stem)

Gate Valve (Metal to Metal Seat, Rising-Stem)

Butterfly Valve (Flange)

Post Indicator Valve Application:

Post Indicator and Post Plate Valves are used to fire water under-ground ring as a isolation valve, and this allows us to have quick access to cut off and connect the fire water flow, the most common uses of post indicator valves are as follows:

At the entrance, exit and separation of fire water zones

At the entrance of firefighting water to hydrants

In places where the underground fire ring is divided into several parts

In places where the underground fire water ring is closed loop

Before the places where there is a possibility of damage to the underground fire network.

Post Indicator Valve Advantages:

In previous years, gate valves inside the pit were used to isolate fire water flow of underground firefighting networks, so that there were places a concrete or metal pit was previously installed along the firefighting network to install isolation valve placed inside them. but with the design of post indicator valves, it was no longer necessary to implement a pit, and the post valve was installed directly in fire network line and its surroundings are filled with soil or sand, because these valves have the ability to turn-on/turn-off water flow and even show the opening and closing of the valve, so station valves have the following advantages :

DON’T need to install a pit in the network of firefighting underground lines (firefighting ring)

The possibility of disconnecting/connecting the fire water flow from the post indicator.

It is possible to know and display whether the valve is open or closed.

Having a dedicated lock for security and non-technical personnel intervention to open/close the valve

It has telescopic capability and the possibility of increasing/decreasing the height and depth.

Post Indicator Valve Warranty:

Arka Sanat company guarantees its post indicator for 12 months after installation and 18 months after sale, and this will vary depending on the type of material used in it.
