Underground Air Valves that can be buried under soil are designed to perform three functions:
1. Venting of large volumes of air on the start-up of the system, while pipelines are filled.
2. Intake of large volumes of air on shut-off of the system, which pipelines are being drained.
3. Discharge of pressurized air pockets during the operation.
Due to its Stainless Steel Sleeve, the valve can be buried under soil. As a result, no need for an expensive valve chamber is needed.
Moreover, it does not require any external isolation valve, due to its integral automatic closing mechanism. The valve can be serviced from a Surface Box and taken out for cleaning or maintenance.
B Type Irrigation Hydrants have a special closing mechanism enabling gradual flow increase/decrease when the handwheel is turned, preventing slam closure.
Hydrants are available with an optional anti-frost sleeve for deep water networks, and an automatic drainage valve to bleed the body when the hydrant is closed, to prevent frost damages.
Nozzles that are used in hydrant connection have integral pressure regulator and flow limiter in order to provide constant pressure and flow rate to the farmer. Number of nozzles on the body can be increased up to 2 outlets, enabling supply to more than one farmer from a single hydrant.
Balancing Valves are used in HVAC applications for flow regulation.
Cartridge type Dynamic Balancing Valves provide constant flow rate at a predefined pressure range, thereby providing equal heating or cooling opportunity for various users.
Underground Fire Hydrants are made of ductile iron body, valve mechanism, and a spindle that controls the sealing.
When head of the hydrant is turned counter clockwise, the spindle moves down, sealing the valve at the flow direction. In the reverse action, fire hydrant shuts-off drip tight.
Underground Fire Hydrants are used with Surface Box and are buried in soil. As a result, hydrants are protected from accidents.
Ultrasonic Watermeters read water flow by the help of two ultrasonic probes positioned in the same axis.
In case of a velocity change, variance in ultrasonic waves is detected by the probe and by the help of the processor; these variances are converted into flow rate data.
Flowrate and Consumption Values can be read from the IP68 protected LED Screen.
Furthermore, it provides an alarm in low battery conditions. Internal Lithium Battery can provide power up to 10 years autonomously.
As for communications, the meter has an M-Bus and Optic interface as standard and Pulse or RF interface can be provided optionally.
