Single Chamber & Four Function Non-Slam
Non-Slam Air Release and Vacuum Valves are designed to perform the three functions of Double Chamber Air Release and Vacuum Valves, and an additional damping function to protect the system from a possible water hammer:
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, while pipelines are being drained.
3. Discharge of pressurized air pockets during the operation.
4. Prevention of slamming during the operation and the start-up of the system by forming an air cushion in the system.
Solenoid Control
Solenoid Control Valves are simple electrically activated on/off valves that can be of critical importance in controlling flow in every water system.
The electrical signal used to activate the solenoid can be sent from timers, relays, clocks, pressure, level or flow transmitters, etc.
Surge Anticipating
Abrupt pump stopping is followed by a pressure drop as the water column continues traveling along the line.
The returning column hits the closed pump check valve, creating a high pressure surge wave, which travels at up to 4 Mach.
Eliminating such surge requires anticipation and pre-action.
Surge Anticipating Valves react to the pressure drop, accepting the returning column while already open, thus eliminating the surge.
Swing Type
Swing Type Check Valves are designed to have drip tight sealing in case of back flow.
The disc is opened in normal flow direction, providing laminar flow.
When there is a pressure change in the system and flow is coming back, the disc acts and closes the valve.
Accessories that enable slow or fast closing of the disc are available upon request.
Triple Function Sewage
Air Release & Vacuum Valves for Sewage are designed to perform three functions in a single body for use in wastewater/ sewage systems:
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, while pipelines are being drained.
3. Discharge of pressurized air pockets during the operation.
Due to its special sealing mechanism, the air valve does not get plugged and can operate in liquids with particles.
Type TR
Centering clamps for medium and medium pipes
large diameter. They are also designed to be
used for long load-bearing pipes, where it is very
important to reduce friction when
the introduction of a new pipe in
new or old ducts/ducts; Casters help
The new hose to move more easily during
installation. Assembling unit assemblies
spacing is facilitated by a snap-in system,
Ultrasonic
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.
Underground Type
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.
