HDPE Spacers
For road-crossing where the fluid carrying pipe cannot be buried directly. The movement of heavy vehicles will transfer impact loads and can damage pipeline with leaking water or gas etc. In all such cases, the carrier pipe is inserted into a sleeve pipe. Spacers allow the carrier pipe to be easily pulled into the existing sleeve pipe and the traffic loads do not reach the main service pipelines. Small size carrier pipes DN50 to very large DN3000

D Type
D 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.
D Type Hydrants are used in low pressure applications where the outlets have a flow limiter in order to provide constant flow rate to the farmer. Number of outlets on the body can be increased up to 2 outlets, enabling supply to more than one farmer from a single hydrant.
Expansion Joints
For water, waste water, chilled water & many other services, to permit pipelines “flex” a bit. Metallic pipes expand and contract when the ambient (or service) temperatures vary and non-metallic pipes (which may be buried) will move with ground settlement etc. Where probable movement can be envisaged the values are designed by a compensator which can flex, thus avoiding undue pipeline damage. Interesting applications are reservoir inlet/outlet connections, pump connections, differing flange standards either end, axial or angular offset of new to old pipelines. Sizes from DN50 to DN5000 and pressures of PN6 to PN25 on rubber, but the larger sizes would be lower pressure capability.. Higher pressures and temperatures in 316SS.
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.
Pump Control Active Check valves
Pump Control Valves protect pumps, pipelines, and other system components by isolating the pipeline from the sudden velocity changes associated with pump starting and stopping.
The “Active Check Valve” logic of operation, is the method of pumping system control that prevents surges rather than eliminating them.
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.
Level Control
Float controlled valves combine the advantages of excellent hydraulic control valves with the simplicity of mechanical floats.
The ability to separate the main valve from the float enables eliminating most of the installation and maintenance problems associated with mechanical float valves.
Level Control Valve with Modulating Horizontal Float is used to control reservoir filling to maintain constant water level regardless of fluctuating demand.
