Plug Valve
Critically acclaimed for raw sewage lines, for shut off service. Eccentricity of the plug (and its turning away from the flow path) is a great feature in allowing (sewerage) solids to pass freely. Sizes and Pressures. Sizes 3” (DN80) to 48” (DN1200) and Pressures of PN10, PN16. Smaller sizes up to DN300 can also be rated PN25

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.
Crepine Type
Crepine Type Strainers are installed in the entrance of pump suction pipes or in a transition from open channel to closed piping.
The main function is to protect the system from foreign matter like leaves, sticks or stones from the pipelines.
Foreign particles that can harm crucial appliances in the system are stuck in the filter of the strainer, thereby preventing entry to the pipeline.
Aboveground Type
Aboveground Fire Hydrants are made of ductile iron body, valve mechanism, and a spindle that controls the sealing.
When the 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.
Aboveground Fire Hydrants can be manufactured with 3 different lengths for various pipeline depths.

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.
Shutoff Valve works with hydraulic principles and is controlled by the Prepaid Controller. When open, the valve provides minimum headloss and it provides drip tight sealing in shutoff.
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.
C Type
C 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 4 outlets, enabling supply to more than one farmer from a single hydrant.
