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.
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.
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.
B Type
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.

Pressure Reducing
Maintaining hydraulic balance in water transmission and distribution systems is crucial to system efficiency.
Pressure Reducing Valves help accomplish this by reducing high inlet pressure to a lower constant predetermined delivery pressure.
They are the most commonly used control valves.
