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.
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
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.
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.
Dismantling pieces
Dismantling Joints allow easy installation and removal of valves from the system during maintenance.
By using the bolts on the product, the user can create a work space in the longitudinal direction and can work easily on the valve that is connected after the dismantling joint.
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.
