Resilient Seated

The bonnet type Resilient Seated Gate Valves have a revolving non-rising stem, provided with a functional thread which is inside the valve chamber.
During the operation, stem revolves in the stem nut which carries along a solid wedge which is vulcanized by rubber. Due to its design, low torque values are achieved which eases the revolving of the stem.
The stem is locked against axial movement by a bonnet nut threaded to the bonnet, and no axial movement occurs in the specified conditions.
The wedge is guided in the body in a precast groove and provides an undisturbed water flow when the valve is open.
The body and the vulcanized wedge do not have pressed-in sealing seat. Without the sealing seat, residuals do not collect inside the valve which allows a drip tight closure even in dirty water. Moreover, vulcanized wedge can stretch in case a residual is stuck between the body and the wedge at the time of closure, so that sealing is achieved.

    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.

    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.

    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

    Repair Couplings

    Main focus is in 316L body units which are normally on 2 weeks manufacturing lead. Due to prompt delivery these find major acceptance on site repair works / marine / shut-down works etc.

    Axi-Flex /Stepped Couplings will connect similar or dissimilar pipes, same of differing OD and the wrap-a-round Repair Couplings find favour with end-user like DEWA, ADWEA, EMICOOL, EMPOWER etc. in situation where they experience pipeline cracks and associated leakages.

    Sizes from DN50 to DN4000 but as the size goes up the pressure capability decreases.
