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.
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.
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.
Y Type Strainers are installed to protect system appliances, such as: pumps, flowmeters, control valves or regulating devices.
The main function is to remove 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, and the user can check the blockage of the filter by using monometer connections.
In case of a situation where the differential pressure reading is high, the blow-off port is used to remove entrapped debris at the bottom of the body.
Y Type Strainers feature large trap capacity, low head loss and ease of both cleaning and handling..

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.
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.
