Balancing Valves
Balancing Valves are used in HVAC applications for flow regulation.
Cartridge type Dynamic Balancing Valves provide constant flow rate at a predefined pressure range, thereby providing equal heating or cooling opportunity for various users.

D Type
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.
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.
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.
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.
Ultrasonic
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.
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.
