Lift Check Valves has a disc that lifts up off its seat by higher inlet pressure. When the inlet pressure drops, the disc is closed before the back-flow reaches to the valve, enabling non-slam & drip tight closure.
It has a relatively short valve disc travel resulting in an immediate valve disc closing on no flow conditions, minimizing water hammer and surge conditions.
Lift Check Valve has a center-guided, spring loaded valve disc with a resilient seal, acting over a bronze or stainless steel removable valve seat.
It can be furnished with valve position indicator and electrical limit switches and can be serviced without being removed from the pipeline.
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 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.
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.
C 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 4 outlets, enabling supply to more than one farmer from a single hydrant.
Underground Air Valves that can be buried under soil are designed to perform three functions:
1. Venting of large volumes of air on the start-up of the system, while pipelines are filled.
2. Intake of large volumes of air on shut-off of the system, which pipelines are being drained.
3. Discharge of pressurized air pockets during the operation.
Due to its Stainless Steel Sleeve, the valve can be buried under soil. As a result, no need for an expensive valve chamber is needed.
Moreover, it does not require any external isolation valve, due to its integral automatic closing mechanism. The valve can be serviced from a Surface Box and taken out for cleaning or maintenance.
