Needle Valves open and close by the axial movement of the disc that is connected to a crank and shaft mechanism which the gearbox commands.
When the valve is in fully open position, due to its aerodynamic design, it causes very low head loss and maximum flow capacity.
The disc is guided by circular disc guides deposit welded to the main body, which causes minimum friction loss and stable movement.
Stem, rotated by the gearbox, commands the crank mechanism which moves the disc axially to change the opening area of the valve.
When the valve is in fully closed position, due to special sealing mechanism, drip tight sealing is achieved.
Due to pressure-independent disc operation and special gearbox, torque values needed even in large sizes are minimum.
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.
Maintaining hydraulic balance in water transmission and distribution systems is crucial to system efficiency.
Pressure Reducing Valves help accomplish this by reducing high inlet pressure to a lower constant predetermined delivery pressure.
They are the most commonly used control valves.
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.
Critically acclaimed for raw sewage lines, for shut off service. Eccentricity of the plug (and its turning away from the flow path) is a great feature in allowing (sewerage) solids to pass freely. Sizes and Pressures. Sizes 3” (DN80) to 48” (DN1200) and Pressures of PN10, PN16. Smaller sizes up to DN300 can also be rated PN25
