PVC Water stops are profile based on specially formulated plasticized PVC composotion.PVC water stops are used in concrete masonry construction of hydraulic structures to safeguard from hydrostatic pressure & water seepage. It also withstand expansion or contraction of joints & take care of any deflection or displacement arising due to change in temperature or settlement of foundation, eliminating danger of cracks. These are engineered as water tight seals in poured concrete structures.
APPLICATION
IRRIGATION PROJECTS like Dams, Canal, Aqueducts, Siphons
PUBLIC UTILITES like Tunnels, Water tanks, Sewage plants, Swimming Pool,
POWER PROJECTS like Thermal Power Stations, Large Reservoirs
INDUSTRIES like Effluent Treatment Plants, Fertilizers, Refinery, Steel Plant, Retaining Walls
BUILDING like Foundation Slabs, Retaining Walls, Water Tanks

Payment Terms :
PVC Pressure Relief Valve is device which allows water behind a CANAL LINING to flow inside the canal but does not allow canal water to leak in the sub grade. These valves thus protect the lining from damage by releasing excessive hydrostatic pressure behind concrete lining.
Why PVC Pressure Relief Valves requires ?
Canal lining is a thin structure. It is capable of resisting small differential heads but can not counter balance the hydrostatic pressure to which the lining may be subjected during sudden drawdown or when canal is emptied. Therefore necessity of providing Pressure Relief valves & under drainage arrangement arises.
Our Valves are available as per IS:4558 Design.
ADVANTAGES :
• NOVEL DESIGN• VERY SENSATIVE & OPERATE AT LOW
DIFFERENTIAL HEAD
• NEGLIGIBLE BACK LEAKAGE• MODULE IS PROTECTED WITH SCREEN• LONG LIFE• LIGHT WEIGHT• EASY IN CLEANING AS IT IS DETACHABLE• AVAILABLE IN 50mm, 63mm, 90mm, 110mm & 160mm size (FLANGE TYPE & ELBOW TYPE)
PVC longitudinal and transverse (expansion/contraction) joints are manufactured from specially formulated PVC Compound to resist broad spectrum of ozone, oxygen, alkalis and other aqueous born chemicals and to meet diverse nature of concrete lining for long term satisfactory performance when embedded in to concrete structure.
Application
NCLTo be used in canal lining as contraction joint when concrete isin plastic condition.
NCTTo be used in canal lining as expansion joint when concrete is inplastic condition.
