Sleeve Valve

Size (mm) : 200-2200
Pressure rating : 6-65 (bar)
Body Material: All Types of Carbon Steel
Sleeve Material: Stainless Steel

This valve is commonly used as discharge valve at the end of pipeline, dams and hydro powers. In addition to needle (plunger) valve and fixed con free discharge valve, Sleeve valve is applicable for dissipating energy of water, isolating and throttling at the end of storage tanks pipeline.
This valve is able to maintain the flow rate on a constant value for a long time or discharge great volume of fluid during flood time in order to decrease stresses on dam walls.

Paint Coating :
Electrostatic epoxy powder (RAL 5005 or 5015) with min. thickness 250 micron.

Application :
Sleeve Valves are used as on – off & also throttling discharge equipment in dams, power plants & pipelines.

Operation :
This type of valves are positioned on a concrete pedestal & inject water from special form of valve downstream.

Injection of water to concrete wall that are reinforced by stainless steel plate cause smashing of the high level of water energy & lead to over flow from pond slowly
