Duo Plate Wafer End Check Valve For Water Works Cast Iron Body SS Disc
The TEKO Wafer check valve is a high performance general-purpose water valve. It is compact in design enabling the installation and pipe work layout expenditure to be considerably reduced. TEKO Wafer type check valves are lighter and smaller compared to conventional swing checks, applicable to HVAC, building service, irrigation, fire fighting and general industry.
|Hinge Pin||Stainless Steel|
|Stop Pin||Stainless Steel|
|Pin Retainer||Stainless Steel|
To avoid premature wear in wafer check valves, please install check valves at a minimum distance equivalent to 5 times the nominal pipe diameter (5 x DN) in straight pipe downstream from any source of turbulent flow. Sources of turbulent flow include the discharge side of a pump, pipe reducers and elbows. The accurate sizing of wafer check valves is crucial to ensure an acceptable pressure drop and a long service life.
Please ensure that flow velocity through the check valve is maintained within the ranges specified in the Pressure Loss Charts
This valve is suitable for use in horizontal installations or vertical up-flow installations. When installing in horizontal pipe work, always install the valve with the hinge pin in the vertical position. When installing between flanges, ensure that bolts are lubricated before assembly and tightened in a cross pattern sequence to achieve an even seal pressure across flange gasket.
