Description
Sant’s bronze Vertical Non Return Valve is supplied in 15 mm to 50 mm. Check valves stop reverse flow without any external operation — line pressure alone opens and closes them. On a pump discharge they prevent backspin and the water hammer that follows an abrupt stop. IBR approved and supplied with the Form III-C certificate required for steam service under the Indian Boiler Regulations. The bronze body gives good corrosion resistance in water service and holds its seating faces over repeated operation. Screwed BSP ends keep installation simple at small bores and allow a valve to be changed with two wrenches. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
