Profile: AEW Valves Pvt. Ltd. is a manufacturer of gate valves, globe valves, check valves, ball valves and zero leak valves. We are ISO 9001:2000 certified. In our gate valves, one-piece design aligns stem accurately, eliminating excessive weight and unnecessary working parts. The bonnet is equipped with stainless bushing which serves as a guide for the stem, and provides back seating when the valve is wide open under pressure. All the components are precision machined. The low center stem to wedge contact in the gate valve reduces the torque considerably. Operation is easy, and the wedge does not stick when the valve is closed hot and allowed to cool. The split-wedge design compensates for minor mis-alignments of seals due to pipe stresses, and makes the valve tight on both seating faces over a wide range of pressures. For cast steel valves, we use C.A.F./spiral wound/gaskets and soft iron gaskets. For stainless steel valves, we use teflon/spiral wound stainless steel gaskets. We use different types of gland packing.
