                  Brief

                  Valve is an indispensable flow control device in national economic fields like petrol chemical, power generation, pipelines, shipbuilding and nuclear. The valve is used to stop, throttle, change pressure or flow of the medium in the pipelines. Valves used in industrial and civil engineering are generally: gate, globe, check, ball, butterfly, throttle, safety and relieve valves.    


                  Based on 20 some years of experience in valves and petrol equipment, Neway is able to offer CNC machines with better cutting performance. High torque and rigidity are the main requirements of valve and petrol equipment. With facing plate installed on Neway horizontal machine center, complicated cutting process is possible. Neway developed efficient gantry drilling center to enable efficient working process of large size valves. Stable CNC equipment assures you with better opportunities, shorter working time and lower cost.
