German standard ductile iron gate valve (RVHX/Z45X-16Q)

　　For a long time on the market use of the general gate valve, the universal existence of leakage, easy to rust phenomenon, the introduction of foreign advanced technology and the production of soft sealing gate valve. Overcome the general valve seal is poor, elastic fatigue, easy to rust and other defects. German standard ductile iron elastic valve seat seal is the replacement of the traditional valve, using the elastic gate produce small deformation compensation, to achieve a good sealing effect, the valve has a light switch, reliable sealing, excellent elastic memory and the use of long life and other significant advantages can be widely used in water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy systems, fluid lines as regulation and closure devices.
