Yz11x Structural characteristic and purpose
This series reducing valve is direct action membrane type spring reducing valve, it is manufactured and designed on the basis of advantages of foreign same products. It is mainly composed of membrane, valve flap, and adjusting spring. It sense the change of lower stream pressure through the membrane and drive the valve flap, change and control the valve opening to realize the function of pressure reducing the regulating. Set the outlet pressure by adjusting the spring pressure through adjusting bolt The product enlarges the area of membrane and improves the sensitivity. It is suitable for branch pipe of high buildings and apartment.
