Standard screwed: NPT, BSP
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.
