A.RISING STEM RESILIENT GATE VALVE BRIEF FIGURE OF STRUCTURE
Rising Stem Resilient Gate Valves (RRHX)
B.RISING STEM RESILIENT GATE VALVE PRODUCT INTRODUCTION
Rising stem resilient gate valve has general resilient seated gate
valve's advantages and at the same time can show the valve's
opening directly. It can open or close reliably and quickly so is
widely used in fire protection and industry system. Generally, the
valve is installed in the high position to the ground.
