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.
