B. RISING STEM RESILIENT SEATED GATE VALVE PRODUCT INTRODUCTION
Rising stem resilient seated gate valve special for fire protection has resilient seated gate valve's advantages. And it shows the valve's opening directly so it's possible to see the valve's opening in a long distance and take effective actions. It opens or closes reliably and quickly so it is often used in fire protection system.
