Brief Introduction


SRRHX fire special resilient seat gate valve is often used in water supply and drainage, building fire systems and other pipelines, especially in the fire pipeline. The signal gate valve can clearly show the status of the valve open and close status, with intuitive, clear and reliable reflection of the fire system in the working state. If the installation position is higher from the ground, usually with a rising stem gate valve, you can clearly indicate the valve opening degree, if the installation location from the ground is low, you need to use gate valve with open indicator.
