Product Description

summarize
XHZ41 fire special signal elastic seat seal gate valve in addition to the advantages of elastic seat seal gate valve, often used in automatic sprinkler fire piping system, to critically control the water supply pipeline, can be far to indicate the valve opening. Lifting lever gate valve and with the opening indicator gate valve is also often used in the fire system, if the gate valve installation position is higher from the ground, the general use of lifting lever gate valve, you can obviously indicate the gate valve opening, if the installation position is low. It is necessary to use the pay opening indicator gate valve.
