Ball Valves for Fire Protection Systems

2PC Ball Valves for Fire Protection  Brief Introduction The opening and closing part is a  ball , which is driven by the valve stem and rotates around the  stem.The operating part is a handle.The torque input by the handle is transmitted to the ball through the valve stem, causing the ball to rotate 90 °  around the valve stem to open or close the pipeline medium.

installation and use of note: 

① Valves should be stored in a dry room, does not allow outdoor storage To prevent damage to valves and handles ; 

② When in stock, we must ensure that both ends of the protection block intact. If the valve long-term storage should be regularly cleaned, dried, inner anti-rust oil spray. 

③ In the transport process, care should be taken to prevent scratches and casual bump placed 

④ Supply valve in the closed state is 

⑤ Before installing, make clean pipes can not struggle after the welding consumables, welding slag and other debris into the valve, to prevent damage to the valve ball, threaded connections, allowing the use of the appropriate sealing filler.
