Trunnion Mounted Ball Valve C95800 CL150 10’’X8’’

Data Sheet

Two piece construction;

Side entry;

Thick body and bonnet.

We used Teflon Xylon PTFE A193 B7/A194 2H, which is anti-rusting specially used for seawater and so on.

When the valve is closed and the middle cavity is emptied through the discharge valve, the upstream and downstream seats will independently block the fluid at the inlet and outlet to realize double block function.Another function of the discharge device is that the valve seat can be checked if there is any leakage during the test. ln addition, the deposits inside the body can be washed and discharged through the discharge device to reduce damage to the seat by impurities in the medium.

This ball valves 10″(DN250) is designed with sealant injection device on stem and seat. When the seat ring or stem O ring is damaged due to accident, the corresponding sealant can be injected by the sealant injection device to avoid medium leakage on seat ring and stem. If necessary, the auxiliary sealing system can be used for washing and lubricating the seat to maintain its cleanliness.

ln case of fire during the use of valve, the seat ring, stem O ring and middle flange O ring made of PTFE,rubber or other non-metal materials will be decomposed or damaged under high temperature. Under pressure of the medium, the ball valve will push the seat reatainer rapidly towards the ball to make the metal seal ring contact the ball and form the auxiliary metal to metal sealing structure,which can effectively control valve leakage.The fireproof structure design of trunnion pipeline ball valve conforms to requirements in API 607, API 6FA, BS6755 and other standards.

This ball valve is provided with the anti-static structure and adopts the static electricity discharge device to directly form a static channel between the ball and body or form a static channel between the ball and body through the stem,so as to discharge the static electricity produced due to friction during the opening and closing of ball and seat through the pipeline，avoiding fire or explosion that may be caused by static spark and ensuring system safety.

Our trunnion pipeline ball valve adopts the trunnion ball structure and floating valve seat, so as to achieve lower torque under operating pressure. It uses self-lubricating PTFE and metal sliding bearing to reduce the friction coefficient to the lowest in conjunction with the high intensity and high fineness stem.

Our stem adopts the blow-out proof structure.The stem is designed with the footstep at its bottom so that with the positioning of upper end cover and screw, the stem will not be blown out by the medium even in case of abnormal pressure rise in the valve cavity.
