Full bore
Double bearing design results in reduction of the friction between the ball and the seat, as well as the elimination of the huge load torque caused by the inlet-end medium pressure pushing the ball to extrude the seat
Relatively low operating torques results in easier operation and lower actuation costs
Spring loaded seat enhances active sealing. In the event a seat is slightly damaged, the seat maintains close contact with the ball, assuring tight sealing. This results in longer service life benefits
Fire safety designed. A metal-to-metal secondary sealing (acc. to ANSI Class IV) is formed in the event the soft seat is damaged
Fire tests acc. to API 607 and API 6FA
V-shaped gland packing acc. to TUV TA-LUFT
Automatic cavity pressure relief
Adjustable stem packing
Valve structure acc. to API 6D.
Optional: Supplementary sealing seat structure. In case of emergency, sealants can be injected into this structure.
