Note, The sealing function of the BK3/SK3 standard ball valve is only valid in the following two cases:

(1) The interface pressure that is turned off is zero;

(2) The pressure of the two connected interfaces is higher than the pressure of the closed interface;

If all interfaces are required to be pressurized (PN1=PN2), or a three-way ball valve for gaseous media, then

Another three-way ball valve with special sealing structure should be marked with “A” after the model.

*The ball valve of the DIN2353 interface type can be equipped with a welded joint to become a welded ball valve, as shown on the right.

Ordering example W-BK3-15L×2 13 1123 (See the table above for specific model sizes)

“W-” means welded type, “15” means welded outer diameter RA is 15mm

"×2" indicates that the wall thickness S of the welded joint is 2 mm.

**Ball valve with snap-on interface is also available (DIN2353), as shown on the right

Ordering example C-BK3-15L 13 1123 (See the table above for specific model sizes)

“C-” means ferrule type, “15” means outer diameter RA of steel pipe is 15mm

BK3 three-way high pressure ball valve with interlocking handle (please inquire when ordering)
