Precautions for Installation!!
The sealing function of BK3 standard ball valves (without“-A” in the ordering number) is valid in only two cases as follows:
(1) The pressure at the closed connection is zero;
(2) Pressure of two connected connections is higher than that of the closed one.

If it is required that all connections can connect a high pressure end (PN2>PN1), it is another three-way valve with special sealing construction and ‘-A’ needs to be added to the end of the ordering number when placing an order.
