Ordering Information

Ball Valve Configuration
( During the ball valve’s switching process, the various ports will be temporarily interconnected.）

Installation Note!!

1)The sealing function of standard BK3 ball valve (without "-A" in ordering number suffix) is only valid when port PN1 is always connected to sides with lower pressure than the other ends.
2) If all ports are required to be connected to high-pressure sides, "-A" must be added to the end of the ordering number.

Application of Sealing Materials

Type	Material	Uses
Metal Materials	304 Stainless steel	For use with water, air, and mildly corrosive media, at temperatures ranging from −196°C to +400°C.
Metal Materials	45# Carbon steel	For standard hydraulic systems with no special material requirements, the surface is galvanized, and the operating temperature range is −45°C to +250°C.
Seat Sealing Material	POM	Primarily used for non-corrosive oils, water, and gases, with a temperature range of -35°C to +100°C.
	PTFE	Excellent corrosion resistance, suitable for most media, temperature range: -40°C to +150°C.
	PEEK	It exhibits excellent corrosion resistance and a wide operating temperature range, from –50°C to +230°C.
O-ring	FPM	Resistant to acids, alkalis, and benzene-based solvents; suitable for most media; not resistant to ammonia; operating temperature range: -25°C to +180°C.
	EPDM	Suitable for ammonia, steam, alcohols, ketones, and aldehydes; not resistant to mineral oils; temperature range: -45°C to +130°C.
	NBR	For non-corrosive media such as oil and water, with a temperature range of -35°C to +100°C.
