Product catalog summary

Overview: The document provides detailed specifications and configurations for the BK3-S series selector ball valves made of steel. These valves are designed for various industrial applications and are available in multiple sizes and connection types.

Specifications:

Materials: The body, ball, and stem are made of steel, while the ball seats are made of POM and O-rings are available in NBR and FPM.
Temperature Range: The operational temperature range is from -20°C to 100°C.
Pressure Ratings: The valves are rated for pressures up to 500 bar, depending on the material and porting pattern.

Available Sizes: The valves are available in sizes ranging from DN4 to DN50 (1/8" to 2").

Connection Types: The valves support various connection standards including DIN ISO 228 Female thread, ANSI B1.20.1 NPT Female thread, and others upon request.

Accessories: Optional accessories include locking devices, actuators, mounting holes, position switches, and detent combinations.

General Dimensions: The document provides detailed dimensions for each valve size, including length, width, and weight.

Flow Characteristics: The flow characteristics are depicted in a graph showing the relationship between flow rate (Q) and pressure drop (ΔP) for different valve sizes.

Porting Patterns: The document specifies porting patterns L=SB55 and T=SB56, with further patterns available on additional pages.

Assembly Threads: The valves are compatible with ISO 5211 assembly threads, with specific dimensions provided for each size.

Important Notes: Pressure inlet is possible from all ports, but the valves must be operated only at ΔP=0 bar.
