Why Choose the Series 1F
True 3-Way Flow Control
Three-port ball design enables L-port or T-port flow patterns for diverting, mixing, or isolating flow between three pipelines — eliminating the need for multiple 2-way valves and reducing system complexity.
Investment Cast 316 SS Body
ASTM A351 CF8M investment cast body with A182 F316 ball and A276 Gr.316 stem. Full stainless steel wetted path provides excellent corrosion resistance for chemical, food, and marine applications.
Multiple Seat & Packing Options
Standard PTFE seats with RTFE and TFM-1600 options for enhanced chemical resistance. TFM-1600 packing and body seal options available. Viton, Kalrez, EPDM, and Silicone stem O-ring choices.
VRS vs. VRS-C - Key Differences
Data Center infrastructure standards and engineering tools.
Data Center Cooling Valves
Precision valves for chilled water, glycol, and CRAC systems with low PUE performance.
Hydrogen-Ready Valves
Series 32 high-pressure ball valves rated to -253°C for cryogenic hydrogen service
