Automatic Control Valves
A10B Bi-Level Float Control Valve
Dual-level float control for two-stage reservoir fill.
Product Description
The A10B bi-level float control valve provides two-stage filling: it opens fully at the low-level set point and throttles to a reduced flow rate as the reservoir approaches the high-level set point, preventing overfill surge and pipeline banging at the end of the fill cycle. Suitable for service reservoirs where demand varies widely and single-stage control causes water hammer.
