SOLBERG Hydraulic Concentrate Ball Valves come in standard sizes ranging from 1.0 in to 2.5 in (DN25- DN65) to match the concentrate inlet thread (or flange) size on SOLBERG Proportioners and Inline Balanced Pressure Proportioner (ILBP) assemblies. Each ball valve consists of a factory assembled and tested stainless steel or bronze ball valve, stainless steel hydraulic actuator, and mounting kit attaching the actuator to the ball valve. The actuator has a position indicator for manual reset.
