Ross Controls 1968D3014 Flow Control Valve Adjustable Regulator Box

Ross Controls 1968D3014 Flow Control Valve is a 19 Series flow control valve with BSPP (G) threads and a 3/8 in. port, part of Ross’s family that provides unrestricted supply flow and a precisely adjustable restricted flow in the exhaust direction. In pneumatic circuits, it regulates actuator speed by damping exhaust flow while allowing full input to the cylinder, enabling smooth acceleration and controlled deceleration. The model code encodes key specs: 1968 denotes the 19 Series Flow Controls family, D indicates BSPP threading, and the 3 corresponds to a 3/8" port size, ensuring compatibility with standard pneumatic fittings. The 19 Series is described by Ross as providing high air flow into a cylinder and a precisely controlled flow out, making these valves suitable for automation tasks that require repeatable motion and predictable response in equipment, conveyors, and robotics. Available configurations in the line include variations in port size and threading, with the D-prefix models specifically designated for BSPP connections rather than NPT.
