Ross Controls 1968D3014 Flow Control Valve Adjustable Regulator

The Ross Controls 1968D3014 Flow Control Valve is a 19 Series, adjustable regulator with a 3/8‑inch port and BSPP (D‑prefix) threading. In the supply direction it allows unrestricted flow, while the exhaust path provides precisely adjustable throttling to control actuator speed in pneumatic circuits. This model is part of Ross’s family of compact flow controls designed for reliable, inline installation in automation lines, test rigs, and other equipment where controlled cylinder or valve actuation is essential. The D prefix indicates BSPP threads, so this variant uses BSPP connection(s) rather than NPT threads, a detail to confirm when integrating with existing plumbing. Typical applications include speed control of pneumatic cylinders, throttling exhaust in pressure-regulated circuits, and fine-tuning rapid cycling in compact automation assemblies. As a 1968D3014 configuration, it combines a 3/8‑inch port size with the 19 Series flow-control architecture to deliver predictable exhaust flow characteristics and straightforward installation in standard pneumatic manifolds. This makes it suitable for engineers seeking a compact, adjustable flow-control solution that matches common 3/8‑inch port circuits in industrial automation.
