Industrial D1968B6007 Pressure Regulating Valve

The D1968B6007 Ross Controls inline flow-control valve from the 19 Series is a high-capacity, knob-adjustable device used to regulate pneumatic flow in 1" BSPP-line circuits, enabling precise control of cylinder speed in automation systems. As an inline flow-control valve, it throttles air in the circuit to achieve smooth, repeatable actuator motion and is commonly employed in manufacturing, packaging, and material-handling applications where consistent motion is critical. The model features a 1" BSPP (G) port size, a body size listed as 11 1/4", and a knob-style adjustment with a dedicated 007 code that confirms the knob operator. When fully open, the valve provides a flow coefficient (Cv) of 8.3, and the unit weighs about 0.8 kg, reflecting its robust, compact design suitable for tightening into compact piping layouts. The prefix D denotes BSPP threading, per Ross documentation, meaning this version is configured for G-thread connections rather than NPT, and its high-capacity flow path supports higher air throughput without sacrificing control precision. In practice, you’d install this valve in lines feeding pneumatic cylinders to dial in the exact speed for slow, controlled movements or rapid cycling as required by the process, while maintaining consistent performance across varying load conditions.
