3/4" BSPP Bi-directional Flow Control Valve

SBA4B is a mid‑sized flow control valve from Fluid‑App that uses 3⁄4 BSPP ports and an adjustable needle to regulate hydraulic actuator speed in both directions. It features a steel body measuring roughly 81 mm long and 110 mm high with a 40 mm knob diameter. The valve can handle flows up to about 90 l/min (≈23.8 US gpm) and weighs around 1.1 kg (2.43 lb). Its performance curves show moderate pressure drops across the operating range, providing smooth bidirectional flow control.
