1/4 BSPP Bi-Directional Flow Control Valve

SBA1B is a compact, bidirectional flow‑control valve designed for precise speed regulation in small hydraulic actuators. It uses 1⁄4 BSPP ports and an adjustable needle to meter flow in both directions. Made from steel, the valve measures roughly 54 mm long and 76 mm high, with a 25 mm knob and M20 × 1 adjustment screw. It is rated for flows up to about 25 l/min (≈6.6 US gpm) and weighs only 0.3 kg (0.66 lb). Its small size and low flow rating make it ideal for applications requiring fine control, though pressure drop rises quickly at higher flows.

Five key specifications

• Port size: 1⁄4 BSPP threaded ports for low‑flow hydraulic circuits.

• Dimensions: Body length ~54 mm (2.13 in) and minimum height ~76 mm (2.99 in); knob diameter ~25 mm (0.98 in).

• Flow capacity: Rated for up to 25 l/min (≈6.6 US gpm).

• Construction & weight: Steel body with M20 × 1 adjustment screw; weighs roughly 0.3 kg (0.66 lb).

• Performance: Designed for precise bidirectional flow control; pressure drop increases noticeably at higher flows, suiting it to small actuators.
