Machined from lightweight aluminum and finished with clear anodizing, the valve uses inverted flare bubble (BF) 10 mm x 1.00 female inlet and outlet fittings and a user-friendly knob to dial in pressure from 100 to 1000 psi. It is intended for integration into hydraulic brake systems where precise modulation between circuits is required.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the knob adjust brake pressure and bias?\u003c\/h3\u003e\n\u003cp\u003eThe rotating knob changes the internal metering to alter downstream pressure and therefore brake bias between front and rear circuits or other split systems. Adjustment is continuous throughout the torque range, letting you incrementally increase or decrease line pressure without disassembly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eKnob operation for tool-free tuning while installed\u003c\/li\u003e\n  \u003cli\u003eAdjustable span: 100–1000 psi for broad tuning capability\u003c\/li\u003e\n  \u003cli\u003eFine-thread internal mechanism for predictable response\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat fittings and installation considerations should I know?\u003c\/h3\u003e\n\u003cp\u003eThis valve uses 10 mm x 1.00 female inverted flare bubble (BF) connections at both inlet and outlet, matching many performance brake hose and hard-line terminations.
