Hydraulic systems design is the disciplined process of converting prime mover energy into precisely controlled mechanical motion through pressurized fluid. The direct conclusion up front: a reliable hydraulic system is built on four decisions made in order — set the working pres...

What Valve Actuator Sizing Actually Means The correct answer to “how big should my valve actuator be?” is simple: the actuator must deliver more torque than the valve asks for, at the worst point of the stroke, at the lowest supply condition you can guarantee. Every good sizing ...

The Bottom Line on Quick Couplers Under Pressure A hydraulic quick coupler that refuses to move is rarely a mechanical fault in the coupler itself. In most cases, residual pressure trapped in the line is pressing the internal poppet against its seat, and the sleeve cannot retrac...
