The Multiquip EM97012 Directional Control Valve ST40 is a genuine OEM component designed for the ST40 swing tube concrete pump. As a direct OEM replacement, this valve is built to the exact specifications required to maintain proper hydraulic function in the ST40 pumping system. Sourced directly through Multiquip's authorized parts network, EM97012 delivers the fit and function your machine demands. Confirm EM97012 against your ST40 parts manual before ordering to ensure correct application.
Key Features
- Genuine OEM Hydraulic Specification — Manufactured to the precise flow rate and pressure tolerances required by the ST40 hydraulic circuit, ensuring consistent valve actuation under full pumping load.
- Direct-Fit ST40 Replacement — Engineered to drop into the existing valve block position on the ST40 swing tube concrete pump with no rework to hydraulic lines or mounting hardware.
- ST40 Series Compatibility — Confirmed fitment for the Multiquip ST40 swing tube concrete pump, one of the predecessor platforms in Multiquip's concrete pump lineup.
- Maintains Pumping Cycle Accuracy — A correctly functioning directional control valve ensures the swing tube shifts precisely between cylinders, keeping concrete output steady and strokes synchronized.
- Critical Hydraulic Safety Component — A worn or failed directional control valve can cause erratic swing tube behavior or loss of pump control; replacing with a genuine OEM part restores safe, predictable operation.
The directional control valve on the ST40 swing tube concrete pump governs the flow of hydraulic fluid to the swing tube actuator, signaling which cylinder is active during each pumping stroke. When the valve shifts, it redirects hydraulic pressure to swing the tube from one cylinder to the other, keeping the pump cycling smoothly and efficiently. If this valve sticks, leaks, or fails to shift fully, the result is missed strokes, erratic output, or a complete loss of pumping action — making it one of the most operationally critical hydraulic components on the machine.
