Key Features

• OEM-Grade Valve Construction — Manufactured to Multiquip's original material and dimensional specifications, ensuring correct flow rate, sealing performance, and pressure handling for the 1/2 in. port size.
• Drop-In Port Compatibility — Engineered to match the original 1/2 in. valve connection point exactly, allowing straightforward installation without reworking fittings or lines.
• Broad Series Fitment — Verified for LS, ST, R2000, and FS1 series equipment, covering hydraulic-driven concrete pump, concrete saw, and static roller applications across multiple model codes.
• Fluid System Integrity — A properly functioning valve maintains precise flow control and prevents unintended fluid bypass, which is critical to consistent output and hydraulic or fluid circuit stability on these machines.
• Leak Prevention — Correct valve seating prevents fluid loss at the fitting, protecting downstream components and maintaining operating pressure throughout the system.

A 1/2 in. valve controls the passage of fluid through a specific point in a machine's hydraulic or fluid circuit, opening and closing to regulate flow on demand. On equipment such as concrete pumps and hydraulic-driven machines, this type of valve is essential for directing fluid to the correct circuit at the right pressure and volume. When a valve wears, sticks, or fails to seat properly, the result is fluid bypass, pressure loss, or uncontrolled flow — any of which can compromise machine output or cause damage to connected components.
