MSA flow control valve P/N 459948 is a high‑precision fluid metering device engineered for reliable, stable performance in medium‑pressure hydraulic and instrumentation systems. With a calibrated flow rate of 1.5 L/min and a maximum rated pressure of 500 PSI (35.5 bar), this valve is ideal for applications requiring accurate fluid regulation under variable conditions—such as lubrication circuits, pneumatic pilot lines, gas tracing, solvent metering, and test‑bench setups.
Made from premium materials including corrosion‑resistant metals and wear‑resilient seals, the 459948 features a precision‑machined metering orifice and adjustable needle mechanism that ensures smooth, repeatable control with minimal drift. Its internal design maintains consistent flow irrespective of pressure fluctuations, while robust valve seats and elastomer seals prevent leakage and enhance long‑term integrity. The compact housing withstands vibration, temperature changes, and abrasive media, making it suitable for industrial, laboratory, and field environments.
Installation is straightforward due to its standard port threading and compact footprint, enabling easy in‑line or panel mounting in tight spaces. The valve’s hand‑adjustable knob is ergonomically designed for fine‑tuning flow, with visible graduation marks that support accurate setup and repeatable settings. Featuring built‑in locking and backlash‑minimizing mechanisms, the valve ensures flow consistency during operation and transport—a critical feature in instrumentation and process control systems.
Engineered for serviceability, the MSA 459948 flow control valve allows quick replacement of internal components without full disassembly. Field‑replaceable seals and valve elements reduce downtime and simplify maintenance tasks. Whether used by instrumentation technicians, maintenance professionals, or system integrators, this valve offers dependable, precise flow control under pressure, backed by MSA's reputation for manufacturing excellence.
