The MSA flow control valve P/N 459948 is a precision-engineered component designed to regulate fluid flow with exceptional accuracy and reliability. Rated for 1.5 L/min capacity and capable of managing pressures up to 500 PSI (35.5 bar), this valve is ideal for applications requiring fine control of medium-pressure fluid systems, such as lubrication circuits, hydraulic rinsing lines, gas sampling systems, and instrumentation loops.
Constructed from high-grade materials, the valve delivers robust performance under harsh conditions. Its precision-machined internal metering orifice and adjustable needle mechanism offer smooth, incremental flow adjustment, ensuring consistent output rates regardless of pressure fluctuations. Sealed with premium elastomers and equipped with high-pressure valve seats, it minimizes leakage and ensures long-term operational integrity. The sturdy housing is designed to withstand abrasive media, vibrations, and thermal swings, maintaining reliability even in demanding industrial environments.
Installation is straightforward: the 459948 flow control features standard port threading compatible with common instrumentation and hydraulic fittings, promoting easy integration into existing systems. Compact in size and modular in design, it can be mounted in-line or panel-mounted with minimal space requirements. The user-friendly adjustment knob allows technicians to fine-tune flow rates quickly and accurately, while visual flow markings provide repeatable settings and ease of system commissioning or diagnostics.
Performance maintenance is simplified through the valve's serviceable design. Internal components are field-replaceable without specialized tools, enabling fast repair or recalibration. This reduces downtime and supports preventive maintenance schedules. With its ability to reliably maintain 1.5 L/min flow at pressures up to 35.5 bar, it ensures fluid delivery consistency in critical applications where precision matters.
Designed for instrumentation engineers, maintenance professionals, and system integrators, the MSA 459948 flow control valve combines accuracy, durability, and ease of use. Whether used in laboratory setups, process automation, fuel-handling circuits, or test benches, this valve provides dependable flow regulation under medium-pressure conditions—offering both operational stability and long service life in industrial deployments.
