Midland Industries MFC12N Variable Flow Control Valve 1/2 in

Product Description

The MIDLAND INDUSTRIES MFC12N is a pressure compensating variable flow control valve designed for hydraulic systems requiring consistent flow regardless of pressure fluctuations. Built with a cast iron body and a stainless steel rotary spool, this valve delivers reliable performance across a working pressure range of 750 to 3000 psi and a flow rate of 0 to 16 gallons per minute (GPM). The heat treated compensator spool maintains stable flow output as system pressure varies, making it a dependable choice for demanding hydraulic circuit applications. Licensed hydraulic system technicians and fluid power specialists are the primary installers of this component.

This valve is suited for industrial and commercial hydraulic systems where precise flow control is essential. The 1/2 inch FNPT connection with a 1/2-14 thread size allows for straightforward integration into standard hydraulic plumbing. The Buna-N seal material offers compatibility with common hydraulic fluids. Typical applications include hydraulic power units, machine tool circuits, and mobile equipment hydraulics where variable flow adjustment and pressure compensation are required in a compact inline package.

Key Features

• Pressure compensating design maintains consistent flow from 750 to 3000 psi
• Adjustable flow rate from 0 to 16 GPM for flexible circuit tuning
• Cast iron body for durability in high-pressure hydraulic environments
• Stainless steel rotary spool for corrosion resistance and precise adjustment
• Heat treated compensator spool for long service life under cyclic load
• Buna-N seal compatible with standard petroleum-based hydraulic fluids

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic systems utilizing 1/2 inch FNPT ported variable flow control valves operating within the 750 to 3000 psi range.

Installation Notes

Installation should be performed by a qualified fluid power technician familiar with hydraulic circuit design and safety practices. Depressurize and de-energize the hydraulic system completely before removing or installing any valve components. Follow applicable OSHA and fluid power industry standards when working with high-pressure hydraulic circuits. Ensure all fittings are leak-free and rated for the system operating pressure before returning the circuit to service.
