Midland Industries MFC38N Variable Flow Control Valve 3/8 in

Product Description

The MIDLAND INDUSTRIES MFC38N is a pressure compensating variable flow control valve designed for hydraulic systems requiring consistent, adjustable flow regardless of pressure fluctuations. Built with a cast iron body and a stainless steel rotary spool, this valve delivers a flow range of 0 to 8 gallons per minute (gpm) across a working pressure range of 750 to 3000 psi. The heat treated compensator spool maintains stable flow output as system pressure varies. It is sized for 3/8 inch nominal connections with FNPT (female national pipe thread) ports and a 3/8-18 thread size. This valve is installed by hydraulic system technicians and fluid power specialists in industrial and mobile equipment applications.

The MFC38N is suited for hydraulic circuits where precise, repeatable flow control is required independent of load-induced pressure changes. Typical applications include mobile hydraulic equipment, industrial machinery, and any system where downstream actuator speed must remain consistent under varying pressure conditions. The variable adjustment feature allows technicians to dial in specific flow rates from 0 to 8 gpm to match actuator requirements. Its compact cast iron construction makes it appropriate for high-cycle hydraulic plumbing installations.

Key Features

• Pressure compensating design maintains consistent flow from 750 to 3000 psi
• Variable flow adjustment from 0 to 8 gpm
• Cast iron body for durability in high-pressure hydraulic environments
• Stainless steel rotary spool for corrosion resistance and long service life
• Heat treated compensator spool for reliable pressure compensation
• 3/8 inch FNPT connections with 3/8-18 thread size for standard hydraulic plumbing
• Buna-N seals compatible with common hydraulic fluid types

Compatibility

Designed as an OEM-style replacement or new-installation component for 3/8 inch FNPT hydraulic circuits operating within 750 to 3000 psi and requiring variable flow control up to 8 gpm.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Always depressurize and lock out the hydraulic system before removing or installing any flow control valve. Verify that system fluid type is compatible with Buna-N seals prior to installation. Ensure thread sealant is appropriate for hydraulic service and that connections are torqued according to the equipment manufacturer's specifications for 3/8-18 NPT fittings.
