Hunter Industries PMR-20-MF-3F3FV Pressure Regulator 20 Psi

Product Description

The HUNTER INDUSTRIES PMR-20-MF-3F3FV is a inline pressure regulator designed to maintain a steady 20 PSI downstream in irrigation and water distribution systems. Rated for flow rates between 2 and 20 gallons per minute, it accepts 3/4 inch female iron pipe thread (FIPT) connections on both inlet and outlet. This regulator protects downstream drip emitters, sprinkler heads, and lateral lines from pressure fluctuations that cause uneven distribution or component failure. It is installed by irrigation contractors, landscape professionals, and plumbers working on residential and light commercial irrigation systems.

This regulator is suited for use in drip irrigation systems, subsurface irrigation, and low-volume sprinkler zones where pressure control is critical to system performance. The 2-20 GPM flow range accommodates a wide variety of zone sizes, from small drip manifolds to larger rotary head laterals. Its 3/4 inch FIPT connections make it compatible with standard schedule 40 PVC and threaded poly pipe fittings commonly used in irrigation mainlines and submains.

Key Features

• Regulated output pressure of 20 PSI for consistent downstream performance
• Flow range of 2 to 20 GPM suits a wide range of zone configurations
• 3/4 inch FIPT inlet and outlet connections for standard threaded pipe compatibility
• Inline installation keeps the regulator within the mainline or submain without added fittings
• Lightweight construction at 0.44 pounds reduces load on threaded connections

Compatibility

Designed as an OEM-style replacement or new-installation pressure regulator for residential and light commercial irrigation systems using 3/4 inch threaded pipe connections.

Installation Notes

Installation is performed by licensed irrigators, plumbers, or qualified landscape contractors. Shut off the water supply and relieve system pressure before threading the regulator into the line. Use thread seal tape or pipe dope on all FIPT connections to prevent leakage. Follow local plumbing and irrigation codes for buried or exposed installations.
