CAT Pumps Pressure Regulator, Nickel Plated Steel, Model 7021, Min. Flow 2.5 GPM-Max. Flow 25 GPM, Min. Pressure 100 PSI-Max. Pressure 1000 PSI


Pressure Regulator 

Model: 7021

This Pressure Regulator is designed for single or multiple pump, weep or multi-nozzle systems. This is a flow-thru design easily plumbed into the discharge line or directly onto the discharge head. This regulator maintains set system pressure even when only one of several guns or nozzles is performing or a solenoid valve is open, by-passing the unused flow. The pressure is held in the line during full by-pass and instantly has full pressure, when all guns and nozzle resume operation. 5-10% by-pass is necessary for optimum performance.


• Stainless steel conical piston and seat extend valve life by providing a consistently smooth flow that reduces wear and compensates for pressure spikes.
• Lightweight, flow-through design allows for easy installation.
• Unique high velocity design ensures consistent pressure for multiple pump or shut-off gun installations.
• Models 7001–7033 have nickel plated steel lower and upper bodies.
• Models 7001.100–7033.100 have 316SS lower bodies and nickel-plated steel upper bodies.
• Models 7001.200–7033.200 have 316SS lower bodies and 304SS upper bodies.
• Stainless steel internal parts for durability and compatibility.
• Standard FPM elastomers for compatibility with many liquids and temperatures up to 240° F.
