Neo-Pure Stainless Steel Flow Restrictors can help you save water, energy and money by keeping a constant water flow rate. A flow restrict-or helps your system maintain the flow rate your system was designed for, to give you the best performance.

Specifications:
  • 316 stainless steel construction
  • O-ring: EPDM
  • Orifice: acetal (Celcon)
  • 1/2" FNPT Ports
  • Max Pressure: 150 psi
  • Flow Rate: 4.5 gpm
Why is a Flow Restrictor Important?
Each water system is rated for a certain flow rate whether it is carbon filter, a UV disinfection system, or a water softener. In order for each of these system to remove the contaminants from your water, it will need sufficient contact time with the media for this chemical reaction to occur. More Info

How Does the Neo-Pure Flow Restrictor Work? Flow regulators are used to maintain a defined flow rate regardless of pressure variations of the supply line. Precise flow control improves system performance and in the case of plumbing systems, it provides comfort of use at low pressure as well as water and energy saving at high pressure.
When there is no flow or pressure, the o-ring is relaxed. When there is normal pressure, the o-ring subjected to the line pressure is compressed into the seating area. As the pressure decreases, the o-ring relaxes. The Neo-Pure Flow Restrictor allows for a constant flow over a wide range of pressure variations.

Neo-Pure Stainless Steel Flow Restrictor Applications:
  • Water filtration systems
  • Ultraviolet disinfection systems
  • Water softeners
  • Tankless water heaters
  • Geothermal equipment
  • Distributing machines
  • Electronic faucets
  • Irrigation systems
