SWT FLOW CONTROLS provide an easy, efficient way to reduce water usage and waste. Choose from machine fabricated PVC Flow Controls, PVC Flange Disc Flow Controls, PVC ANSI Flange Flow Controls, External Backwash Flow Controls, Flo-et Brass and Stainless Steel Flow Controls, and Flo-Controlet™ Flow Controls.

These flow controls are designed for 20 to 120 psid before the flow control. Back pressure after the flow control likely will reduce the flow rate to a gpm below the design parameters of the flow control. Increasing pipe size and drain size after the flow control could eliminate potential back pressure.
 
 
SWT Flow Controls   SWT’s PVC Flow Controls are machine fabricated to exacting standards. They are available with male thread, female thread, or spigot connections to match your application needs. These simple to install units can control liquid flow rates from 0.25 to 20 gpm (0.9 to 75.7 lpm) and are constructed of corrosion-free machined PVC.

Max. Operating Pressure: 150 psi
Max. Operating Temperature: 140°F (60°C)
Materials: PVC & Buna-N (Standard)
Other materials available include CPVC, Polypropylene, PVDF, Kynar, PTFE, Teflon
     
The PVC flow control bodies are
machined and cleaned in the USA.		  
Certifications:
— These parts are machined from PVC bar that is NSF 61 certified and made in the USA.
— Dole-type rubber flow components are NSF 372 for Annex G of NSF 61.
