Metering Valves use a tapered plug-stem to give a fine adjustment to the flow in addition to a fully open or fully closed shutoff position. The PTFE all-wetted surface design works equally well with ultra-clean DI water and harsh chemical media. As with all Metering Valves, we recommend filtering the media prior to entering the valve. Our Metering Valves come in two configurations: Straight Flow Pattern and Angled Flow Pattern.
Pressure Relief Valves are constructed with a 100% pure PTFE Valve Body and Valve Plug. The single O-Ring design allows user selection of EP, Viton or Kalrez, depending on the flowing media. The Pressure Relief Valve is factory configured for a 10 psi to 90 psi pressure range. The relief valve is fully adjustable within this range by simply adjusting the upper Socket Hex Adjustment Screw and locking in place with the associated locking nut. The Pressure Relief Valve is configured with three Upper Housing and Lower Base options: Polyvinylidene Fluoride ("PVDF"), Polypropylene ("PP") or Anodized Aluminum ("AA") as shown.
