Use JENSEN INERT PTFE CHECK/FOOT VALVES to prevent water backflowing down tubing into wells.

PTFE Check Valves feature all PTFE wetted surfaces for excellent performance in all high purity applications. Design resists chemical corrosion and other elements within harsh process environments. Simple and ideal device where directional flow control is a must. Choose your applicable end connection and cracking pressure.

Stopcock Valves are precision machined devices that function in much the same way as a ball valve. When the handle points in the direction of flow, the valve is fully open; when the handle points perpendicular to the direction of flow, the valve is fully closed; and at the 45 Degree position, the valve is halfway open, and thereby has a metering effect on the media flow. Stopcocks feature an all PTFE wetted surface design. The design is ideally suited for harsh chemical and corrosive media and environments. PTFE is also well suited to clean room and deionized water applications. The body, stem and ports are constructed from PTFE. For standard applications, external non wetted components are constructed from Polypropylene. All configurations are optionally available as Panel Mounted and/or High Ambient Temperature models.

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.
