With the LEPV Series piston valves Strahman United Process Valves offers high quality environmentally friendly piston valves. The valves offer low emission packing designs, certified to ISO 15848 as a standard. They can be delivered in a wide variety of process sealings that each meet ANSI class VI sealing class. These valves for draining, injection and sampling applications combine the latest sealing techniques and standards with all the advantages of non- clogging and dead space free features of piston valves. The valves are fully customizable regarding materials and type of construction, selected end connections, type of jacketing, and safety features such as purge ports and safety covers. The LEPV Series piston valves replace traditional sampling, drain and injection valves with old fashioned single ring packing design. They are certified to the latest environmental standards, help clean-up production plants while being completely customizable for your specific application.

We offer a unique double sealing design were our soft sealing and metal to metal M-sealing designs are combined in one valve offering long and reliable valve sealing performance for severe applications. In combination with a heating jacket this design works very well for asphalt and bitumen sampling.

To help control the flow through the valve during sampling or injection our LEPV valves are equipped with a flow control function as a standard. The lantern ring is specially machined (drop shaped) to allow control the flow from very small to full flow. This provides operator safety in case of Sampling. Large, sudden (hot or dangerous) flows that may hurt the operator are eliminated). In case of Injection the flow of the injected medium can be controlled.
