Variable to Adapts to Any Requirement

The key performance indicators for inline valves are reliability and variability. The 26.5 HV Inline Valve series delivers both. Tested in thousands of demanding applications under various process condition the 26.5 series has proven its outstanding reliability. With its various design options in actuation, flange connections, body material or sealing nearly every requirement can be met.

The 26.5 is ideal for pumping and venting of HV systems when a low outgassing rate is important. It resists high differential pressure and is fitted with a bellows-encapsulated feedthrough for particle-sensitive applications. The bellows encapsulation also prevents pressure peaks in any valve position.

Based on a reliable and robust core design the 26.5 HV Inline Valve offers a variety of design options for actuation from manual to pneumatic and electromagnetic. In sizes from DN 10 to DN 160 mm (0.4" – 6.4") the 26.4 can be selected in aluminum or stainless steel in various specifications. The standard options for flange connectors are ISO-KF and ISO-K.

A visual position indication comes as standard although an electrical indicator can be added as an option. The valve can be controlled by a solenoid valve either “on board” or in a distant location if required. The 26.5 can be used in different temperature regimes depending on the sealing elastomer chosen. The valve can be supplied as normally opened, normally closed or double acting. In addition to these standard options further customization is possible.
