Series VLAR VLBR HV High Temp. Angle Valve, Single Acting(N.C)

The VLAR VLBR HV High Temp. Angle Valve series delivers key performance indicators reliability and variability both. Tested in handers of demanding applications under various process conditions the VLAR VLBR series has proven its outstanding reliability and variability.
With its design in actuation pneumatic is available, various flange connections, body materials and sealing materials, nearly every requirement can be met.

The VLAR VLBR is ideal for the 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 VLAR VLBR HV High Temp. Angle Valve offers pneumatic version, it can be configured as single acting with closing spring (NC), opening spring (NO) or double acting. The pneumatic version is controlled by a solenoid valve either “on board” or in a distant location if required.

The pneumatic version is available in sizes from DN 16 to DN 100 mm.

The VLAR VLBR can be selected in stainless steel in various specifications. The standard options for flange connectors are ISO-KF or ISO-K (for the electric version only ISO-KF). The VLAR VLBR can be used in different temperature regimes depending on the sealing elastomer chosen. In addition to these standard options further customization is possible.
