The VLAV VLBV HV Compact Angle Valve series delivers key performance indicators reliability and variability both. Tested in thousands of demanding applications under various process conditions the VLAV VLBV series has proven its outstanding reliability and variability.
With its design options in pneumatic drive, various flange connections, body materials and sealing materials, nearly every requirement can be met.
The VLAV VLBV is ideal for compact cylinder design and thus shrink product size while the mounting room of system is minimum. Based on a reliable and robust core design, the VLAV VLBV HV Compact Angle Valve offers different options, the pneumatic version 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 50 mm.
The VLAV VLBV can be selected in aluminum or 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 VLAV VLBV can be used in different temperature regimes depending on the sealing elastomer chosen. In addition to these standard options further customization is possible.
