Series VLAP VLBP-G HV Angle Valve, Double Acting
The VLAP VLBP-G HV Angle Valve series delivers key performance indicators reliability and variability both. Tested in thousands of demanding applications under various process conditions the VLAP VLBP-G series has proven its outstanding reliability and variability.
With its design options in actuation from manual to pneumatic to electric, various flange connections, body materials and sealing materials, nearly every requirement can be met.

The VLAP VLBP-G 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 VLAP VLBP-G HV Angle Valve offers different actuation options. The manual version is controlled by a removable hand wheel that provides good grip and precise control with a clear end stop position, avoiding the risk of over twisting. 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 electric version is actuated by a stepper motor supplied as normally closed using a 24V DC power supply. It is designed to meet specific requirements in low power consumption, high cycle time, reduced vibration and low noise. In this regard it is an alternative for applications where pneumatic actuated valves do not satisfy these objectives.

The manual and pneumatic version are available in sizes from DN 16 to DN 320 mm.

The VLAP VLBP-G 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 VLAP VLBP-G can be used in different temperature regimes depending on the sealing elastomer chosen. In addition to these standard options further customization is possible.
