The V21 HV Gate Valve series is equipped with VATLOCK technology which is specially developed to provide reliable sealing without any friction at the gate seal. The VATLOCK mechanism also prevents valve failures thanks to the mechanical lock-in at the closed end position.

Already installed in handreds of demanding applications under various process conditions, the V21 series and its predecessor the V21 have proven their outstanding reliability. They have become the standard for any HV isolation with heating solution requirement in sizes from DN 63-320 mm.

The series V21 provides various actuation and flange connection design options so it’s easily integrated into any HV system. A wide range of special options such as windows and ports ensure optimal fit to the application.

The V21 HV Gate Valve is available pneumatic drive. The valve can be controlled by a solenoid valve either “on board” or in a distant location if required. The solenoid valve’s standard voltage is 24V DC but other voltages are available upon request.  The valve position is indicated with a double position indicator - two switches each for the “Open” and “Closed” positions - with change-over contact.

The standard options for flange connectors are ISO-F, CF-F, ASA-L and JIS. Customer specific flanges with and without water-cooling can be integrated.

The gate sealing can be either an O-ring seal or a vulcanized seal up to DN 200 mm. The vulcanized seal is the recommended solution because of its superior performance in terms of vacuum property and reliability.
