Home > Products > CF Flange High Vacuum Angle Valves > Series VYAP VYBP HV Inline Valve (CF), 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 160 mm.
