Ball valve unit KVZB Characteristics Magnetic reed Operating voltage range 0 ... 175 V DC Max. output current 250 mA Operating voltage range 0 ... 120 V AC Pilot valve The pneumatic pilot valve is mounted directly on the quarter turn actuator via the NAMUR interface. Standard version Poppet valve version A pneumatic pilot valve, with the design principle of a piston slide, is mounted directly on the quarter turn actuator via the NAMUR interface. The piston slide design is the first choice for all standard applications. The technology enables overlap-free switching and, compared to the poppet...

Ball valve unit KVZB Operating position 1-2-3 connected, T-bore 1-3 connected, 2 closed, L-bore 1-3 connected, 2 closed, T-bore 2-3 connected, 1 closed, L-bore 2-3 connected, 1 closed, T-bore 1-2 connected, 3 closed, T-bore Mode of operation Double-acting The double-acting quarter turn actuator requires compressed air for each direction of movement. In this mode of operation, the torque for opening or closing the process valve is generated purely via the compressed air. With the single-acting quarter turn actuator, the incoming compressed air moves the pistons in one direction. This generates...

Ball valve unit KVZB Characteristics Hold position with 5/2B pilot valve The valve is held in the current position if the operating voltage supply fails. This function is only possible with the “double-acting” operation mode and is carried out by a 5/2-way double solenoid pilot valve which remains in the position last occupied before the fault occurred when pressure is applied to one side of the actuator. If the compressed air supply fails, the valve cannot be guaranteed to remain in the current position. Operating pressure The operating pressure available for actuating the quarter turn actuator....
