Type 2652 and 2655 2/2-way Quarter-Turn Ball Valve in stainless steel with pneumatic rotary actuator, DN 10-50

Complete ball valves of Types 2652 and 2655 consist of a pneumatic rotary actuator (Type 2050) and a 2/2-way ball valve. The ball valve body is 2-piece (Type 2652) or 3-piece (Type 2655). The connection between the actuator and the ball valve takes place via a standard interface (fl ange connection). The rotary movement in the drive is produced by a linear piston with quick-acting screw thread coupling. The rotary actuator moves the ball valve through 90° and thus opens or closes the line cross-section. The actuator has an optical display of the piston position. The compact, pneumatically actuated ball valve can be employed for a wide range of applications, even under heavy-duty, slightly aggressive conditions.

Type 2702 2/2-way Angle Seat Control Valve, threaded and weld end connections, 1/2” – 2”

The 2702 Control Valve consists of an 316L angle seat body with a rugged pneumatic piston actuator. The parabolic trim results in a flow characteristic approximately 35% larger than conventional control valves. It is available in either stainless steel on stainless steel or with a durable PTFE seal for tight shut-off. Type 2702 can be actuated by the Continuous TopControl Type 8630 or SideControl Type 1067 and 8635. TopControl/SideControl thus forms a mechanical and functional unit with the pneumatic actuator as a complete control valve system. This system has been engineered for reliable accurate control in applications where high flow rate is an advantage.

Type 2657 2/2-way Ball Valve with manual override, plastic body, DN10-50

2/2-way ball valves with manual override in plastic for separating medium fl ow. There are different body versions and materials can be ordered to suit various applications. As a special feature the ball valves are equipped with the so-called Dual Block® Technology. This system serves as a safety device for the union nuts. It prevents these separating during operation.

Type 2658 2/2-way Ball Valve with pneumatic rotary actuator, plastic body, DN 10-50

The complete unit of the Type 2658 consists of a pneumatic rotary actuator and a ball valve body from plastic. The connection between the ball valve and the actuator is made via a standard interface (fl ange connection). The rotary movement in the actuator is produced by a linear piston with angled thread coupling. The rotary actuator moves the ball valve through 90° and thereby opens or closes the port crosssection. The compact pneumatically-operated ball valve can be used for a wide range of applications and media. The pneumatic rotary actuator can also be used for other purposes. As a special feature the ball valves are equipped with the so-called Dual Block® Technology. This system serves as a safety device for the union nuts. It prevents these separating during operation.

Type 8804 2/2-way ball valve with electric rotary actuator, ball valve in plastic, DN 10-50

The electric ball valve Type 8804 consists of an electrical rotary actuator and a 2/2-way ball valve made of plastic. Different housings and materials are available for various applications. The rotary actuator is compactly built. It can be used also as single device for the operation of other control members (see datasheet Type 3003). As a special feature the ball valves are equipped with the so-called Dual Block® Technology. This System allows you to lock the union nuts in the preset position. It prevents them separating during operation.

Type 8805 2/2 and 3/2-way ball valve with pneumatic rotary actuator

Bürkert's range of precision activated ball valves fulfi l a wide variety of on-off process applications. Available in 2 or 3 way and both single acting and spring return they exhibit high fl ow rates by virtue of their reliable full bore design. Key features include a pneumatic rotary actuator, brass nickel-plated and stainless steel ball valve, external regulation of the pistons, full bore and favourable flow rate.
