END-Armaturen ZA27-EE85

2-way stainless steel ball valve for shut-off of inert gases and liquids. The body is made of a three-part screwed body construction with full cylindrical bore. Due to the self-adjusting, multi-part stem seal, the ball valve is maintenance-free. The ball valve is stamped conform to AD approval and has a fire-safe certification and an anti-static device. A TA-Luft approval is in preparation. The mounting plate according to ISO 5211 enables a direct or distanced mounting of the pneumatic actuators, resulting in an extremely compact and functional unit. Due to the twin-piston system the force developed by the counter-running pistons is transmitted to one common pinion via two tooth racks solidly connected with the pistons. This principle ensures a linear torque transmission along the entire stroke. The function of this ball valve actuator unit is pneumatically double-acting. Further information can be found in our technical portal. The actuator is completely assembled in our factory, adjusted and subjected to a functional test before delivery. Features:

• Mounting pad for actuator with two scribed circles
• Simple, standardized assembly of extensions, signal transmitters or control devices conform with EN 12116 (ISO5211)
• Stem seals with spring washer set and lock plate, maintenance free
• Body parts with centering grooved and tongued, for ease assembly (e.g. after welding)

For higher temperatures above +80°C please refer to the Pressure-Temperature-Diagram in the data sheet. The ball valve is available in many variants and designs and can be ordered online in our shop:

• two sides female threaded connection
• two sides welded connection
• cavity-free sealing system
• Temperature version with pressure compensation bore and ball seals with reinforced carbon fibre
• direct mounted limit switches and solenoid valves

For the use of the ball valve in explosive atmospheres according to Directive 2014/34/EU, a special ATEX version is also available.
