RETEST SFETY The unique KINER sealing system with automatic sealing chamber CERTIFIED QUITY The KINER Ballostar K lives up to its promises eakages represent the worst case for any plant operator. Negative impacts on the environment as well as downtimes, harm to personnel and assets and in some cases heavy financial losses are just a few of the possible outcomes. seal, which therefore practices what it preaches, i.e. a valve capable of reliably fulfilling its shut-off function, is a must. With the KINER Ballostar K, this is ensured in multiple ways: By means of the unique ball valve sealing system and the automatic sealing chamber. This is proven by various tests and certifications for plant operators this means absolute safety in operation with guaranteed tightness. TE SEIN SYSTEM The sleeve reliably keeps the sealing element in the desired position. In the Fire-Safe design, a graphite ring adds additional protection against too high thermal loads. B The diaphragm spring determines the sealing stress for the entire lifecycle of the seal and simultaneously ensures the required pressure of the sealing ring. s a consequence, the seal remains independent of the medium pressure and the flow direction continuously tight. C The sealing ring itself is surrounded on three sides by the springloaded sealing element and can therefore absorb major loads without deformation. C B Valve according to T-uft With a standard value of 0-4 mbar l/s, the KINER Ballostar K significantly outperforms the requirements of the erman Technical Instructions on ir Quality Control. Fire-Safe The Fire-Safe tests in accordance with PI Standard 607, 4 th Edition and EN ISO 0497:004 have been certified by the TÜV ustria. Valve for gaseous fuels Due to its product characteristics, the KINER Ballostar K can be tested as a safety shut-off installation for firing systems in accordance with the European Norm EN 6. Certification for selected types, in combination with special s, can be issued on demand. Operational safety The KINER Ballostar K has a fitting for the installation of a locking device as a standard feature. This negates unintended utilization.. Final inspection certificate In order to ensure quality, application safety and guaranteed tightness for the operator, the KINER Ballostar K is standard-issued with a final inspection certificate on the basis of the norm EN 004.. TE UTOMTIC SEIN CMBER The automatic sealing chamber utilizes spring loads in the two sealing elements for the function of the valve. The result: n automatic sealing chamber, in which the loads of the sealing elements simultaneously work bidirectionally. On the basis of this principle, the TÜV Bayern confirms: The automatic sealing chamber is also capable of replacing two unilaterally sealing standard valves. Primarily, this concerns safety lines in plants, especially those with alternating flow directions. In the case of the KINER Ballostar K, as opposed to conventional ball valves, the absorption area of the medium pressure is not limited to the ball area, but encompasses the entire sealing element (ball and area of the diaphragm spring). In the event of an increase of differential pressure, the additional forces increase as well the preloaded diaphragm springs, which press against the ball, are subsequently relieved and service life further improved. Valve for utilization with oxygen The BM Berlin has approved the KINER Ballostar K for the utilization in combination with oxygen. Valve for gas supply Certificate on the authorization to bear the ÖVW gas quality trademark. Emission testing in accordance with VDI 440 Certified emission testing pursuant to VDI 440 for the K labyrinth stuffing box at room ambient temperature and at temperatures 50 C. Testing of the K O-ring stuffing box (Viton) at ambient room temperature. Standard antistatic The KINER Ballostar K features standardized antistatic equipment in accordance with ISO 7 and EN 98 respectively. n antistatic ball ensures electrostatic discharge from 50 upwards. 06 07
SUSTINBE EFFICIENCY Reliability across the entire lifecycle BOSTR K Overview of types The KINER Ballostar K is characterized by its low costs across the entire lifecycle of the valve (TCO) as well as by its high durability. s a result of its modularity, only affected components need to be replaced in the course of maintenance. This significantly increases the operating time of the valve in the system. For the operator, this means lower costs with regard to plant maintenance, stock keeping as well as installation at continuously high safety levels. With its unique design, the KINER Ballostar K also offers plant operators the flexibility, which dynamic markets demand today: Thanks to a wide range of modular system components, which can be individually combined among themselves, the ball valve can be equipped, refitted or retrofitted for each application case. K-F ong flange design K-FK» 0 Short flange design» SIMPE MINTENNCE WITOUT REMOV FROM TE INE During maintenance and service work, the nuts - need to be removed with the bolt. The remaining nut (4) is only loosened. This allows the core element of the valve to be swung out without major effort and removal from the line, while simultaneously providing access to the two sealing elements in the bore. These can also be easily removed and replaced. Changing the stuffing box seals, removal of the ball and the operating stem (applies to the models K S, SK and ) is also carried out in a very user-friendly manner.

RES OF UTIIZTION Pressure and temperature ranges The pt diagrams illustrate the influence of the three body materials, the sealing materials and the shafts on the area of utilization of the ball valve. This represents safety at the highest level. Insert your operating point into the diagram fields and you will identify whether your safety reserves meet your requirements. t the same time, you will see which parameters may require further change. Carrying out your selection on the basis of this principle, you will optimize the cost-effectiveness of your valve. Maximum for VITON Maximum for PTFE If the operating pressure is between 75-00 % of the nominal pressure, then the application field in all three pressure stages (PN 00, 6 40) will reach down to -0 C. If the operating pressure reaches a maximum of 5 % of the nominal pressure, the safety range of the valve increases to -85 C. ctuator shafts made of the material 4-70 also represent a pre-requirement in this case. Maximum for KFC-5 Maximum for metal / special PN-Pressure (bar) ( bar=0. MPa) 00 If the operating pressure, including load peaks, is between 5-75 %, the field of application increases to -60 C. Cap screws made of the material 4-70 are a pre-requirement in this case. In case the operating pressure drops into the nominal pressure range, the application field in the temperature range will increase. PN 00 PN 6 PN 40 PN 6 PN-Pressure (bar) ( bar=0.

PRESSURE OSSES or p = * * w * 0-5 p = ( Q k v ) * 000 The characteristic unit for shut-off and control valves is the K v -value. The values provided in the table apply to a O flow medium with a temperature of 5 0 C, a density of 000 kg/m and a pressure loss of p = bar at the valve. In metric measurement systems the characteristic unit utilized is the K v -value. In countries using inches, the characteristic unit is described by means of the cv-value. It provides how many US gal/min of water, at a temperature of 60 F and with a pressure loss of psi, flow through the valve. 0
