NAF-Triball ball valve - 0 for max. bar Fk.6(9)GB 03.03 Primary characteristics NAF-Triball is a full bore ball valve designed for shut-off, on-off functions as well as control application for the metal seated version. The ball valve is made of stainless steel with maximum pressure of bar(e) and in sizes -0. NAF-Triball has 3-piece body, which simplifies disassembling floating ball which makes the valve tight in both directions even at low pressure the stem is provided with an axial bearing washer of PTFE which seals off the media from the packing gland packing gland of PTFE that can be tightened, if necesary, and O-ring of FPM soft seated or metal seated performance lockable handlever in open or closed position valve top according to ISO 51 CE-marked according to Pressure Equipment Directive (PED 97//EG) module H, category III. For module H1, category IV contact NAF Applications NAF-Triball can be used as a control valve (metal seated) or as a shut-off valve, in a wide variety of applications and in different operating modes. The soft seat version should only be used in the full open or full closed position to avoid deformation of the seat rings. One model, NAF 8887x4 can be used for sampling, for example suspended media where the risk is high for valve plugging. In this version the valve is fitted with a special end piece with the same radius as the connected pipework. The valve can be welded to the piping, which enables the ball to be closer to the media, which virtually elimates any plugging.

The operating torque shall be used for selection of actuator. The shown values are the maximum required for operating a valve which has been closed for an extended period of time. For valves which will be operated often, the operating torque can be considarably lower.

Always use great care in disassembling and reassembling the valves to avoid damage to the rings from contamination. After welding, both valves and connecting pipes should be sluiced from welding debris, scale etc. The version with long welding ends, NAF 8883/ and NAF 8863/67 need not to be disassembled before welding. Note that the ball must be in the open position during welding. The length of the welding ends is such that the temperature will not damage the interior of the valve. This is on the condition that welding is done professionally and in accordance with applicable codes and standards. NAF-Triball is simple to disassemble 1. Turn the ball to the open position. Remove one of the bolts (or stud) and release the other three. 2. Remove the body section. 3. Refit the body section after the planned action is carried out and tighten the bolts (or studs). To faciliate dismantling and handling of valves in sizes -0 these valves are equipped with a support flange for the studs which are fitted into clearance holes in the top part of the body. NAF-Triball with short welding ends, NAF 8881/61, must be disassembled before welding. The valve body and its seat rings must be removed as described under the headline "NAF-Triball is simple to disassemble" and replaced with a suitable spacer, such as a body of the same but without internal parts. Screw the end pieces together and weld the unit into the pipe. After welding, refit the complete valve body and tighten the screws to specified torque. 7
Ordering example When ordering a valve please mention data on media, pressure and temperature. If the valve is to be fitted with an actuator, data is also required on max. differential pressure, operating pressure (air) and whether end switches and solenoid valves are desired. Voltage and type of current should be indicated where appropriate. Ordering of spare parts When placing order for spare parts, specify: - NAF-No., and Part No. (see the valve's identification plate) - Quantity required - Description of the part and its item No. (see the Material specification on page 3.) Example NAF 88-00-85, Part No. 7-00 pcs seatrings + seal ring, reinforced PTFE + PTFE pos. 9A Accessories Actuator In its standard version NAF-Triball is equipped with hand lever made of stainless steel with PVC coating. The valve can also be provided with pneumatic or electric actuators for control or on-off operation. Consult your NAF representative for further information. Solinoid valve See datasheet Fk. 79. El. limit switch See datasheet Fk. 79. Other design - Degreased for oxygen All valve parts will be degreased before assembly. Grease approved for oxygen is used. Productcode: D - Drilled vent hole in ball When the media must not be contained. For instance when H/pAA disintegrate, a large power supply is developed. A vent hole is drilled in the ball to avoid that the energy gets contained. The valve is mounted with the arrow in the flow direction. -0 3mm hole.
