KITZ Graphite and Metal Seated Ball Valves
Technical Data 1. Choice of trim for heated abrasive service
6. Metal seated ball valves (Trim 5H/6H)
Metal seated ball valves are guaranteed for a maximum service temperature of 572˚F (Trim symbol 5H) and 932˚F (Trim symbol 6H). For hard graphite seated ball valves, a maximum service temperature of 932˚F is also guaranteed (Trim symbol 3H). Heat resistant sealing and trim materials qualify these valves for heated abrasive service which cannot be properly handled by conventional soft seated ball valves due to the limited heat resistant characteristics and mechanical properties of their soft seats.
Rigid construction with full metallic contact between the ball and seats, and high durability of trim materials make KITZ metal seated ball valves ideally suited to highly abrasive services handling slurries and other viscous fluids.. ● Trim
Parts
2. Unconditional firesafe provision While metal or hard graphite seats are extremely heat resistant, other sealing components such as gland packing and flange gaskets are made of flexible graphite, another heat resistant material, so that no part of the valve will be affected by extraordinarily heated environments. Also the provision of an anti-static device is not required because of inter-component electric conductivity.

Durable metal seat design and material also provides fully guaranteed throttling service performance, which makes KITZ metal seated ball valves function as a reliable control valve. ● Bi-directional pressurizing. ●
3. Maintenance ease Split body construction of the valve body provides the convenience of easy maintenance, a critical requirement for handling slurries and other viscous fluids.
4. Valve automation Quarter-turn valve drive mechanism makes mounting of valve automation measures such as electric and pneumatic actuators technically easier. KITZ ball valves employ integral actuator mounting pads, complying with ISO 5211 and CAPI, for easy, safe and assured on-thespot actuator mounting without disassembly of valve glands.
Caution: ●
Use a gear operator or valve actuator to fix the valve position when used for throttling service.
7. Hard graphite seated ball valves (Trim 3H) ● Bi-directional

● Recommended
Parts
5. High flow efficiency Full port design provides maximized and linearized flow characteristic with minimal pressure loss as the line flow travels through the valve bore. This is a necessary design requirement particularly for trouble-free service of slurries and other viscous fluids.

KITZ Graphite and Metal Seated Ball Valves
Valve Disassembly and Reassembly for Maintenance* 1. Valve Disassembly 1-1. Work to do before valve dismantling from the pipeline: (a) Relieve the line pressure completely and discharge all line fluids from the bore and body cavity of the half opened valve. (b) Mark the valve end flanges and coupled piping flanges adequately for easy remounting of the valve on the pipeline. 1-2. Work to do before valve disassembly: (a) Remove and collect all inside residue of the valve, if there is any, and record their condition and locations, Subsequent examination of these records may be useful for better valve maintenance. (b) Mark the body-cap coupling flanges of the valve adequately for easy valve reassembly. (c) If flange bolts are found to be seized or stuck, apply some lubricant and leave for a while for easier unthreading on valve disassembly. 1-3. Place the fully closed valve with the body flange down on a work bench, after having disassembled the valve operator, and proceed with disassembly of the cap from the body, referring to the illutrations on Page 37,39 and 41. (No special tool is required.) Be careful not to damage the metal ball seat and ball, which are the most important valve parts. 1-4. After removal of the cap, place the valve body with “KITZ” mark up on the bench, and proceed with disassembly of the ball. Put soft cloths inside the valve body not to damage the ball, which is also an important member of the valve components. 1-5. Examination of the valve component parts: (a) Clean the inside of the valve body and cap, and note any wear, corrosion or cracks in the castings using a magnifying glass, or, where visual access is not easy, using a tube inspector or a mirror and a flashlight. Nondestructive examination may be carried out if found necessary. Measure the wall thickness of castings periodically to check any dangerous signs to jeopardize valve shell soundness. (b) Inspect surfaces of the metal seat and ball carefully to detect any scratches or wear, which may be a cause to replace the seat and/or ball on reassembly. Other metal parts must be also checked carefully to decide whether they are still usable.
2. Valve Reassembly 2-1. Prepare new non-metal valve parts such as gaskets, gland packings, thrust washers, gland bushings, stem bearings and carbon graphite seats, and clean all metal parts before reassembly. 2-2. Proceed with valve reassembly, referring to the illustrations on Page 37,39 and 41. 2-3. Pressurization for Trim 3H valves To assure smooth operation, 21/2” and larger carbon graphite seated valves should be pressurized after reassembly is completed, according to the following procedure: (a) Pressurize the fully closed valve for 60 seconds as follows: Class 150 : 21/2” to 8” : 356 psig Class 300 : 21/2” to 4” : 711 psig 6” and 8” : 569 psig (b) Conduct above valve pressurization from both ends separately. (c) Measure the unloaded operating torgue of the reassembled valve to confirm that the result is within the torque value ranges given below: 6” : 1607 to 3571 inch-lbs 21/2” : 357 to 714 inch-lbs 3” : 536 to 1250 inch-lbs 8” : 2679 to 8036 inch-lbs 4” : 893 to 1786 inch-lbs (d) If the valve operating torque is higher than the maximum value provided above, repeat the pressurization of valves with 71 to 142 psig higher pressure until the correct result is confirmed.
3. Acceptance Test After reassembly, open and close the valve several times to check satisfactory valve operation. Then pressure test the valve according to the specifications given on Page 3 to ensure the satisfactory sealing performance for final acceptance. ＊ Refer to KITZ MT-05 Operation Manual for more information.
