Ball Valve Sealing Material Table | ||
Category | Material | Application |
Ball seat seal | Polyformaldehyde(POM) | Mainly used for non corrosive oil, water, gas, -30 ¡æ to +100 ¡æ |
PEEK | It has good corrosion resistance and a wide temperature range, -60 ¡æ to +250 ¡æ | |
O-ring | Nitrile butadiene rubber(NBR) | Used for non corrosive media such as oil, water, air, etc. - 35 ¡æ to +100 ¡æ |
Fluororubber(FPM) | Good chemical adaptability, suitable for oil and concentrated acids, -25 ¡æ to +200¡æ | |
Ethylene-propylene rubber(EPDM) | Used for ammonia, steam, formaldehyde, ethylene glycol, not resistant to mineral oil, -50 ¡æ to+130 ¡æ | |
Basic Ordering Number | Internal diameter (mm) | D | L(mm) | A(mm) | B(mm) | Maximum Working Pressure (bar) |
BTH-G1/8-04F | 4 | G1/8 | 69 | 55.5 | 107 | 300 |
BTH-G1/4-06F | 6 | G1/4 | 69 | 55.5 | 107 | 300 |
BTH-G3/8-08F | 8 | G3/8 | 69 | 55.5 | 107 | 300 |
BTH-G3/8-10F | 10 | G3/8 | 73 | 58.0 | 107 | 300 |
BTH-G1/2-13F | 13 | G1/2 | 85 | 59.0 | 107 | 300 |
BTH-G3/4-20F | 20 | G3/4 | 96 | 78.0 | 160 | 200 |
| BTH-G1-25F | 25 | G1 | 115 | 79.0 | 160 | 200 |
The working torque of the ball valve depends on the pressure and the sealing material of the ball seat. The working medium in the figure is oil, and the seal is POM (if water*1.2 times, air*1.4 times;granular powder*1 .6 times)actuator torque =1.2*torque ( 1.2 is the safety factor) |
