Ball O Matic 3-way
3 - way ball valve heavy series for actuator
Ball · o · matic has been designed to fulfil the most extreme and demanding applications.
Like the 2-way version, the valve is equipped with a triple-sealed “explosion-proof” pin on the stem consisting of a main PTFE gasket, an O-ring and an anti-friction ring. The ISO 5211 flange guarantees full compatibility with standard market actuators.
BOM valves are suitable for cold and hot water, compressed air, oils, hydrocarbons and non-corrosive fluids.
The valve is available in sizes from ¼ "to 2".

TRIPLE SEALING BLOW OUT-PROOF STEM
BALL O MATIC 3 WAY ball valve is bottom loaded stem designed to prevent blow-out, with a triple sealing: in the upper part one stem packing in PTFE and one O-Ring in elastomer; an anti-friction thrust washer in PTFE in the lower part.
The patented and automatic system guarantees a perfect tight seal in any working condition, maintains pressure constant on the seats and, by taking up slackenings, avoid any need for maintenance.
BALL POSITION
Ball position can be identified by referring to the notches shown in the stem.
The lever can be positioned in 4 different sectors, as shown in the following chart:
| SIZE | 1/4” | 3/8” | 1/2” | 3/4” | 1” | 1”1/4 | 1”1/2 | 2" | |
| DN (mm) | 8 | 10 | 15 | 20 | 25 | 32 | 40 | 50 | |
| PN MAX (bar) | 40 | 40 | 40 | 40 | 40 | 40 | 25 | 25 | |
| Kv (with water) | - | - | 5,4 | 8,6 | 15,6 | 30,3 | 52,6 | 73 | |
| MAX BREAKING TORQUE (Nm) | PN Ø T 25°C |
6 | 6 | 7 | 8 | 11 | 16 | 25 | 30 |
The above mentioned values are indicative (statistic average) and refer to a valve new, as released by ENOLGAS after seven days standstill, at the temperature of 25°. Please consider eventual safety margin in case you might use the valve with different actuators.
