Trunnion Ball

Trunnion ball valves have additional anchoring at the top and the bottom of the ball. Those two trunnions absorb the thrust generated by the line pressure, preventing excess friction between the ball and seats. Therefore, operating torques stay low even at full working pressures.

Anti-Blow-Out Stem Design

Stem design of KFTE top entry ball valves is of blow-out proof which prevents ejection of stem when the valves is under pressure. This design is in fully compliance with API 6D requirements.

Antistatic Device

All KFTE top entry ball valves are equipped with an antistatic device which creates a ground path and ensures an electrical conductivity through all metallic valve components.

Fire Safe

KFTE top entry ball valves are fire safe by standard design. Fire safe tests were carried out and certified according to API 6FA, API 607.

Mounting Flange

KFTE top entry ball valves are provided with ISO mounting flanges for actuators. Their design is in fully compliance with ISO 5211.
