Triple Offset Butterfly Valve, triple eccentric Buterfly Valves

FREE-Valve’sTriple Offset Butterfly Valve adopt triple offset principle to design, makes the movement track on facing space reach to idealization, and there are no attrition and no intervene between sealing pair , furthermore, the sealing material has been selected reasonably, thereby it ensure sealing performance, wear resistance, high temperature resistancecapability of valve.

Features

  1. Reliablesealing,convenientoperation,openingandclosingfast.
  2. It adopttriple offsetelasticity or multiple layers hard sealing configuration, the hermetical capability can reach to reliable sealing performance.
  3. The seal of disccan bereplaced by loosening the discring bolts, saving the cost of the valve.
  4. According to the requirements of medium conditions, overlaying or spray welding different sealing materials on the sealing surface of the valve seat.

5. Ithascharacteristic ofsuper long usage life, frictionless closure,high temperature etc.
