Valves of all kinds from Hawa
 
Ball Valves:
•      Anti-blow out stem: This part, being assembled from the inside of the bonnet, is shouldered and does not bear the strain on the ball.
•      External sealing: Tightness is achieved by O-ring with graphite gasket backup.
•      Solid trunnion ball: Working under full rated differential pressure with no displacement of the ball. Reduces seat wearing. Large bushing ensure a longer life.
•      Self lubricated bearing: Low and constant torque even at high pressure and for large diameters.
•      Seat design : The pressure seal principle of the seat ring, ensures bi-directional Sealing, even at low pressure.The original seat ring design, with piston effect, allows the double in-line sealing (Possibility of bleed valve). Seat pockets are machined in the one-piece body, which ensures a perfect alignment of the seals on the ball. The self-relieving of the body cavity pressure is higher from 0 to 10 % of the upstream Pressure.
•      Top Entry design: One-piece body construction with one single sealing joint, not affected by pipe stress. The number of components has been kept to a minimum in order to simplify assembly and minimize spare parts. Simple dismantling of the bonnet gives access to all internals ( possibility to weld the valve in line).
•      Actuation: The bonnet is a large and robust plate which allows easy mounting of any kind of actuator and steam extension.
 
Check Valves: (Wafer Type / Flanged Ends)
