Trunnion Ball Valve Manufacturer in USA 

 Valvesonly is one of the top Trunnion Ball Valve Manufacturer in USA. It is called as Quarter turn valve because it used to start or halt the flow in a pipe. It controls the flow in pipe. Trunnion ball valve has a ball which is connected to trunnion in one end and stem on other. The ball is permanently attached to the trunnion so it maintains a good seal on all slides. It is designed for higher pressure applications and make seal better and turn with less torque. Trunnion ball valve maintains the proper seal in both slides and also prevents further tension applied to stem. 

What are the advantages for Trunnion ball valve? 

  •   It can be used for high- or low-pressure applications. 
  •   Trunnion ball valve is better for high-pressure applications in comparison of floating ball valve. 
  •   It comes with drain and bleed connection, allowing for use as dual safe device. 

Types of Trunnion Ball Valve: 

  • Forged Trunnion Ball Valve. 
  • Casting Trunnion Ball Valve. 


The ball is forced against the downstream seat by the in-line pressure in a floating ball configuration, generating the tightness. The ball must be spun against both the in-line pressure and the friction of the seats as it moves from closed to open. In other words, both in-line pressure and the nature of the valve seats contribute to the torque required to operate the valve. When operating pressure or the valve size increases, or when the nature of the seat is made more robust, the amount of torque required increases drastically. The ball is put into a central bottom shaft in a trunnion layout (the trunnion).  

The ball is attached to the stem and the trunnion, indicating that it is not floating but rather fixed. The tightness is caused by the lining pressure pressing the seats on the ball. This means that the ball does not have to rotate against both the in-line pressure and the valve seats during operation, but only against the pressure of the valve seats.
