Product Description

Trunnion Mounted Carbon Steel Ball Valve With Gear Operation

 

Ball valve of this series has the fixed ball, under any pressure, the ball won't move Under pressure of spring and the medium, push valve seat to realize good sealing ,So valve seat won't suffer too much pressure, has little deformation, small operation torque and long service life. Its service life is 2~3 times of ordinary O type ball valve, which is specially applicable for high pressure and large diameter

 

 Specifications 

  • Temperature Range: -20°C to 190°CMaximum
  • Working Medium: Water, Oil, Gas, Acid, etc
  • Design: API 6D/API 608; DIN3357; EN 13709; BS5351; JIS 2071
  • Inspection&Testing: API 598/API 6D; DIN 3230; EN 12266; BS5146; JIS B2003
  • Face to Face:ASME B16.10; DIN 3202; EN 558; BS2080; JIS B200

 

 Overview 

The trunnion ball valve is a form of quarter-turn valve which uses a hollow, perforated and fixed/supported ball to control flow through it.

A trunnion mounted valve means that the ball is constrained by bearings and is only allowed to rotate, the majority of the hydraulic load to be supported by the System constraints, resulting in low bearing pressure and no shaft fatigue. The line pressure drives the upstream seat against the stationary ball so that the line pressure forces the upstream seat onto the ball to cause it to seal.

The mechanical anchoring of the ball absorbs the thrust from the line pressure, preventing excess friction between the ball and seats, so even at full rated working pressure operating torque remains low. This is particularly advantageous when the ball valve is actuated because it reduces the size of the actuator and hence the overall costs of the valve actuation package.


 Advantage 

Trunnion ball design is the lower operating torque, ease of operation, minimized seat wear (Stem/ball isolation prevents side loading and wear of downstream seats improving performance and service life), superior sealing performance at both high and low pressure (a separate spring mechanism and upstream line pressure is used as the sealing against the stationary ball for low pressure and high pressure m applications).

The trunnion is available for all sizes and for all pressure classes but they are not suitable for throttling purposes.

 

 Application 

The trunnion ball valve is used for cutting or connecting the medium in various pipelines of class150-class2500 and pn16-pn320. It can be suitable for various media such as water, steam, oil, liquefied gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing media, urea and etc. It is widely used in such industries as chemical industry, petroleum, natural gas, metallurgy and etc. The driving modes of the trunnion ball valve include worm and worm gear driving, manual driving, pneumatic driving and electric driving. The trunnion ball valves generally adopt flange connection, and butt-welding connection is also adopted. The seat can be soft seal seat or metal hard seal seat.
