Orbit valve

A trunnion mounted ball valve has the ball fixed on trunnions and the seats press against the ball .​ The seats have springs that press them against the ball, the medium assists the springs to seal off on the ball.​

Standard the seats are pressure relieving (SPE), this means the pressure that can build up in the body finds its way past the seat(s). In principal the pressure can go both ways, up and down stream.​
In special circumstances one or both seats can have the double piston effect (DPE), simply stated that type of seat does not allow the seat to move from the ball due to (over)pressure from an unwanted side. Special care is required with regards to safety and installation.​

A trunnion mounted ball valve body can be made of forged or cast material.​ The body can consist of 2 or 3 pieces which can be called: end entry, 2 piece body, split body, 3 piece body.​
Typically available from 2” till very big where the cast version is more limited in size and pressure rating. ​

The available port or bore size is reduced or full. Reduced is normally 1 pipe size smaller (sometimes more) and full is, the same as the pipe size. Check the standards for the actual dimensions.​
Body materials can be almost any, the most common are: forged or cast steel (A216 WCB / WCC, A105, LF2) and Stainless Steel (CF8M, F316). Where lined valves are common with the floating design, in trunnion the valve is high alloy or cladded (strong base material with corrosion resistant layer welded on it)​.
Seat materials typically are: Nylon, Devlon, Teflon (TFE, PTFE, CTFE, etc.), metal (hardened), PEEK, KEL-F (PCTFE).​
If you want to use a ball valve to “control” the flow it can have a cage or drilled pattern in the ball.​ The body parts are typically bolted together but fully welded is possible.

Cameron

Isolation valve for above ground and buried pipeline installations; long-term gas storage facilities; compressor, gathering, and metering stations; gas terminals; residential gas installations; onshore and offshore production and gas and LNG processing; and subsea isolation

Benefits

  • Superior stem sealing performance.
  • Compliant with low-emissions environmental standards.
  • Spherical body design that maximizes strength with reduced weight.
  • Low maintenance.
  • Low cost of ownership.
  • Extended service life and sealing reliability.

Features

  • All-welded construction.
  • Sealing options in self relief (T31) or double piston effect (T32), or a combination of both (DIB2).
  • Double block-and-bleed standard in both closed and open positions.
  • Antiblowout stem design.
  • Thermoplastic seals with no aging effect and no susceptibility to explosive decompression.
  • Belleville springs that maintain constant spring force and protect seat-to-body seal.
  • Robust stem stops that withstand actuator torque.
  • Stem stop viewports that enable verification of proper valve position.
  • Seat and stem injection port with internal check valve.
  • Rotating seats that spread wear over the entire sealing surface for longer service life.

Longer service life

The CAMERON T30 Series valve can be equipped with a mechanism that makes both seat rings rotate at the end of the closing operation. Rotating seat rings are self-cleaning, distribute wear, ensure optimal sealing contact, and facilitate the distribution of any injected flush, grease, or sealant.

CAMERON T30 Series valves are available for pressure classes ASME 150 to 2500 (PN 20 to PN 420) as well as API 2000 to 5000 standards.
Made of forged steel to ensure uniform fine grain structure and toughness, they can be specified in sizes from NPS 2 to 56 (DN 50 to 1400).
These valves are also fire tested to API and ISO standards.

Superior stem sealing performance

These valves include an adjustable and replaceable seal in an antiblowout stem design. In addition, a low-emissions environmental standard design is also available.

Fully welded with a forged spherical body .

The distinctive design of the CAMERON T30 Series valve maximizes strength at reduced weight and improves resistance to pipeline pressure and stresses with less wall thickness. The compact, spherical design also eliminates body flanges, reducing overall size and potential leak paths.

Low maintenance without removing pressure from the pipeline.

Designed to eliminate the need for lubrication, the CAMERON T30 Series valve enables maintenance without reducing pressure or removing the valve from the pipeline.

Low cost of ownership

This valve is designed to minimize material for a lower weight, lower costs for installation and transportation, and minimal maintenance, which improves production uptime.

W-K-M

WKM has been one of Cameron’s strongest brands since its Flow Control Division acquired it in 1987. The name is trusted among engineers in the industry field because of its stellar track record that has remained constant for more than a century. Their line of ball, butterfly and gate valves have repeatedly delivered positive results in many oil and gas and process controls applications, no matter where they are installed. One of the things that make WKM great is that even though their line is in no ways the cheapest, over the course of time their easy to repair design and replaceable parts make their operating costs lower than many other traditional valves that are less expensive at the initial time of purchase.
