So� Seat
With an addi�onal mechanical anchoring of the ball at the bo�om, this kind of valves is suitable for large and higher pressure valves. The ball is fixed, it does not move with the pressure but the seat ring is not. It has the capability to move. Then sealing can be produced on both sides depending on proces requirements. Trunnion ball valves have a complex structure and excellent sealing performance. Trunnion ball valves are designed efficiently to reduce opera�on torque and increase sealing reliability.
CONTROL VALVES Control valves can be used to modify the flow rate downstream for a certain pressure drop across the valve, this means that they are used in uni-direc�onal flow. However, bidirec�onal seat sealing capabili�es can be achieved. Control surface can be placed on the ball or in seat ring depending on the requirements. Different flow control characteris�cs can be achieved like linear, equal-percentage… which express the rela�onship between valve posi�on/opening area and flow rate. Ball valve are much more compact comparing to globe control valves, also for same control capabili�es range ball valves generally are smaller in sizes. Ball control valves usually require smaller actuators to operate them.

Metal Seat
METAL SEATED ABRASIVE
METAL SEATED TEMPERATURE
In severe-service applica�ons where corrosion resistance or abrasion resistance is needed, preven�on in seat and ball is cri�cal. Valves are made metal seat. Metal seats can be hardened by coa�ngs like stellite hard facing, chromium carbide and tungsten carbide. It is possible to use o-rings or thermoplas�c materials as secondary seal.
Seat and ball temperature resistance is cri�cal. Ball and seat are coated by min 150 microns of chromium carbide or tungsten carbide as a standard. Can be also produced with stellited ball and seats. In severe-service applica�ons with high temperatures, it is important to consider metal deforma�ons.
SPECIAL SERVICE HTF Heat Transfer Fluid. Thermoelectric solar technology consists in concentrate the radia�on to heat the fluid and produce electricity. The condi�ons are very strict and exigent because the valve is subjected to temperatures around 400ºC. The HTF pipes carry the heat transfer oil between the parabolic mirrors, the steam plant and the power genera�on circuits. Nowadays, Spain is one of the world’s largest generators of electricity from solar power plants, with a genera�ng capacity of 432MW. Spanish solar energy plants u�lize parabolic trough technology combined with a thermal storage system using molten salt ba�eries to maximize their power genera�ng capacity. For this reason IBOR has design and develop specific ball valves for this service.

Cryogenic
Ibor valves are manufactured for cri�cal condi�ons working at -196ºC in trunnion or floa�ng design. All materials are NACE MR0175 latest edi�on and also impact tested due to low temperature requirements. There are different approaches to select a cryogenic valve. While there are not guidelines choosing the cryogenic valve, there is a trend to select ball valves for their �ght shut-off capabili�es.
LIP SEAL Design of lip seal will vary depending on the applica�on. The main func�ons of a lip seal are to retain lubricants, remove contaminants and separate fluids. Lipseal design made of thermoplas�c sealing with springs. The lips and spring energizer are compressed when installed into the seal cavity. The resilient spring responds with constant force, pushing out the sealing lips. The seal expands when there are pressure in the system, increasing the sealing force beyond that provided by the spring and jacket material. Lip seal design guarantees a good �ghtness, low fric�on seal and a long-life. It is a good alterna�ve where special O-rings are requiered to cover high percentatges of amine or methanol, or where high and low temperatures are too stringent. A specific design for valve is required to maintain the quality.

Trunnion Seat design As line pressure increases, the seat reacts to the force of the pressure to form an effec�ve seal. There are two different designs for the seats of trunnion valves.
Single Piston Effect If the pressure inside the body cavity is greater than the bore pressure then the seat ring will balance both pressures by loosing contact between seat and ball (Fig. le�). Otherwise the seat ring won't let the seat loose contact with the ball (Fig. right).

Valve Concepts An� Blow Out Design Fire Safe Design Ball Valves are engineered for fire safety and successfully fire tested with a metal seal in case the so� seals are destroyed by fire or other means. This is to minimize both external and internal fluid leakage during plant fires, also when sealing are destroyed.
Cavity Relief Based on Single Piston Effect, this op�on allows to relief trapped pressure from the body cavity to the line.
The stem of all Ball Valves has a shoulder that bears against a matching gap in the body or lover to make it blowout proof. The higher the line pressure, the be�er the sealing to atmosphere.
An�sta�c Sta�c electricity builds up inside a valve when the ball rubs against non-metallic seats. This is a fire hazard, especially in flammable fluid pipelines. All Ball Valves have inbuilt an�sta�c mechanisms to provide electrical con�nuity.
The difference between trunnion and floa�ng is the design of the ball and seat.
Valve DBB This feature avoids leaking to the body cavity from both sides of the valve at same �me. The main difference about trunnion and floa�ng is that in the last one is necessary two balls to achieve this feature.
Valve DIB-I Based on Double Piston Effect, this op�on avoids leaking to the body cavity from both sides of the valves and also from the body cavity to any side of the valve. It has the same seat design upstream and downstream. Both seats closed and it isn't produced cavity relief.
Valve DIB-II It is a combina�on of Single Piston Effect for upstream seat ring and Double Piston Effect for downstream seat ring. This feature allows to relief the pressure trapped in body cavity to upstream line and the downstream seat ring helps to ensure no leaking to the downstream line. However the valve is uni-direc�onal.

Available Op�ons Locking Device Locking Device is supplied as op�on in order to prevent opening or closing the valve at line.
Fugi�ve Extension To comply strict emission legisla�on most chemical and process industry plants will have to implement special packings design to achieve required emission levels.
Stem or Bonnet Extension
Can be used, Stem extension to sa�sfy any underground or insula�on installa�on needs, or Bonnet extension to sa�sfy any specifica�on of temperature.
Integral Nipple Valves can be supplied with integral nipples to achieve welding without damage on the valve.
Sealing Injector The func�on of S.I. is allowing an emergency sealing in the remote event of damage to the so� seat inserts.
Oval Safety Handle The oval handle is a lowprofile opera�ng device that eliminates “lever” ac�on and helps to prevent unwanted opening of the valve.
Hea�ng or Cooling Jacket One challenge is maintaining the fluid produced in industrial lines at a specific temperature so that its proper�es can be conserved during the process.
Deadman There is a risk of leaving a ball valve fully or par�ally open. The deadman is a principle which released the valve lever automa�cally causing the clousure of the valve.
