TECHNICAL FEATURES

Trunnion mounted ball valve

When the ball is in fully closed position, two trunnions absorb the side thrust generated by line pressures, preventing excess fric-tion between ball and seats. With this system, even at full rated working pressure, operating torque stays low. Therefore a gene-rous sizing of trunnions is essential to the life and operability of the valve.The spherical surface is machined and ground to close tolerance. To reduce torque and minimize wear, the ball is then electrolessnickel plated and polished to mirror finish. For special applications the ball may be hardfaced with T.C.C. (Tungsten carbidecoating) to improve resistance to wear and prevent scratching caused by hard particles.

TECHNICAL FEATURESEmergency stem and seat sealant injectionIn case of emergency, when sealing materials (seat sealing and stem o-ring) are damaged or decom-posed by fire or other accidental causes, a sealant injection into fittings on both stem and seat preventsleakage until the primary seal is restored. For Type 54 ball valve the seat sealant injection is an optio-nal feature available with an extra cost.. However, the material between ball and seat is a thermopla-stic, thus no further injection is necessary. Self lubricated, low friction materials is used for stem bea-rings, stem seals and body seats. Low friction materials, e.g. nylon, are used for seat inserts. Stem bea-rings and self-lubricating seals give predictable operating torque for the life of the valve.

StemThe stem is made separately from the ball. It is blow-out proof, property obtained with an integral col-lar in the bottom of the stem.

Stem SealSealing system can be defined triple: two static o-rings seal the stem, plus a third graphite retained bythe adaptor flange. This ultimate seal can be replaced when the valve is in line and in closed position.

Fire safe design and testFire safe is standard design of all Valvitalia ball valve. Two o-ring and gland gasket prevent leakpaths from the valve stem area, o-ring and body gasketprevent leakage through the valve body. If fire deteriorate o-ring, gland gasket, body gasket andthe stem firesafe packing prevent fluid or gas leakage.Valvitalia soft seat ball valve fire safe test(shown in the image) was witnessed and certified according to API 607 - API 6 FA - BS 6755 pt.2.

Anti-static deviceThis device is a standard feature of VALVITALIA ball valves. A coil spring thrusts a little sphere,providing earthed continuity between stem and other metallic components of valve (ball andbody) in order to avoid sparks during tuning of the stem for opening and closing the valve andprevent problems in case of use with flammable fluids and gas.

Seat designType 54 ball valve: plastic polymer insert for seat sealing, spring energised.Type 55 ball valve: primary metal-to-metal seal and secondary synthetic o-ring seal, spring energised.

Body designVALVITALIA trunnion mounted valves have a compact and streamlined body for maximum strength andminimum weight. Uniform fine grain and structure and toughness is assured by forged steel.

Type 54

Type 55

Double barrier on body jointsVALVITALIA valve design assures double barriers for all leakpaths. In this way, when one fails, theother seals.

TECHNICAL FEATURES

Body vent and drainThe drain and vent plug of the valve body enable to check the integrity of the seat ring. A bleed valve may replace the drain plug.

Double block and bleedVALVITALIA design of a valve with two seating surfaces between which the cavity can be vented trough a bleed connection andthus confirm the tightness of the valve, as well in closed position as open position, when pressure is applied to any side or bothsides of the valve.

Double piston effect (55-standard, 54-option)With the DPE seat configuration when there is a leakage in the upstream seat, the pressure entering into the body cavity pushesthe downstream seat against the ball and the valve seals. This effect is a sealing principle involved in utilising line pressure to effect a seal across the floating seat.

First barrier Second barrier

A relief valve is recommended to be installed to protect the body cavity from excess pressure.

First barrier Second barrier

Self relieving seatIn self relieving condition, excessive internal body pressure is automatically relieved both in upstream and downstream line by for-cing the seats away from the closure element.
