Technical Features

Main FeaturesBODY

TRUNNION BALL VALVES

The TRUNNION BALL VALVES design hasbeen conceived with thetarget to grant to final usersthe following advantages:• To permit an easy

assembly and disassembly operation;

• To provide the valves with two independent floating seat rings ensuring the bidirectional tightness of the valve. The seat rings are spring loaded to achieve the required tightness even at very low pressure.

• To avoid any over pressure acting in the body cavity providing each seat ring performing the Single Piston Effect obtaining self relieving function.

• To easily insert in the seats resilient seal insert of every type of material as well as to assembly in the valve METAL TO METAL SEAL.• On request the design

permits to provide modified seat rings

performing double piston effect. • To accomodate

easily special features as per costumerrequest.

The TRUNNION SIDEENTRY are bolted bodyside outlet design to simplify assembly and fieldservice. Perfect sealing and fire safe features are granted by the double sealing action of 0-Rings and graphite gaskets in all static joints of the bodycomponents.

The TRUNNION FULLYWELDED BODY DESIGNreduces the potential leakof bolted design. The bodywelded configuration allowfor a considerable reduction in weigt when the welded end version isselected. Also for this typeof valves the stem extension can be easily provided, making the valvesuitable for inaccessibleareas or buried service.

Also in this case the drainsand grease injectionsystem are supplied.The TRUNNION TOPENTRY BODY is designedfor valves to be maintainedin line. The bolted construction allows disassembly on site forinspection and possible repairs. Disassembling the bonnet cover it is possible to have free access to theball and the seats which can simultaneous be takenout without the need forany special maintenances tools. The valves have standard DB&B design (self-relieving seats)in manner that after maintenances the tightness of the seatingcan be assessed by pressuring the body cavity only.

STEM Fire Safe

Extended Stem


Anti-Static Design

Ball Position

STEM is shaped to be antiblow-out and is axiallysupported by an anti-friction bearing.The stem retention can be provided with two different proven design:A) Depending on the

packing gland.The stem seal is achieved by the use of two O-rings and a graphite gasket retained by the gland plate. An emergency sealant injection facility isprovided between the twoO-rings. The graphite gasketcan be replaced with thevalve in line and the ball inany position. The steamseals can be replaced withthe valve in line providingthat the valve is in the fully closed or fullyopen position and after having completely released the pressure in the body cavity. B) Provided with a

bottom entry shouldered stem.

In this solution the upper stem will be shouldered directly to the body of the valves and can be adopted for side entry fully welded valves and if required by customers specifications.

A spring loaded device is inserted in the stem for granting electrical continuity continually between all the metallic component of the trim and the body.

Trunnion position of the ball is obtained with two, one upper and one lower, rigid, large diameter, short coupled insert whichsupport the ball side load due to differentialpressure. Between the insert and ballis adopted metal-backed, self lubricating sleeve bearing an thrust washers.

RMT trunnion mounted ball valves have been designed to comply withthe fire safety standard of API 607 e API 6FA andISO 10497.Fire safe qualification tests wise witnessed independent inspectionauthority and cover the production range.

For low and high temperature service when the valves to be used on isulated lines or for valves required for low or high temperature service RMT design can include an extended bonnet that increase the distance from the body and the stem sealing area, thus avoiding damage to the seals because of temperature.

RMT valves can be supplied complete with suitable stem extension

for installation on underground lines.

All the drain vent and emergency

seal (and pipes) are extended the relevant pipes are attached to the stem extension.

In addition to standard welding

(BW) or flanged (RF; RTJ) end connection

valves can be suppliedwith hub ends as for

costumer request.

Technical Features

Main FeaturesBODY

The FLOATING BALL VALVESdesign has been conceived with the target to grant to final usersthe following advantages:• To permit an

easy assembly and disassembly operation;

• To provide the valves with two seat Self Relieving that can be provided with: PTFE, PTFE Glass or Graphite Filled, PCTFE (Kel F), Nylon, Peek;

• To avoid any over pressure acting in the body cavity providing a SELF RELIEVING function.

• To easily assembly in the valve METAL TO METAL SEAL.

• To provide the valves with every type of Seal - Nitrile, Viton A, B, GF, AED, GLT and on request Lip Seals

for Cryogenic, High temperature.

N corrosive Application.

•To accommodateeasily specialfeatures as per costumerrequest.

27

The FLOATING SIDEENTRY are manufacturedwith two pieces bolted bodyand closure to allow easy service and maintenance operation on site. Perfect sealing and fire safe features aregranted by the doublesealing action of 0-Ringand graphite gaskets in all static joints of the bodycomponents. The FLOATING valvescan also be provided withFully Welded BodyDesign that reduces the potential leak of bolteddesign. The body welded configuration allow for a considerable reduction in weight when the weldedend version is selected.

For this type of valves the stem extension can be easily provided, makingthe valve suitable for inaccessible areas or buried service, also in case the drains and grease injection system are specified.The FLOATING TOPENTRY BODY is designed for valves to be manteined in line.The bolted constructionallow disassembly on sitefor inspection and possible repairs.Disassembling the bonnetcover it is possible tohave free access to theball and the seats whichcan simultaneous betaken out without theneed for any special maintenance tools.

BALL

STEM

Fire Safe

Extended Stem

End Connection

The FLOATING BALL is made separatelyfrom the stem and is usuallymade in Stainless Steel, orin Carbon Steel ENP, or inSpecial Alloy and in carbidecoating for Metal to MetalService.

STEM is shaped to be antiblow-out and is axiallysupported by an anti friction bearing.The STEM RETENCTIONis provided with a bottomentry shouldered stem. The stem seal is achievedby the use of one primaryPTFE seal, two O-rings anda graphite gasket retainedby the gland. On requestan emergency sealant injection facility can be provided.

A spring loaded device is inserted in the stemfor granting electrical conductivity continually between all the metalliccomponents of the trimand the body.

RMT Floating Ball Valveshave been designed to comply with the fire safetystandard of API:• 607• 6FAand ISO:• ISO 10497.Fire safe qualification test wise witnessed byindependent inspectionauthority and cover the production range.

For low and high temperature service,when the valves to be used on insulated linesor for valves required for low or high temperature service, RMTdesign can include an extended bonnet that increase the distance from the body and the stem sealing area, thus avoiding damage to the seals because of temperature.

RMT Valves can be supplied complete with suitable stem extension for installation on underground lines.All the drain vent and emergency sealant lines are extended, the relevantpipe are attached to thestem extension.

In addition to standard welding (BW) or flanged (RF; RTJ) end connections, the valves can be supplied with hub ends as for costumer request.
