27. 1 Orbit vs TruSeal (& Twin Seal) Mechanics of Actuation • Both valves require a lifting motion on the valve stem to disengage the seat and rotate the ball or plug • The mechanical twisting action required to turn the ball or plug is incorporated into the valve stem housing (referred to as the operator housing) • The Orbit valve uses a very steep cam slot (1) which supports actuation Orbit Rising Stem Ball Valve

28. 2 Orbit vs TruSeal (& Twin Seal) • The TruSeal valve uses a shallow cam slot when supplied with a manual handwheel (2) • The shallow cam slot does not support actuation • An automated TruSeal valve must be configured with a 404 Series operator housing, which has a steep cam slot • An existing manual TruSeal valve would require modifications for actuation • The General Twin Seal plug valve can not be actuated with the Bettis GVO linear actuator • Both the lift and twist motion must be generated by the actuator TruSeal Rising Stem Plug Valve

29. Valve Action & Thrust Definition

30. Actuator Design Features The GVO Series of linear valve actuators incorporates the following features: • External tie bars allow contained release of energy in the event of over-pressure and allow ease of inspection and servicing • Spring rod nut is locked to prevents unauthorized disassemble of the spring cartridge • Adjustable travel stop for the rod-retract position; piston bottoms out for the rod-extend position. For specific travel applications, consult factory • Removable mounting pedestal allows field adaption to the valve • Swivel stem connector for ease of installation and stroke adjustment • 70 durometer Nitrile seals are standard, other seal materials available upon request

31. A B Design Features (cont.) • Piston wear band, drive rod bushing and polyurethane rod wiper are standard for all models • Pneumatic cylinder material is hard anodized aluminum, 2” thru 8”, and fiber composite for sizes 10” and above (Chrome plated carbon steel is available as an option). • Cylinder plate and endcap material is carbon steel; optional aluminum for 2” thru 8” • Cylinder plate incorporates a pneumatic distribution groove to maximize break-out thrust • Drive rod material is carbon steel chrome plated; option for stainless steel • Factory finish is Bettis Orange gloss alkyd enamel to RAL 2002 (other colors and coatings available upon request)

32. Specifications and Certifications • The GVO Series of linear valve actuators are designed and manufactured as follows: • Pressure rating of 150 psig MAWP (custom pressure ratings available) • Static pressure test to 225 psig • Standard operating temperature range -23º C to +74º C (-10º F to +165º F) • Low temperature option available, -40º C to + 65º C (-40º F to +150º F) for 2” to 14” type DA • XLT -46º C to + 65º C (-50º F to +150º F) for 16” to 24” type DA and all SR/FS models • High temperature option available, -17º C to + 204º C (+1º F to +400º F) • NPTF cylinder porting, with side porting on the cylinder plate • Actuators designed and manufactured under an accredited ISO 9001:2000 QA program • Consult factory for CE compliant actuators

33. Actuator Types – DA (Double Acting) In DA actuators, the pneumatic or hydraulic supply fluid is required to move the piston both up and down. Air / Hydraulic Air / Hydraulic

34. Actuator Types – SR (Spring Return) In SR actuators, the supply fluid is required to move the piston up. The spring moves the piston down when the supply fluid is removed. Air / Hydraulic

35. Actuator Types – FS (Fail Safe) In FS actuators, the supply fluid is required to move the piston down. The spring moves the piston up when the supply fluid is removed. Air / Hydraulic

36. Bettis Linear Actuator Types • Double Acting • “DA” type • Spring Return • “SR” - Fail Extended • “FS” - Fail Retracted FS SR DA

37. Valve Action & Thrust Output(Springs) • The action of the valve must be matched to the corresponding thrust output position of the GVO

38. Optional Mounting Interface • The GVO linear actuator incorporates a standard open pedestal valve mounting adaption/interface • The welded pedestal is manufactured from 2 steel channels and is removable from the actuator • One end of the pedestal is machined for bolting to the GVO actuator • The opposite end can be supplied as a blank to be machined later and fitted to the respective valve off-site • If the valve top-works are provided with the order, the pedestal can be custom machined by Bettis • The open pedestal allows for easy visual position indication, access to packing glands and is suitable for installing a positioner and/or travel position switches

39. Optional Swivel Stem Connector • The GVO linear actuator can be supplied with, or without, the valve stem connector • If ordered, the valve stem dimensional information would be required and the valve-nut part of the connector would be machined at the factory to match the respective valve stem • The Bettis 3-piece swivel connector allows ease of assembly to the valve stem without the need to rotate the complete actuator as well as allowing for a certain degree of misalignment • The rod-extend travel adjustment (down stop) can safely be made after the actuator has been secured to the valve • Optional features include hammer-blow effect couplings, shear couplings, anti-rotation pin and travel position switch triggers

40. Pedestal with 3 Piece Swivel Connector Assembly • Welded connector • Allows easy assembly to valve stem • Allows travel stop engagement • Triggers limit switches • Allows over-thrust protection (Orbit valves)

41. Manual Jackscrew Override • The GVO Series of linear valve actuators are available with a unidirectional manual jackscrew handwheel override (‘-MJ’) for emergency use when plant air or power gas is unavailable • The ‘MJ’ override can also be used to hold the actuator in a particular position • For models where a jackscrew override is not feasible due to high thrust requirements, dimensional clearance or lack of accessibility, a manual hydraulic override is available • The ‘MJ’ override is not available for type ‘SR’ actuators
