Global Supply Line are sole agents for Energy Valves complete range of plug valves including:- lubricated pressure balanced plug valves, which include regular and full bore, round port type and double block and bleed twin type in 150 to 2500 class and API 2000 to 10000psi for critical service and abrasive fluids. In addition, Energy Valves also manufacture full circular port compact top entry plug valves for manifold service with metal to metal seating in class 150 to 2500.

The main focus in Australasia are the following categories of specialty valves manufactured in Italy. Energy Valves has extensive experience in these special service valves.

COMPACT TOP-ENTRY PLUG VALVES

The DAFLON plug valve embodies the positive features of both Trunnion Ball Valves and Lubricated Plug Valves. These valves are widely used in the Oil &Gas industry and also in mining applications. This style of plug valve has replaceable bi-directional one piece seats that can be quickly and cheaply replaced. Sacraficial seat materials such as bronze, PTFE, PTFE + metal are available and are ideally suited to abrasive and dirty service. The Daflon valve is also available in a single body dual plug double block and bleed configuration.

The Daflon valve is non lubricated like a trunnion ball valve. However, for oil and gas applications emergency sealant injection facility can be fitted to stem and both seats. The Daflon valve is a full circular port metal seated plug valve for manifolds, wellheads, slurries and other special service applications. This valve does not have to rely on springs behind seats like a trunnion ball valve which could jam or fail. Furthermore, the pressure balanced Daflon valve will not relieve pressure upstream during pressure differentials like a trunnion ball valve so both seats always maintain a seal.

Main features and special executions include:

  • Round port:- full circular port or reduced port, low turbulence and low pressure drop.
  • Firesafe API6FA
  • Top-entry:- repairing does not require removal from the line, internals can be removed without special tools.
  • Electroless nickel plated and PTFE treatment of the bonnet for ease of removal.
  • Lower torque:- The balance pressure inside the valve reduces torque to a lower level than other valves, even in the presence of higher pressures.
  • No danger of plug wedging into the body.
  • Plug plated with chrome (1000Hv), tungsten carbide or Stellite for a maximum service life.
  • The plug can be PTFE/Graphite coated to reduce friction co-efficient to reduce ongoing problems.
  • Emergency seal, provided by an internal sealant path (optional).
  • Plug can be checked to verify possible leakage with valve still under pressure.
  • The body and plug sealing surface is always protected from the flow, assuring a maximum service life.
  • Standard execution for H2S/CO2. Size Dn 2″-3″-4″-6″-8″-10″-12″ full or reduced bore, ASME Pressure Class 150/300/600/900/1500/2500 and API 2000/3000/5000.

Daflon Plug Valves are particularly useful for difficult and dirty or abrasive service conditions for oil, gas and slurries as well as for high temperature applications. Full round port design provides the added advantage of reduced turbulence and reduced pressure drop. These valves are similar to (but not the same as) Texsteam®* style valves ‘D’ series and “Super G’ series. The unique design provides a lower torque, prevents wedging and reduces seat and plug damage problems. These valves are used for use as in compressor stations, mining applications, Oil and Gas pipeline transmission lines as well as wellhead valves.

Trim types available include stellite, tungsten carbide, hard chrome, etc. For abrasive applications, Energy Valve replacement parts prices are often around half the price and delivery time of their major competitor.

Seating types include:- Bi-metal to metal seating, combination metal plus PTFE seating, all PTFE seating, Bronze seating and sinterised Graphite seating. Sacrificial bronze seats are also available. The softer bronze material will avoid damage to the harder plug when debris is trapped between the seat and plug. The low cost one piece bronze seats can then easily be replaced in-line. All seating types are available in ASME class VI shut off (bubble tight). The Daflon valve suits rugged abrasive and mining service with various types of metal seats in class IV and V. Class VI shut off can be supplied when manufactured with Buna-N, Viton or PTFE seating. These valves are excellent for numerous applications that experience sand or particulates that necessitate regular, expensive and time consuming seat and disc requirements. Proprietary Viton (FKM) and Buna-N seats are even harder and more scratch resistant than PTFE.

Petronas have this style of Energy Valves plug valves in service on their wellheads replacing traditional gate valves which were less able to cope with particulates in the product. Being a non lubricated valve, no particulates attract to seats/plugs (a common problem with lubricated valves). This style of valve also offers the advantages of being compact and fast acting quarter turn design. Further advantages are gained in automated applications, as quarter turn actuators are more competitively priced than linear actuators and of course a lower torque enables the use of smaller actuator. The Daflon plug valve embodies the positive features of both Trunnion Ball Valves and Lubricated Plug Valves. These valves are also ideal for service applications where higher temperatures are present in addition to abrasive service.

CAM ACTION SEAT BALL VALVES

Energy Valves patented cam action metal to metal seat, 3 piece body trunnion ball valve is the optimum solution for abrasive service. This valve is a superior alternative to a slurry valve or a full port plug valve. The cam action ‘axial lift off’ seat means this valve has all the advantages of a metal seated ball valve but without the disadvantages. As the valve turns the unique seat lifts off the ball doing the turning motion whilst opening and closing. This reduces torque and prevents seat/ball damage. The cam action seat design prevents jamming and significantly increases the life of the valve. These metal seated valves are normally supplied to ANSI class IV shut off only (class V available on request). Importantly the seat design enables the valves to continue to close off to class IV, even after continued use in abrasive or dirty service applications. This style of valve also offers the advantages of being compact and fast acting quarter turn design. Further advantages are gained in automated applications as quarter turn actuators are more competitive than linear actuators and of course a lower torque enables the use of a smaller actuator. This style of ball valve is suited to mining, slurry and other abrasive service applications where particulates in the media represent a problem for traditional valves.
