3-Piece Stainless Steel Ball Valves
with PTFE Seals & Seats
by Duda Energy
Duda Energy's Stainless Steel Ball Valves with PTFE (Teflon) Seats & Seals offer excellent corrosion resistance for most applications. Stainless Steel & PTFE work well in applications including but not limited to water, oil, gas/air, light alkali's and acids, biodiesel, fuels and alcohols.
These ball valves are fitted with tight seals to ensure no leakage and a long lasting seal after many years of frequent usage.
Available in both WOG200 and WOG1000. WOG200 are considered ideal for most general applications. WOG1000 are for high pressure and industrial applications where durability and lifetime longevity of the valve are preferred.
Note: Many Chinese manufacturers stamp their valves with "WOG1000" but then cut down on material thickness to save costs. Many stores in America sell these valves as WOG1000 according to the stamp on the valve without knowing that they are not actually of such Industrial Quality. Duda Energy provides true WOG1000 valves which are tested to the necessary specifications to be qualified for handling 1000 psi applications. See our specifications below for a full comparison of the two types of valves.
Descriptions of Different Duda Energy Ball Valve Types
|
Valve Type |
Description |
| 2-Piece Ball Valve |
Full port ball valve which can unthread on one side for service. |
| 3-Piece Ball Valve |
Full port ball valve held together by bolts which can be taken apart for service or removed from the piping without removal of the piping itself |
| 3-Way Ball Valve (L-Type) |
Used to direct flow of a fluid from one set of piping to another alternate set |
| 3-Way Ball Valve (T-Type) |
Like the L-Type, may be used to direct fluid flow to one set of of piping or another. It can also disconnect the main pipe and connect the two alternate pipes together, or connect all 3 together with no blockage. |
