| Manual Valves |
Overview - These valves usually remain in position for long periods of time and may be hard to operate and/or not function as well as when originally installed. This reduction or operability can result from either a loss of effective lubricants in the stem threads, aging of packing, surface corrosion of moving parts, or an accumulation of deleterious solids. Wal-tech recommends scheduled periodic partial or full cycle exercising of these valves. Our sales representatives can customize the best program for your application.
Gate Valves are usually for on-off service. These valves should be operated fully opened or fully closed, never in a partially closed position due to the stress on trim. They usually have very low pressure drop and are used regularly for isolating equipment that may have to be maintained in the
Globe Valves are primarily used for throttling. These valves are designed to operate in a partially-opened position. Several disc designs exist and care should be taken in evaluation the correct design for your application. This should be decided based on the flow conditions of the system. Globe valves are not pressure-reducing valves; they strictly limit the amount of media that can flow through the valve. Wal-tech has the expertise to help repair or pick out the right valve for your application. |
