Can the MSI valve be greased under pressure?
|
|
|
|
Summary: Grease fittings are rated to the full working pressure of the valve assembly and can be used to grease the valve when it is under pressure. In fact, MSI encourages this practice when conditions such as high temperatures, distillates/condensate, and frequent cycling warrant frequent greasing. This requires a grease gun/pump that can safely achieve pressures higher than the line pressure of the valve. It must be noted that conventional plug valves can only be greased in the open position. Only GreaSeal plugs exclusively available from MSI allow greasing in any position. Please see section 1.0, step 29 of the valve manual.

Do you offer High temperature valves, fittings, chokes, manifolds, etc?
|
|
|
|
Summary: Equipment operated at either extreme of the temperature range will usually require special seals and grease. If temperatures above 130 F are expected then high temperature grease and HSN plug and resilient seals should be considered. If temperatures below 30 F are expected then low temperature grease and Buna plug and resilient seals should be considered. The presence of certain gases such as CO2 at high temperatures make use of special seal mandatory.
