Description:

These high gate valves, manufactured of 304 stainless steel, are inert gas welded, have an easily removable internal mechanism which facilitates cleaning without removal of the valve from the system.  The drive mechanism is designed with an over-center locking device to assure the proper sealing force with the atmospheric pressures from either direction.  This insures that the valve will remain closed in case of air or power failure.  The valve has two types of shaft seals, either differentially pumped, or bellows sealed.  It has a low outgassing rate and a high conductance and can be baked at temperatures up to 200 C.
