Easy-to-maintain

Available from GEM, a wholly owned subsidiary of Thermal Energy International, GEM Oyster is a piston type isolation/stop valve that is described as efficient, accurate and easyto- maintain, providing shutoff and zero emissions.

Suitable for general purpose fluid use and in particular for steam and condensate duty where shut-off tightness is required, the device is available in a variety of materials with screwed, socket weld of flanged connections.

Leaks over the seat or past the stem can be sealed without disassembling, removing the valve from the line or even isolating the process fluid. A complete set of internal parts can then be fitted quickly.
