GEM expands its range

GEM Ltd, a wholly owned subsidiary of Thermal Energy International Inc, has launched the GEM Oyster, a unique piston type isolation/stop valve, which overcomes the difficulties usually associated with the replacement of conventional valves or the reconditioning of valve seats on larger sizes.

Traditional isolation valves are sometimes difficult to maintain and can be prone to steam leakage. The GEM Oyster however is efficient, accurate and easy to maintain providing positive 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 GEM Oyster is available in a variety of materials with screwed, socket weld or flanged connections. The piston valve is unique as it enables leaks over the seat or past the stem to be sealed without disassembling, removing the valve from the line or even isolating the process fluid.

A complete set of internal parts can be conveniently and quickly fitted without removing the valve from the line, thereby effectively returning the GEM Oyster to ‘as new’ condition.
