GEM EXPANDS ITS RANGE WITH UNIQUE PISTON VALVE

Total solutions service for maintaining and minimising the cost of running steam and condensate applications

Dedicated to providing its customers with a total solutions service for maintaining and minimising the cost of running steam and condensate applications, 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.

Available in Cast Iron, SG Iron, Carbon or Stainless Steel, the GEM Oyster is classed as ‘soft seated’ and provides class 6 isolation.  With the GEM Oyster there is no requirement for double isolation, unless stipulated to meet site/local standards, as the valve provides 100% tight shutoff under all conditions.  The GEM Oyster is available in all sizes ranging from 3/8th” to 2” for the screwed option and ½” to 8” for flanged piston valves. 

The GEM Oyster further expands GEM’s growing arsenal of products that help companies and institutions reduce energy costs and carbon emissions.  Other products available include the company’s Flu-Ace waste recovery technology and the award winning GEM venturi orifice steam trap range.
