Steam Isolation Valve

The Flowserve Worcester AW44 Series 3-Piece Steam Isolation Valve has been specifically designed for the isolation of steam. With energy costs already high and still rising, the AW44 has proved itself to be cost-effective in minimising the loss of process steam. Using its unique Fluorofill seat material, Worcester guarantees the AW44 on continuous saturated steam service up to 250 psi. (17 bar) whilst other Worcester high-performance seat materials provide even higher temperature/pressure capabilities. In addition to its proven record with steam as a heat transfer medium, the W44 can accommodate other thermal fluids/hot oils up to 250°C (Fluorofill), or up to 280°C where required with other seat materials. The AW44 features a mounting platform on the body for ease of ancillary mounting while retaining valve integrity. For these demanding duties, Worcester incorporates its unique PTFE-coated metal body seal which maintains its sealing capability during thermal cycling. Available in sizes 8-50 mm, the AW44 is manufactured in carbon steel and stainless steel with a range of end connections.
