Fisher™ Yarway™ AT-38/48 Standard Duty A.T.-Temp Desuperheater

The Fisher Yarway 38/48 Standard duty A.T.-Temp Desuperheater is specifically developed for use on medium / low pressure steam applications.

• The fabricated construction makes it easily adaptable to meet various boiler codes and material specifications.
• The unit can also be used as a liquid into gas injector for which high grade alloy such as stainless steel is often used.
• The valve stem is rolled to obtain a finish of Ra < 0.1 µ. This highly finished surface is then nitrided to give a hardness of > 1000 Vickers. The combination of these processes improves sealing tightness; while reducing packing friction.
• Piston rings are specially hardened and subsequently nitrided and are provided with a special gas tight slot.
• These rings offer excellent running properties and enable controllable Cv (Kv) values as low as 0.005 (0.0043).
