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).
