Blow-off Valves
The primary purpose of a blow-off valve is removal of dirt, sediment and scale. Yarway blow-off valves are available in two broad
categories - those that operate on a sliding principle and those that operate on a seat-and-disc principle. Yarway's Blow-off
Valves conform to ASME Power Boiler Code, Section 1.

Hy-Drop Throttling Valves
The Hy-Drop Throttling Valve is designed for continuous blowdown, but also works well for sampling, high pressure vents, boiler
feed pump bypass relief, high pressure drop services associated with erosive and wiredrawing characteristics-or where velocity
is sufficient to destroy valves of conventional globe or even venturi designs. |
Valve Solutions - Vents and Drains
Plant equipment such as boilers, turbines, and heaters requires vent and drain lines. These lines must be sealed during normal
operation to prevent and loss of fluid. To accomplish this sealing, it is common to install two valves in series on each pipe
line. These two valves working in unison will enable each other to last longer and work better.

Welbond High Pressure Globe Valves
The Yarway Welbond Valve has become an established stop valve for general line service in modern high pressure power plants. The
latest design combines the proven features of its predecessor with advantages made possible by advancements in metallurgy and fluid
flow research. |
