Yarway Slow Opening Blowdown Valves & Parts

Yarway 250 lb and 300 lb slow opening valves are designed for precise control and safe discharge of boiler blowdown and drain lines. These heavy-duty valves are built to withstand high-pressure steam service and prevent sudden system shock by gradually opening to release pressure and sediment.

All Yarway slow opening valves meet ASME and ANSI standards and are available in both 250 lb and 300 lb pressure classes. Replacement parts, including stems, discs, seats, and repair kits, are also offered to extend valve life and maintain reliable operation.

• Boiler blowdown and surface blow systems
• High-pressure steam and condensate lines
• Industrial and commercial boiler systems

Key Features:
• Slow opening design minimizes thermal and mechanical stress
• Rugged cast steel or iron construction for long service life
• Fully repairable with available OEM-style parts and kits
