Everlasting Quick & Slow Opening Blowdown Valves & Repair Kits

Additional Information

Everlasting blowdown valves are engineered for continuous, heavy-duty boiler service. Their unique sliding disc design provides a tight seal, resists erosion, and minimizes maintenance unlike traditional globe valves that wear quickly under sludge and scale buildup. These valves are a trusted choice for power plants, commercial boilers, and industrial steam systems.

 

We stock both quick opening and slow opening valve styles, as well as full OEM-style repair kits to keep your system running efficiently.

 

  • Quick & Slow Opening Blowoff Valves 250 lb, 300 lb, & 600 lb
  • Everlasting Repair Kits: Complete replacement kits with discs, stems, gaskets, and other key components. Extend service life without replacing the entire valve.

 

Everlasting Valve Company developed the self-lapping Flat Rotating Disc metal seated valve in 1911 to handle abrasive slurries in boiler blowdown service. This concept was chosen State-of the-Art lock hopper valve by the DOE for the Clean Coal Technologies program. It is also included in “Best Practices” of a major petroleum refiner for Fluid Catalytic Crackers and Continuous Cat Reformers. Everlasting valves replace installed valves that are repaired more than once a year to increase production and profit. Valve capabilities are vacuum to 10,000 psig, temperature to 1500 F, sizes to 18 inches with pneumatic, manual, or electric actuation and dry solids Bulk Material Valves (US Patent 5,396,919) to 14 inches with pneumatic actuation.

In-stock orders eligible for small-pack shipments placed before 2:00 PM EST, Monday through Friday, will ship the same day. If ordered after 2:00PM EST, it will ship the following business day.
