Types of Check Valves

Boiler Feed Check Valve

Boiler Feed
Check Valve

Engineered to prevent reverse flow in high-pressure feedwater and steam applications, this type of check valve offers double protection with positive and power-assisted closure. Its streamlined design minimizes pressure drops, providing secure flow control.

Compressor Check Valve

Compressor
Check Valve

Trillium Flow Technologies™ compressor check valves ensure rapid, reliable closure during trip-outs or shutdowns, providing positive protection for blowers and compressors. This design offers tight sealing, low-pressure drop, and power-assisted quick closure to minimize operational risks.

Wye Type Check Valve

Wye Type
Check Valve

The wye-type check valve, with its Y-pattern design, minimizes pressure loss and ensures tight sealing with beveled seats. Ideal for high-pressure steam and water isolation, it offers rapid closure, tight shutoff, and reduced valve stem failure.

SUCCESS STORY

Mitigating Closure Issues for Fermi NPP

The Fermi nuclear power plant in Detroit, USA, had issues with wear between seats and disc arm bore in their feed water check valves. Left unchecked, these issues lead to more frequent maintenance needs and potentially costly repairs.

In 2010, Trillium Flow Technologies™ installed two modification kits to feed water check valves, upgrading the disc and arm to a two-piece design, ensuring tight fitting and correct installation as well as simplifying the valve design for eliminated friction and shaft linkage.

FAQS

How Do We Choose a Check Valve?

When selecting a check valve for industrial applications like gas, oil, water, traditional and nuclear power, consider the valve type (compressor, wye, or feedwater), material compatibility with the fluid, cracking pressure, flow direction, and any custom requirements to ensure optimal performance and reliability in specific conditions.

Check valves are made from durable materials such as nickel alloys, duplex and super duplex steels, carbon steel, and stainless steel. Trillium Flow Technologies™ specializes in providing check valves that are resistant to corrosion and wear, ensuring long-lasting performance.

Check valves can be installed both vertically and horizontally, but the choice depends on the type of valve and the specific application. Some check valves, such as our Cold Reheat check valve, are preferred for horizontal installations to avoid bypass steam and water hammering.

Alternatively, vertical installation for spring-assisted check valves, such as our Elbow Down valve, can ensure quick closures. Always refer to the manufacturing guidelines or contact our support team for installation guidance.

The longevity of an industrial check valve can vary significantly based on the quality of installation and maintenance and the operating conditions. With adequate care and optimal conditions, check valves can last decades, and their lifespan can be extended by following servicing best practices.
