Mil-spec valves must meet many high standards for operation in the field. One of the most important standards is durability. A pressure relief valve’s durability informs more than just how reliably and consistently it performs its critical functions. It also influences longevity, lifetime operating costs, and other factors. In a stressful maritime environment, a mil-spec valve’s durability is one of its most essential qualities.
Since the 1980s, Dante Valve’s Danco product line has met and exceeded the high standards for quality and performance demanded by the US Navy and our maritime allies. Our valves provide pressure relief and prevent damage to equipment and injury to personnel from overpressure in the most rigorous and demanding shipboard environments. In this article, our expert technicians will walk through the features of our pressure relief valves to demonstrate how durable Danco valves are.
Examining Danco Valves’ Durability: The Secrets to Pressure Relief Success
Precise, expert engineering, design, and support are key to creating durable Danco relief valves that can stand up to the demanding conditions of naval and marine environments. You can trust Danco pressure relief valves to reliably and consistently provide safe operating environments over a long service lifetime, because Danco valves are:
Quick-Acting
Danco valves respond rapidly to pressure changes, preventing dangerous overpressure situations and protecting shipboard systems from potential failure or damage. Our products’ quick-acting features contribute to mil-spec valve durability by providing continuous operational stability in high-pressure environments and preventing excess wear on not only upstream and downstream equipment but also the valves themselves.
Non-Chattering
Danco valves’ durability is also owed to their non-chattering performance. “Chattering” refers to unwanted rapid opening and closing cycles that cause excessive wear. With sturdy designs to prevent chattering, Danco valves reduce stress on internal components and extend valve life, while also preventing damaging vibration and noise that can compromise system integrity and shipboard safety.
Smooth-Guiding
Durable military-grade valves like our line of Danco relief valves are smooth-guiding to reduce friction and prevent valve components from sticking or jamming. These features ensure consistent pressure regulation in shipboard applications, even in extreme conditions.
Built From ASTM-Rated Materials
One key aspect of Danco valves’ durability and reliable functionality in a range of high-pressure and high-temperature environments is their material construction. Danco valves are built from materials like stainless steel and bronze that meet ASTM (American Society for Testing and Materials) standards for strength, corrosion resistance, and thermal stability.
ASTM-rated valve bodies, discs, and springs can more reliably withstand harsh marine environments, including exposure to saltwater, high humidity, and extreme temperatures, to prevent premature failure.
Designed with Unique Soft-Seat and Hard-Seat Designs
Depending on their applications, Danco valves use either soft seats (for fluid systems) or hard seats (for high-pressure and high-temperature systems) to optimize performance and ensure long-term reliability even under harsh operating conditions. Danco valve seats are uniquely designed to provide significant sealing advantages over other military-grade valves.
Wire Sealed to Prevent Tampering
Unauthorized adjustments to mil-spec relief valves can severely compromise their performance and overall system safety—in addition to voiding warranties. To ensure both compliance with strict naval and military operational protocols and lengthen service lifetime, Danco valves are sealed to maintain factory-set pressure relief settings.
Warranty-Protected
All Danco valves are backed by a two-year warranty guaranteeing materials and workmanship against defects, reducing lifecycle costs and downtime associated with defective components.
Customized Materials
Certain Danco valve models, such as the Stainless Steel Exposed Spring Full-Nozzle Pressure Relief Valve, can be assembled with custom ASTM-rated materials for their body, stem, spring or disc assembly, allowing for material selection based on the ship’s specific operating environment or to ensure compatibility with different naval system components. These customization options maintain mil-spec valve durability by reducing maintenance and replacement costs.
Fully Conforming to Military Specifications
Danco valves’ durability is ensured by rigorous assessment and certification of conformance to the highest mil-spec standards, such as MIL-V-22549. Conformance guarantees the valve’s compliance with the high safety and performance standards required for mission-critical operations, ensuring a long and reliable service lifetime and reduced maintenance and repair needs.
Shock and Vibration-Tested in Accordance with Mil-Standards
Certain models of Danco valves are also shock-tested in accordance with MIL-S-901C and vibration-tested in accordance with MIL-STD-167-1, certifying their ability to withstand high-impact shock loads and endure continuous shipboard vibrations without performance degradation or mechanical failure. These rigorous tests ensure Danco valves maintain operational readiness and function even in extreme conditions.
