When it comes to designing high-pressure hydraulic circuits, materials matter. In fact, the materials of construction you choose for your high-pressure water valves have a long-term impact on the performance of the valve as well as the overall hydraulic system.
But what about the seals, gaskets and packing? To help guide your selection, here are some characteristics of popular materials of construction for these industrial valve components:
Designed for temperatures up to 200 degrees Fahrenheit
Ideal for pressures up to 6,000 psi
Excellent abrasion resistance
Excellent chemical resistance
Works well at high temperatures
3. Polytetrafluoroethylene (ptfe)
Extremely low friction
Designed for a wide range of pressures and temperatures
4. glass-filled ptfe
Improved creep resistance
Improved wear resistance and heat transfer
5. polyetheretherketone (peek)
Ideal for steam applications
High temperature rating
Good corrosion resistance
counting the cost
As we've discussed in past blog posts, application parameters and flow media incompatibilities will generally drive valve material decisions, with cost coming in almost immediately behind. In most cases, you should select the lowest cost valve that performs the intended function and is constructed of materials that are compatible with the flow media.
For some applications, the service or replacement schedules of certain valve components can be extended by using a more expensive material of construction. That additional cost may be worth it, especially in applications where scheduled downtime must be minimized.
