Frequently Asked Questions (FAQ):
-
What is the maximum operating pressure for this check valve?
Based on ASME B16.34, the pressure rating depends on the class and temperature. For Class 150, it is up to 285 psi at 100°F; for Class 300, up to 740 psi; and for Class 600, up to 1480 psi. Please consult our technical data sheet for specific values. -
Can this valve be used for vertical pipelines?
Yes, the swing check design can be installed in vertical pipelines with upward flow direction. However, for vertical installations with downward flow, a spring-assisted or tilting disc check valve may be recommended. -
What is the standard trim material?
The standard trim is 13Cr stainless steel. For higher corrosion resistance, we offer SS304 or SS316 as optional upgrades. -
Is the valve suitable for seawater cooling water?
WCB cast steel is suitable for fresh water, but for seawater or brackish water, we recommend opting for a corrosion-resistant coating (e.g., epoxy) or selecting a nickel-aluminum bronze body. Please contact us for specific recommendations. -
What certifications are included?
Our valves are manufactured under ISO9001 quality management system. Material certificates, test reports, and pressure test certificates are provided upon request. -
What is the lead time for standard orders?
For standard sizes (2"-12"), the lead time is typically 15-30 days. Larger sizes may require 30-45 days. Urgent orders can be expedited based on availability. -
Do you provide sample support?
Yes, we can provide samples for evaluation. Sample cost and shipping terms are negotiable. -
How do I select the correct pressure class?
Determine the maximum operating pressure and temperature of your system. Refer to ASME B16.34 pressure-temperature tables. For cooling water pipelines, Class 150 or Class 300 is common. If unsure, our technical team can assist you.
