Frequently Asked Questions (FAQ)
-
Q: What is the difference between a cock valve and a ball valve?
A: A cock valve (also called a plug valve) uses a cylindrical or tapered plug with a passage to control flow, while a ball valve uses a spherical ball. Cock valves offer a more compact design and are often preferred for on/off service in smaller sizes like DN40. -
Q: Is the valve suitable for seawater?
A: Yes, the bronze material and anti-corrosive coating make it specifically designed for marine and seawater applications. However, we recommend selecting the appropriate seal material (e.g., PTFE or NBR) based on the fluid temperature. -
Q: Can the valve be used in vertical pipelines?
A: Yes, the wafer type design can be installed in both horizontal and vertical pipelines, as long as proper flange support is provided. -
Q: What is the pressure test procedure?
A: Each valve is hydrostatically tested at 1.5 times the rated pressure (15 bar for PN10) for a minimum of 30 seconds, with no visible leakage. A test certificate is available upon request. -
Q: Do you provide a material certificate?
A: Yes, we can provide a mill test certificate for the bronze material, as well as a pressure test certificate, at an additional cost. Please inquire when placing an order. -
Q: What is the typical lead time?
A: Standard lead time is 15–20 working days for quantities up to 500 units. Larger orders may require 25–30 days. Expedited shipping is available for urgent needs. -
Q: Can I get a sample before bulk order?
A: Yes, we offer samples for evaluation. The sample cost is refundable for bulk orders, and shipping charges are borne by the buyer. -
Q: How do I install the wafer type valve between flanges?
A: The valve is centered between two flanges with bolts passing through the valve body holes. Use appropriate gaskets on both sides and tighten bolts evenly to the torque specified in the installation manual.
