Frequently Asked Questions
-
Q: What is the difference between 5K and 10K pressure ratings?
A: 5K valves are rated for 0.5 MPa (approx. 73 psi) working pressure, while 10K valves handle up to 1.0 MPa (145 psi). Choose based on system design pressure. -
Q: Can this valve be used for seawater?
A: Yes, cast iron with proper coating is suitable for seawater. We recommend an epoxy lining for enhanced corrosion resistance in saltwater applications. -
Q: Is the Mill Test Report provided free of charge?
A: Yes, a standard Mill Test Report covering material and pressure test results is included with every shipment at no extra cost. -
Q: Do you offer valves with other flange standards (e.g., ANSI, DIN)?
A: Our standard production is JIS B2220 flanges. Custom flanges (ANSI, DIN, etc.) are available as a made-to-order option with additional lead time. -
Q: What is the typical lead time?
A: For standard sizes (DN15-DN100), lead time is 15–25 days after order confirmation, depending on quantity and production schedule. -
Q: Can the valve be installed in any orientation?
A: The angle stop valve is designed for horizontal or vertical piping. For optimal performance, install with the handwheel pointing upward or horizontally accessible. -
Q: Do you provide OEM/private labeling?
A: Yes, we can apply your brand name and logo on the valve body or nameplate. Please discuss requirements with our sales team. -
Q: What packing material is used for the stem seal?
A: Standard packing is graphite-impregnated PTFE, suitable for water and oil media. Alternative packing materials can be supplied upon request.
