Frequently Asked Questions
-
Q: Can this valve be used for seawater?
A: Yes, it is specifically designed for marine applications including seawater. Cast iron with proper coating and stainless steel trim resists saltwater corrosion. -
Q: What is the difference between a globe check valve and a standard check valve?
A: A globe check valve combines the throttling capability of a globe valve with the backflow prevention of a check valve. It uses a movable disc that can be manually positioned to regulate flow, while still acting as a non-return device when closed. -
Q: Are the flanges compatible with ANSI standards?
A: We supply flanges in DIN, ANSI, BS, and JIS drillings. Please specify your required standard when ordering. For standard stock, DIN flanges are the default. -
Q: Is the handwheel removable for actuator mounting?
A: The standard model is manual handwheel operation. For automated versions (pneumatic/electric), we offer customization. Please contact us for actuator adaptions. -
Q: What is the maximum working temperature?
A: Standard design handles -10°C to +80°C. For higher temperatures (up to 250°C), we can provide cast steel bodies upon request. -
Q: How do I confirm the LR and ABS certification?
A: Each valve is supplied with a material certificate and type approval certificate from LR and ABS. Copies of the certificates can be provided prior to shipment. -
Q: What is your typical lead time?
A: For standard sizes (DN50-DN200, PN1.0/1.6), lead time is 15–25 working days. Custom orders may require 30–40 days depending on quantity. -
Q: Can you provide spare parts such as disc and seat rings?
A: Yes, we stock spare parts for most sizes. Please request when placing your order or contact our after-sales team.
