Frequently Asked Questions (FAQ)
-
Q: Is this valve suitable for seawater intake lines as well?
A: While robust, this standard model is primarily designed for sewage, bilge, and gray/black water systems. For direct seawater service, we recommend valves with more corrosion-resistant materials like super duplex stainless steel or specially coated internals, which we can provide upon request. -
Q: Can the valve be supplied with different end connections, like threaded ends?
A: The standard offering for DN50-DN200 is flanged connection due to its reliability and prevalence in marine piping. For smaller sizes or specific applications, threaded (NPT/BSP) or socket weld ends can be explored as a customization option. -
Q: What is the lead time for an order of DN100 valves?
A: Lead times vary based on order quantity and current production schedule. For standard DN100 valves, typical production time is 15-30 days. We maintain some stock for common sizes; please inquire for the most accurate delivery schedule. -
Q: Do you provide actuated versions for remote control?
A: Yes. While supplied with a manual lever as standard, this valve series can be easily fitted with pneumatic or electric actuators for automated control systems. We offer a range of actuator brands and types to suit your control requirements. -
Q: How does the epoxy coating hold up in submerged or splash zone conditions?
A: Our standard epoxy coating is a high-quality, chemically resistant paint designed for marine environments. It provides excellent protection against splash and atmospheric corrosion. For permanently submerged service or more aggressive conditions, we can apply enhanced coating systems like heavy-duty epoxy or fusion-bonded epoxy (FBE). -
Q: Are spare parts like seals and gaskets readily available?
A: Absolutely. We maintain an inventory of critical spare parts for our valve models. Seal kits (stem seals, seat rings) and gasket sets can be ordered separately to facilitate maintenance and extend the valve's operational life. -
Q: What documentation is provided with the valve shipment?
A: Each shipment is accompanied by a commercial invoice, packing list, and a certificate of compliance/conformity. Material test certificates (MTC) and detailed inspection reports are available upon request for critical applications. -
Q: Can you produce valves according to specific naval or classification society standards?
A: We have experience manufacturing valves to various international standards. While our standard production follows common industrial norms, we can discuss manufacturing valves to meet specific requirements from classification societies like ABS, DNV, LR, etc., subject to technical review and agreement.
