Frequently Asked Questions (FAQ)
Q1: What is the maximum pressure rating available for this check valve?
A: The standard pressure rating is PN1.6–6.4 MPa. Higher ratings such as Class 600 (PN10) can be customized upon request.
Q2: Can the valve be used for other media besides fuel oil?
A: Yes. The design is also suitable for water, diesel, gas, and other non-corrosive fluids. For corrosive media, we recommend stainless steel or duplex materials.
Q3: What flange standards are supported?
A: By default we supply according to EN 1092-1 (PN) and ANSI B16.5 (Class). Other standards like JIS, GOST, or GB are available on request.
Q4: Do you provide valves with NACE compliance?
A: We can offer materials with NACE MR0175 compliance as an optional feature. Please specify your requirements when ordering.
Q5: What is the delivery time for standard sizes?
A: For DN15–DN100, typical lead time is 15–25 working days. Larger sizes (DN125–DN200) may require 25–35 working days depending on quantity.
Q6: Can the check valve be installed vertically or horizontally?
A: Swing check valves are recommended for horizontal pipes, while lift check valves can be installed in vertical pipes with upward flow. Our engineers can help you choose the correct disc type.
Q7: Do you offer a warranty?
A: Yes, we provide a standard 12-month warranty from date of shipment, covering any manufacturing defects. Extended warranty is negotiable.
Q8: How can I get a sample valve for testing?
A: Sample orders are welcome. Please contact our sales team with your size and pressure requirements, and we will prepare a quotation including sample cost and shipping.
