Frequently Asked Questions (FAQ)
Q1: What does "10K" mean in the valve specification?
A1: "10K" refers to the pressure rating standard in JIS (Japanese Industrial Standards). It indicates the valve is designed for a nominal pressure rating of 10 kgf/cm², which is approximately equivalent to PN16 (16 bar) in other standards.
Q2: Can this valve be used with fluids other than seawater?
A2: Yes. While designed for marine service, it is suitable for a variety of fluids including fresh water, fuel oil, lubricating oil, and air, provided the fluid is compatible with the valve's construction materials.
Q3: Are the flanges compatible with ANSI or DIN standards?
A3: The standard offering complies with JIS flange dimensions. However, as a manufacturer, we can often provide valves with ANSI, DIN, or other flange standards upon request. Please specify your requirement when inquiring.
Q4: What is the advantage of a rising stem design over a non-rising stem?
A4: The rising stem provides a clear visual indication of the valve's open/closed status, which is a critical safety feature. It also typically keeps the threads outside the valve body, protecting them from the flow media and reducing corrosion and wear.
Q5: What materials are available for the body and trim?
A5: Common body materials include cast steel (SC450) and cast iron. Trim materials (stem, seat) are often stainless steel and bronze. Specific material grades can be discussed based on your application's corrosion and pressure requirements.
Q6: Is this valve suitable for on/off service only, or can it be used for throttling?
A6: Gate valves are primarily designed for isolation (fully open or fully closed) and are not recommended for throttling or flow regulation, as it can cause vibration, seat damage, and accelerated wear.
Q7: Do you offer actuated versions of this valve?
A7: Yes. Manual handwheel operation is standard, but we can provide options for electric, pneumatic, or hydraulic actuation to suit automated control systems.
Q8: What is your typical lead time for an order?
A8: Lead time depends on the order quantity and specific configuration. For standard sizes and materials, we often have stock or short production cycles. We provide accurate lead time estimates with every quotation.
