Frequently Asked Questions (FAQ)
Q1: What does “10K” mean in JIS F7312 globe valves?
A: “10K” refers to the pressure rating according to JIS standards, approximately equivalent to PN16 or Class 150. It indicates the valve can withstand a maximum allowable working pressure of about 1.0 MPa at ambient temperature.
Q2: Can this valve be used for steam applications?
A: Yes, the carbon steel WCB body and appropriate packing materials (graphite or PTFE) allow operation with steam up to 425°C. For higher temperatures, optional upgrades are available upon request.
Q3: Are these valves supplied with test certificates?
A: Yes, each valve comes with a hydrostatic test certificate and material certificate as standard. Additional third-party inspection can be arranged.
Q4: What is the lead time for DN200 and above sizes?
A: Standard sizes DN50-DN150 are usually in stock. Larger sizes DN200-DN300 may require 15-30 days production lead time depending on order quantity. Please consult our sales team for exact scheduling.
Q5: Are flanges compatible with other standards (ANSI, DIN)?
A: The valve is designed with JIS B2220 10K flanges. If you need ANSI or DIN flanges, we can produce custom flanges with the same body pattern. Contact us for feasibility and pricing.
Q6: How do I ensure the correct flow direction?
A: The globe valve is typically installed with flow under the disc for better shut-off. An arrow is cast on the body to indicate the recommended direction. Reverse installation is possible but may affect performance.
Q7: Do you offer gearbox or actuator options for larger sizes?
A: Yes, for handwheel operation on larger valves (DN250 and above), we can provide a gearbox to reduce operating torque. Electric or pneumatic actuators are also available as customization options.
Q8: What packaging do you use for export shipment?
A: Each valve is individually wrapped with plastic protection, and flanges are covered with caps. The valves are packed in sturdy plywood cases or pallets suitable for ocean freight, ensuring safe arrival.
