Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a JIS F7481 standard valve?
A: The JIS F7481 standard specifies dimensions, materials, and performance criteria, ensuring interchangeability and reliable performance in applications where this Japanese industrial standard is specified or preferred, particularly in Asian and international markets. -
Q: Can this valve be used for throttling (flow control) applications?
A: Yes, with an appropriate actuator (electric or pneumatic), this butterfly valve can provide effective flow modulation. However, for precise throttling, it is recommended to consult with our technical team for the optimal disc and seat configuration. -
Q: What kind of on-site installation guidance do you provide?
A: Our support includes detailed installation manuals, CAD drawings, and, if required, remote video consultation. For critical or large-scale projects, on-site technician supervision can be arranged to ensure correct installation and commissioning. -
Q: Are your valves compatible with other flange standards like ANSI or DIN?
A: While the valve is designed to JIS F7481, flanges can often be manufactured to match ANSI or DIN standards upon request. Please provide your specific flange rating and facing details for confirmation. -
Q: What is the typical delivery time for large diameter valves?
A: Lead time varies based on size, material, and actuation requirements. Standard configurations typically have a shorter lead time. We recommend contacting our sales team with your specifications for an accurate delivery schedule. -
Q: How do I select the right seat material (EPDM, NBR, PTFE)?
A: Selection depends on the fluid media, temperature, and pressure. EPDM is suitable for hot water and mild chemicals; NBR is common for oils and fuels; PTFE offers excellent chemical resistance. Our technical team can assist you in making the best choice. -
Q: Do you offer a warranty on your butterfly valves?
A: Yes, we offer a standard warranty against manufacturing defects. The specific warranty period and terms are provided with the commercial proforma invoice. -
Q: Can you supply the valve with actuators and control systems?
A: Absolutely. We can provide a complete package including the valve, actuator (electric/pneumatic), positioners, and limit switches as a fully assembled and tested unit, ready for installation.
