Frequently Asked Questions (FAQ)
Q1: Is this valve suitable for continuous seawater exposure?
A1: Yes, the 316L stainless steel construction offers excellent resistance to seawater corrosion. However, periodic maintenance is recommended to remove marine growth.
Q2: What flange standard is used – JIS 10K or others?
A2: The flanges are designed per JIS B2220 10K rating. We can also supply with ANSI 150 or DIN PN16 flanges upon request (customization available).
Q3: What is the maximum working pressure?
A3: For JIS 10K rating, maximum allowable working pressure is approximately 1.0 MPa (145 psi) at ambient temperature. Higher temperatures reduce the pressure rating – refer to our pressure-temperature chart.
Q4: Do you provide certificates of material or testing?
A4: Yes, material test certificates (MTC) and hydrostatic test reports are available upon request at no extra charge for standard orders.
Q5: Can I get the valve with a pneumatic or electric actuator?
A5: Currently our standard design is handwheel-operated. Actuator mounting is possible as a custom option – please contact our sales team for details.
Q6: What is the lead time for DN150 size?
A6: For standard materials and finish, lead time is typically 15–20 working days after order confirmation. Rush delivery may be arranged at an additional cost.
Q7: How do I ensure correct valve selection for my piping system?
A7: Provide the working pressure, temperature, medium, and flange standard. Our engineers can assist you in selecting the appropriate size and material grade.
Q8: Is the valve supplied with a counter flange or gaskets?
A8: Typically the valve is supplied alone. Flanges, bolts, and gaskets can be packaged together as a set upon request.
