Common Questions on Ordering & Tech Specs
-
Q.
Can I order a sample to test the quality before a bulk order?
Yes, absolutely. We understand the importance of quality verification in industrial projects. We accept 1-piece sample orders for most of our standard products, including electric/pneumatic actuators and common valves. Contact us to get your sample shipped quickly. -
Q.
Can you help select the right valve if I provide my working conditions?
Absolutely. Our technical team can assist with sizing and selection. Just let us know your medium (fluid), temperature, pressure, and voltage requirements, and we will recommend the most cost-effective solution (e.g., choosing between a soft-seated or metal-seated butterfly valve). -
Q.
What connection standards can you manufacture? (ANSI, DIN, JIS, GB?)
We manufacture valves compliant with all major international standards to ensure global compatibility. Our production capabilities cover ANSI/ASME, DIN, JIS, and GB standards. Whether you need 150LB/300LB, PN10-PN64, or 10K/20K, we have you covered.If it’s a standard used in the market, we can make it. -
Q.
How do you ensure valve quality before shipment?
Each valve undergoes 100% inspection before shipment, including pressure testing, material analysis, and dimension checks according to international standards. -
Q.
What kind of after-sales service do you provide?
DELCO provides full after-sales support, including installation guidance, technical consultation, and a 12-month warranty for most valve models. Our service team responds within 24 hours to resolve any product issues.
