FAQ

What information do I need to provide to get a quotation?
To provide an accurate quotation, please share the following details: media type, temperature range, pressure class, valve size, connection type, actuation method (pneumatic/electric), and any special requirements such as ATEX certification or custom materials. For control valves, flow rate and desired Cv value are also helpful.
What is the difference between pneumatic and electric actuators? How do I choose?
Pneumatic actuators offer fast response (≤0.5 sec), high cycle life (1M+ cycles), and are ideal for fail-safe applications where compressed air is available. Electric actuators provide precise positioning (±1% accuracy), quiet operation (≤55dB), and require no air supply – best for clean, energy-efficient environments. Selection depends on power source availability, fail-safe requirements, torque needs, and control functions (on/off or modulating).
Do you support custom or non-standard valve solutions?
Yes. KINKO specializes in custom solutions for non-standard applications. We support full OEM/ODM customization including special dimensions, pressure ratings, materials (WCB/CF8/316L/Hastelloy/PTFE-lined), connection types, actuation configurations, and brand customization. Custom lead times are typically 5-7 days – faster than industry average.
What certifications do KINKO products hold?
KINKO products are certified to CE, SIL3, IP68, FDA, ATEX, 3A, ISO9001, and API607 standards. Certification documents are available for download on each product page. For projects requiring specific certifications, please specify your requirements when requesting a quotation.
What is the standard delivery time and warranty?
Standard products with stock availability ship within 3 days. Custom orders are delivered in 5-7 days. KINKO offers an 18-month warranty (industry standard is typically 12 months) with 24/7 technical support and lifetime service commitment. International shipping is available with full logistics and customs clearance support.
