Design Principles
Why are KINKO Control Valves so durable?
- Pneumatic actuators operate independently of the working medium via piston rod connection
- Self-adjusting packing ensures long-term, leak-free dynamic sealing
- Bi-directional flow capability; for liquids, flow should close against the seat to prevent water hammer

Industrial Internet of Things, cloud control, big data analysis, pre diagnostic platform
Users can easily form an industrial Internet of Things through Bluetooth, WiFi, LORA, NB-IoT, Zigbee, GPRS, 4G, 5G and other methods, directly realizing remote wired and wireless control and communication. They can also access cloud data to achieve multi-screen control via industrial computers, mobile phones, tablets, etc., monitoring the operation status and data recording of valves, real-time monitoring and control of pipeline fluid flow, temperature, pressure, etc. At the same time, based on cloud data analysis, they can provide customers with pre-diagnostic reports on the status of actuators, valves and other equipment to help users maintain equipment more scientifically.
- Flexible connectivity – Supports Bluetooth, WiFi, 4G/5G, LORA, NB-IoT, and more for remote wired or wireless control.
- Real-time monitoring – Enables multi-screen access to valve status, flow, temperature, and pressure data anytime, anywhere.
- Predictive maintenance – Cloud-based data analysis generates pre-diagnostic reports, helping users identify issues before they fail.
FAQ
How do I choose between equal percentage and linear flow characteristics?
Equal percentage characteristic is preferred when system pressure drop varies significantly (typical in most process control), providing consistent control throughout the stroke. Linear characteristic is suitable when pressure drop is relatively constant. Our engineers can assist with selection based on your specific loop conditions.
What is the typical control accuracy of KINKO control valves?
Standard accuracy is ±1% FS with positioner integration. High-precision options achieve ±0.5% FS. Accuracy depends on valve size, actuator type, positioner quality, and process conditions.
What does SIL3 certification mean for control valve applications?
SIL3 (Safety Integrity Level 3) certification indicates the valve meets the highest reliability standards for critical safety loops such as Emergency Shutdown (ESD) and High-Integrity Pressure Protection Systems (HIPPS), with a very high probability of performing its safety function when required.
What materials are available for corrosive media handling?
Valve bodies can be supplied in WCB, CF8, CF8M, 316L, Hastelloy C276, and PTFE-lined options. Trim materials include 316L, Hastelloy, Stellite hardfacing, and ceramic for abrasive service. Material selection depends on media type, temperature, and pressure.
What is the recommended operating range for control valve opening?
For optimal control, the valve should operate between 20% and 80% open at normal flow conditions. Avoid operating below 20% open (risk of poor control and cavitation) or above 85% open (loss of control authority). Valve sizing should be verified by Cv calculation.
