Product Description

Description

The KLD20T modulating 3-way motorized ball valve (1/4" to 1") features a special motor with long service life and utilizes rolling bearings for the output, allowing the actuator to reach a lifetime of up to 500,000 cycles. It adopts patented floating seal technology to prevent scaling, making it suitable for long periods of inactivity. The mini size is well-suited for small equipment, with manual operation available as an option. It comes with an intelligent interface, equipped with an OLED display showing the valve position. Optional features include fail-safe functionality and an LED indicator, with the LED providing on/off/alarm feedback. Fail safe(capacitor return) function, you can choose normally close or normally open.

Technical specifications include

● Valve type: 3-way modulating electric ball valve

● Size: DN8, DN10, DN15, DN20, DN25

● Connection: Threaded

● Pressure: Maximum 1.0MPa (PN10)

Instructions for Manual Override		Flow Characteristics
	It is only permitted to use when power is cut. Lift the hand-wheel,and turn it left or right slowly until the valve is in place. When the red line on the indicator is horizontal, the valve is on; when vertical, the valve is off. Press down hand-wheel after using manual override in order to work properly when power is supplied.
