Description
The KLD20S series two-way electric ball valve is designed for small-scale equipment applications. It features a compact size, a patented floating seal structure, and a long service life of 70,000 to 100,000 cycles. With low operating current, it is suitable for battery-powered systems. The valve has a manual Override for safe and convenient operation and an IP67 protection rating. If no need for manual override, you can choose 20SJ Series. Fail safe(capacitor return) function, you can choose normally close or normally open, so it is an better alternative to solenoid valves, with bigger flow rate and avoid water hammer. We offer different kinds of sealing material to meet different working medium request, such as water, air, glycol or other corrosive medium like disinfectant, etc. It is compact, robust and industrial standard, so it is also economical option to replace some traditional big type actuators to save cost.
Technical specifications include
Valve Type: Two-way electric ball valve
Sizes: 1/4" to 1" (DN8, DN10, DN15, DN20, DN25)
Pressure: Maximum 1.0 MPa (PN10)
Flow: Varies with valve size and application
Medium Temperature: 0°C to 100°C
Ambient Temperature: -20°C to 45°C
The valve is suitable for HVAC, RO, water treatment, chemical processes, water-saving and eco friendly system, smart home, analysis instrument, medical equipments and small automated control systems, etc. It is constructed with a PC alloy electric actuator housing, nickel-plated brass valve/304/316L body, 304/316L ball, brass/304/316L stem, PTFE seat, and EPDM, FPM, SI seals. Connection dimensions and weights are provided for different sizes.
Fast running 2s version or long service life are optional.
CE,Rohs, NSF approved
Applications
● HVAC
● Water treatment
● Chemical process
● Small equipment for automatic control
● Replacing solenoid valve, particularly when solenoid cannot work reliably

Instructions for Manual override
It is only permitted to use when power is cut.
Lift the hand-wheel, and turn it left or right until the valve is in place.
When the black 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.
Wiring
B2, B3, BD3,KT2 are available
Manual shaft and hand-wheel will be replaced by rubber seal if manual override function is not needed.
Actuators are not direct-mount-on. Actuators are not recommended to be sold separately.
