Description
The KLD20S series electric three-way valve A, 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. The valve has an IP67 protection rating. Manual override function is available, it is very safe when there is power failure and convenient for users. If no need for manual override, you can choose 20SJ Series. Vertical 3-way is very suitable for space limited application, the special L ball can guarantee no medium mixing during valve ball rotation.
Technical specifications include
Valve Type: Three-way electric ball valve
Sizes: 1/2" to 1" (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, water treatment, chemical processes, medical equipments and small-scale automated control systems, offering an alternative to unreliable solenoid valves. It is constructed with a PC alloy actuator housing, nickel-plated brass valve/304/316L body, 304/316L/wearproof 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.
Fail safe function (capacitor return) optional.
Standard is 2 positions, if you need 3 or 4 positions or special flow pattern, feel free to contact us and we can customize.
CE approved
Applications
HVAC
Water treatment
Chemical process
Small equipment for automatic control
Replacing solenoid valve, particularly when solenoid cannot work reliably
