Description
The KLD20S series Super Mini 3-Way Motorized Ball Valve with Tri-clamp connections is specifically designed for small-scale equipment applications, offering a compact and efficient solution for fluid control. This valve features a patented floating seal structure that ensures excellent sealing performance and a long service life of up to 70,000-100,000 cycles. Constructed with high-quality materials, including brass with nickel plating, stainless steel (304/316L), and PTFE seals, it provides robust durability and corrosion resistance. The valve is equipped with a manual override function for safe and convenient operation during power outages. For applications where manual override is not required, the KLD20SJ series is available. The horizontal 3-way design offers higher flow rates and a wider range of valve sizes compared to vertical 3-way valves. However, users should note that medium mixing may occur during valve ball rotation in the 3-way B type; if this is a concern, the 3-way A type can be considered as an alternative.
Technical specifications include
Valve Type: Three-way electric ball valve
Sizes: DN10, DN15, DN20
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 KLD20S series valve is suitable for a wide range of applications, including water treatment systems (RO, filtration, backwash), HVAC systems, chemical processes, medical equipment, and small-scale automated control systems. It provides a reliable alternative to solenoid valves, especially in cases where solenoid valves may not operate reliably. The valve's modular design and optional configurations (e.g., 2-position, 3-position, or 4-position) allow for customization to meet specific application requirements.
CE approved
Applications

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 arrow mark 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.We can accept feedback customization.Please contact sales for more details.
The service life is the testing data in the condition of 1.0Mpa, 200L/h, tap water as working medium. Different working occasions will influence the service life.
KLD20S has manual override; KLD20J does not have manual override, other parameters are the same as KLD20S.
Actuators are not direct-mount-on. Actuators are not recommended to be sold separately.
The pressure is tested under one-way direction.
※1 It needs to add high-temperature bracket if medium temperature is over 100 °C.
※2 Avoid direct or indirect contact between PC and organic solvents such as toluene, xylene, ketones, dichloromethane, trichloromethane, and chloroform ect., due to corrosion resistance characteristics of PC materials.
