Product Description

Description

The KLD20S Super Mini 2-Way Motorized Ball Valve with male-female connections features a compact design suitable for small equipment and utilizes patented floating seal technology, ensuring a long service life of 70,000-100,000 cycles. Constructed with brass and stainless steel materials, it offers excellent durability and reliability. The valve is equipped with a manual override function for use in case of power failure and features an IP67-rated enclosure for enhanced protection against dust and water ingress. An optional high-speed version with a 2-second opening/closing time is also available.

Technical specifications include

Valve type: Super Mini 2-Way Motorized Ball Valve
Diameter: DN10, DN15, DN20
Pressure: Maximum 1.0 MPa（PN10)
Flow: Variable with valve size and application
Medium temperature: 0°C to 100°C
Ambient temperature: -20°C to 45°C

The KLD20S is ideal for replacing solenoid valves, particularly in applications where solenoid valves may not operate reliably. It is suitable for use in HVAC systems, water treatment plants, chemical processes, and small equipment requiring automatic control. Its robust design and high-performance features make it a reliable choice for industrial and commercial applications.

CE approved

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℃.

※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.
