Description
The compact Normal On/Off 3‑Way Motorized Ball Valve from the KLD30S/SJ Series, offered in horizontal variants. It uses Tri-Clamp (BPE) connections for fast assembly. Two variants are available: the 30S has a manual override, and the 30SJ without. The valve body and ball are made of 304 or 316L stainless steel. PTFE seats and EPDM/NBR/FPM seals provide chemical resistance. This is a horizontal 3-way design. T-port and L-port flow directions are available. Water mixing may occur during rotation. The actuator delivers 3N·m torque. Protection is IP67. The actuator can be upgraded to a service life of up to 500,000 cycles. Manufactured under an ISO 9001 quality management system.
Technical specifications
Valve Type: 3-Way Motorized Ball Valve for Fast Assembled (Horizontal)
Sizes: DN10, DN15, DN20
Pressure: Maximum 1.0 MPa (PN10)
Flow: Varies with valve size and application
Medium Temperature: 0–100°C / 120°C / 150°C
Ambient Temperature: -20°C to 45°C (customizable) ※1
This valve is widely used in industrial automation, water-saving controllers, environmental protection and water treatment. The horizontal 3-way design with Tri-Clamp connections allows flow switching in sanitary piping systems. It fits small equipment and tight installations. The Tri-Clamp design enables quick disassembly for cleaning. Liquid and gas media are both supported. Optional high-temperature mounting brackets extend the range to 200°C.
※1 Customization is available for temperatures outside the range of>45°C or<-20°C.
① t<-40°C, connect power at least 15 mins (30 mins recommend) before usage.For higher ambient temperatures, warm-up time may be reduced.
② t<- 40°C for long time, add protection to the actuator, eg: heating cable.Not required at ambient t ≥ -15°C.
Applications
Industrial automation & instrumentation
Intelligent water-saving controllers & actuated terminals
Environmental protection, low-flow, water supply & drainage, water treatment
