Description
The KLD30S/SJ Normal On/Off 4‑Way Motorized Ball Valve with female thread connections is in a horizontal configuration. Available in DN15. The valve body and bonnet are constructed from 304 or 316L stainless steel. The ball comes in 304/316L or a special wear-resistant option. Multiple flow patterns are available: T-port, L-port, I-port, and Double L-Port 90°. PTFE ball seats ensure reliable sealing. The 30S model includes a manual override handwheel. The 30SJ omits it for compact installations. 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: 4-Way Motorized Ball Valve (Horizontal)
Sizes: DN15
Pressure: Maximum 1.0 MPa (PN10)
Flow: Varies with medium
Medium Temperature: 0–100°C / 120°C / 150°C
Ambient Temperature: -20°C to 45°C (customizable) ※1
This valve is designed for fluid diversion and distribution in industrial automation, water treatment, and environmental protection systems. The 4-way horizontal design routes flow between four ports with flexible T, L, I, or Double L-Port ball configurations. Female thread connections allow direct integration into standard piping systems. Suitable for both liquid and gas media. The compact horizontal layout fits tight equipment spaces.
※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
