Description
The compact Normal On/Off 2‑Way Motorized Ball Valve belongs to the KLD30S/SJ Series. It uses male and female thread connections for direct pipe installation. Two variants are available: the 30S with manual override, and the 30SJ without. The valve body is 304 or 316L stainless steel. The ball and stem are also 304/316L. PTFE seats and EPDM/NBR/FPM seals provide chemical resistance. The full-port design minimizes flow restriction. 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: 2-Way Motorized Ball Valve (Male x Female)
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 male and female thread configuration allows direct inline connection without adapters. It fits small equipment and tight spaces. 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
