Burkert 5282-134446 2/2-way-solenoid valve
Product Description
1. Basic Features
Model: 5282-134446
Series: 5282 Series (Bürkert High-Performance Solenoid Valve Family)
Valve Body Type: 2/2-way Direct-acting Solenoid Valve (2 ports, 2 states)
Action Mode: Normally Closed (NC, Power-off Closed) or Normally Open (NO, suffix needs to be confirmed)
2. Core Parameters
Project Technical Specifications
Valve Body Material: Brass (standard), Stainless Steel (316L, Corrosion-resistant) or Plastic (PP/PTFE, Chemical Media)
Seal Material: NBR (-20℃~+80℃), FKM (-10℃~+150℃) or PTFE (-20℃~+180℃)
Pressure Range: Vacuum to 25 Bar (Direct-acting High-Pressure Model)
Flow Coefficient: Kv 0.1~4.0 (DN2.5~DN25, see the table for details)
Response Time: ≤15ms (Direct-acting Structure, No Pilot Delay)
Electrical Parameters: 24V DC/AC, 110V AC, 230V AC (coil power 4~21W, Class F insulation)
Protection level: IP65 (dustproof and waterproof, coil part)
3. Working principle
Direct acting design:
When power is on: electromagnetic force directly lifts the valve core, and the medium flows
When power is off: spring force resets, and the valve core seals and cuts off
Zero pressure difference start: no minimum working pressure difference is required (different from pilot valve)
4. Typical application scenarios
Industrial automation:
Emergency cut-off of compressed air
On-off control of vacuum system
Process industry:
Metering of corrosive chemicals (with PTFE valve body)
Ultrapure water system (sanitary design)
Energy equipment:
Safety shut-off of gas (ATEX explosion-proof version)
5. Product features
Compact design: 30% smaller than pilot valve, suitable for installation in limited space
Wide pressure difference compatibility: reliable operation within the full pressure difference range of 0~25 Bar
Optional functions:
Manual operation override (with mechanical locking knob)
Valve position status indicator (LED visualization)
Energy-saving coil (pulse power supply reduces power consumption)
