Burkert 0330-41107 3/2-way-solenoid valve
Product Description
1. Basic Features
Type: 3/2-way pilot solenoid valve (3 ports, 2 positions)
Drive mode: electronic control (solenoid coil) + pneumatic pilot (external air source required)
Action form:
Normally closed (NC): closed when powered off, ventilated when powered on
Normally open (NO): optional (suffix required)
2. Core parameters
Project specifications
Valve body material: brass (standard), stainless steel (316L, corrosion resistant)
Seal material: NBR (nitrile rubber), FKM (fluoro rubber) or PTFE (polytetrafluoroethylene)
Interface size: G1/8", G1/4" or NPT1/8 (specific model suffix required)
Pressure range: 0.5~10 Bar (pilot design, low pressure difference requires a minimum of 0.5 Bar start)
Temperature range: -10℃~+90℃ (NBR seal); -20℃~+150℃ (PTFE seal)
Flow coefficient (Kv): about 0.5~1.2 m³/h (DN4-DN8, please refer to the table for details)
Response time: <50ms (pilot structure, fast switch)
Electrical parameters: 24V DC/AC, 110V AC or 220V AC (coil power is usually 4~8W)
3. Working principle
Pilot design:
When power is on, the electromagnetic force opens the pilot hole and uses the medium pressure to push the main valve core;
When power is off, the spring resets to close the main valve.
Interface function:
1 (P): Pressure inlet
2 (A): Working outlet
3 (R): Exhaust port (or oil return port)
4. Typical applications
Pneumatic control system:
Cylinder single-acting control (such as clamping/unclamping)
Vacuum generator switch
Industrial automation:
Purge system valve switching
Lubrication system oil circuit control
5. Product features
Low pressure difference start: Pilot design is suitable for low pressure applications (minimum 0.5 Bar).
Energy-saving design: Pilot structure reduces coil power consumption.
Modular options:
Manual operation (with emergency switch knob)
Indicator light shows valve position status
