Burkert Type 6027 (Model 307840) is a direct-acting, powerful 2/2-way plunger valve designed for the reliable control of neutral gases and liquids. To enhance pressure resistance and leak-tightness, the stopper and plunger guide tube are welded together. The coils are moulded with chemically resistant epoxy. An optional sliding ring bearing increases the service life with dry gases.

This specific model features a 6.0 mm orifice, a robust stainless steel body, an NPT 1/4 internal thread, and an FKM (Fluor rubber) seal. It operates at 240V (60 Hz) and is capable of handling a pressure range of 0 to 5.5 bar. In combination with a plug in accordance with DIN EN 175301-803 Form A, the valve satisfies protection class IP65.

Key Features

• Direct-acting, powerful valve with a diameter of up to DN 13
• Vibration-proof, bolted coil system
• Energy-saving double coil technology with kick and drop variant available
• Explosion-proof variants available
• High-pressure variants for gases and liquids available

Safety Instructions

High Pressure & Electrical Voltage

• Risk of injury from high pressure in the system: Before loosening lines or valves, switch off the pressure and vent the lines.
• Risk of injury from electric shock: Before working on or inside the device or the system, switch off the power supply and secure against reactivation. Observe the applicable accident prevention and safety regulations for electrical devices.

Hot Surfaces

Risk of burns from hot device surfaces: Do not touch the device with your bare hands. The coil can become very hot during continuous operation.
