Needle dispensing valve

high-speedprecisionelectro-pneumatic actuator

Product description
Shot valves are extremely fast-switching valves designed for contactless application of grease and oil in automated processes. They are capable of dispensing very small amounts of material at speeds of up to 200 cycles per second. This performance is achieved by an integrated 5/2-way solenoid valve used for control and by short paths throughout the air supply system. Valves are available with short and long nozzles covering various application angles; different nozzle sizes allow processing of media with different viscosities.

Features

• Contactless shot application (pressure-time dosing)
• Nozzle size Ø 0.2 - 1.0 mm
• Maximum input pressure: 100 bar
• Integrated 24 V DC solenoid valve for maximum shot frequency
• 200 Hz (SHV-01) / 30 Hz (SHV-02) depending on model
• Adjustable needle rise (raster regulation) for shot size control

Options

• Stroke detection device with cable
• Nozzle extensions with various lengths and shot angles
• 24 V / 50 W heating with PT100 temperature sensor
• Silencer kit
• Pressure sensor
• Light barrier for shot detection
• Rotary applicator

Applications / Additional information
Shot valves are used for fast and precise contactless greasing and oiling in highly automated production processes, for example in the automotive industry. A product video demonstrates contactless greasing applications and the valve's suitability for automated production lines.
