Pneumatic 2/2-way diaphragm valve made of plastic

GEMÜ R647

ConfigureTechnical data sheet
Pneumatic diaphragm valve made of plastic with screw connections – ideal for the chemical industry, water treatment, and process control.

Simple diaphragm valve for actuation with air or water

Product information

The GEMÜ R647 2/2-way diaphragm valve is a straight through valve and is pneumatically operated. The valve doesn't have a closing spring and is only closed by applying compressed air. A diaphragm is the sealing element. The control medium applies direct pressure to the shut-off diaphragm pressing it against the shut-off weir in the valve body. The high-flow valve body provides compact dimensions at high flow rates.

Key features

  • Suitable e. g. for dyeing plant, paper industry and automatic feeding installations
  • Operator solution without closing spring, ideal when space is limited
  • Compact, lightweight construction and high performance
  • Simple diaphragm replacement
  • Good flow characteristics due to flow optimised valve body
