GEMÜ R647

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 valve is mainly made of three components, a valve body, a shut off diaphragm and a cover with control medium connector. 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.

• Compact, lightweight construction and high performance
• Simple diaphragm replacement
• Suitable e. g. for dyeing plant, paper industry and automatic feeding installations
• The valve can be used in all applications where a closing spring is not required and where space is at a premium
