Product Description
R647 15D 0 1 25 ED / 88412359
Description
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.
Features
- 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
- Good flow characteristics due to flow optimised valve body
