German schnupp valves schnupp models schnupp prices

schnupp valves are globe valves that use a diaphragm as the closing element to seal the flow passage, shut off fluid, and separate the valve body cavity from the valve bonnet cavity. Diaphragms are commonly made of elastic, corrosion-resistant, non-permeable materials such as rubber and plastic. Valve bodies are mostly made of plastic, fiberglass, ceramic, or metal with rubber lining. They feature a simple structure, good sealing and anti-corrosion performance, and low fluid resistance. They are used for media with low pressure, low temperature, strong corrosiveness, and suspended solids. Structural forms include weir type, globe type, and gate type. Drive methods include manual, pneumatic, and electric. sch
