German valtaco valves valtaco models valtaco prices

valtaco valves are stop 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 corrosivity, and suspended solids. Structural forms include weir type, straight-through type, and gate type. Actuation methods include manual, pneumatic, and electric. val
