Inflatable PSI® valves are an economical solution to seal a pipe or tube for liquids, gases or dirt. The standard cylindrical PSI has a rubber diaphragm and is sheathed in waterproof PE-coated nylon.
The compact Low Profile® valves can be placed at any position in the pipe or a bend. Unevenness is easily compensated to seal safely and quickly.
RPP® rubber valves are highly resistant to oils, hydrocarbons and (petro)chemicals. This inflatable valve is made of sturdy durable rubber and easy to position and inflate.
PetroChem® inflatable valves are resistant to chemicals due to the high-quality nylon cover and latex inner membrane. Ideal for safely sealing pipes or tanks containing hazardous gases and liquids.
