 Pinch valves
Next to silos the pinch valves SQV are also used in several pneumatic conveying
systems of the chemical and pharmaceutical industries, sand, concrete and
cement industries, glass, ceramic and plastics industries as well as in dosage and
weighing systems.
The basic valves are available from DN 40 to DN 200.
The exchangeable sleeve is available in different elastomers for most diverse
requirements. The housing and cone flanges of the valves are available in
aluminium (standard), stainless steel or grey cast iron. As standard the sleeve is
made of black natural rubber (NR), on request it is also available in white natural
rubber (food-safe) and electrically conductive (ATEX).
The pinch valve closes by adding control air to the sleeve. By removing the control
pressure the sleeve opens up to its full cross section. The design of the housing
ensures proper closing of the sleeve and therefore safeguards the product flow to
be shut-off absolutely tight as well as a maximum service life of the sleeve. Even
larger solid particles are tightly covered and shut off.
