Air Operated Pinch Valve Sleeve Qualities
Air Operated Sleeves – Part Number Codification
RV Series Mechanical Valve Sleeves – Part Number Codification

  • Neoprene – Resistant to dilute solvents, oils, acids, lubricants, various hydrocarbons and mild chemicals. Applications such as animal oils, natural gas, printing ink and soaps.
  • Natural Rubber, Food Grade – Suitable for many weak chemicals, potable water, wine and alcohols.
  • Natural Rubber, Abrasive Resistant and High Temp – Excellent abrasive resistance with a high degree of flexibility and durability. Ideal for foundry sand, silica sand, metals, waste water, mineral slurries, cement, concrete, granules and plastics.
  • EPDM – Great for higher temperature applications such as hot water, steam, foods and CIP applications where elevated temperatures are used. Also excellent for dilute acids and alkalis.
  • Viton – Resistant to solvents, oils, petrochemicals, aromatic hydrocarbons. Applications range from battery acid to buttermilk.
  • Silicon – Highest temperature material mainly used to exhaust very hot steam or sulfuric acid.
  • Nitrile – Best suited for products with oil or fat content. Examples sewage with trace oils, milk, butter, chocolate, fish, vegetable oils, olive oil, mineral oils, processed beef meal, etc.
  • Hypalon – Similar to Nitrile and EPDM applications. Applications such as chloride, peroxide and acids.
  • Butyle – Various chemical applications such as alcohol, amino acids, barium, ammonium, and acetic acids.
