  •  
    Check Valves - (1883 companies)
    ...that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. Fluid flow in the desired direction opens the valve, while backflow forces the valve closed...
  •  
    Rust and Corrosion Inhibiting Fluids - (398 companies)
    Rust preventives and corrosion inhibitors are lubricants, greases, oils or fluid additives that form a protective film or barrier to prevent corrosion or rust formation. Rust preventatives and corrosion inhibitors are lubricants, greases, oils...
  •  
    Refrigerants, Antifreezes, and Cooling Liquids - (209 companies)
    ...polyglycols and water-glycol fluids, fluorocarbons, and silicone-based greases and oils. They are formulated from alkaline organic and inorganic compounds and used in diluted form with concentrations ranging from 3% to 10%. Synthetic products are more...
  •  
    Water Valves - (573 companies)
    Non-return or check valves control the direction of flow. Flow in the desired direction opens the valve, while flow in the oppose direction forces the valve closed. These valves are important for preventing backflow to systems in applications...
  •  
    Fusible Alloys - (15 companies)
    Fusible alloys have low melting points, usually below 300 o F. Many fusible alloys have eutectic compositions. Fusible alloys are used as work holders, electroforming mandrels, tube bending aids, fire sprinkler parts, steam boiler relief plug, resin...
